Hi,

We just fixed a couple of problems with this version and uploaded a new binary. Could you give it a second try?
Thank you for your patience!

Hi,

I am pleased to announce we just publicly released Webots 6.2.beta1. This is a major upgrade which introduces a much better 3D rendering engine (based on OGRE 3D) among other features and bug fixes. You can download it from here: http://www.cyberbotics.com/beta/ (Linux i386, Linux x86-64, Mac OS X and Windows versions). Please send us your feedback about this beta version as we could not test it on every combination of operating systems, CPU, graphics cards, etc. This will help us prepare the final release of Webots 6.2.0.

Here is a copy of the change log since version 6.1.5:

Released on November 19th (revision 4280)

• Added compatibility with Windows 7: fixed printf() redirection in Webots console and freeze when using Build/Compile/Clean buttons
• Removed unused API functions: wb_supervisor_field_get_mf_rotation(), wb_supervisor_field_set_mf_rotation(), wb_supervisor_field_get_mf_bool() and wb_supervisor_field_set_mf_bool()
• Removed obsolete Gripper node (mainly used in old Khepera worlds)
• Fixed texture path problem with controller rendered camera images
• Removed the useless "display" field from the Camera node
• Fixed crash and improved the behavior of the find/replace dialog with respect to multiple buffers
• Migrated the Webots rendering system to OGRE 3D (Object-Oriented Graphics Rendering Engine)
• Modified the rendering of the lights and of the materials in order to fit better the VRML specifications
• Improved the lighting model; the ambient, diffuse and specular fields can behave differently
• Improved the rendering of every worlds (mainly the worlds of the guided tour and of robotstadium)
• Added support for texturing the Cone, the Cylinder and the Sphere primitives
• Added a subdivision field to the Cone primitive
• Improved the TextureTransform node (supported in every primitive able to have a texture)
• Improved the rendering abilities
• Improved the shadows; shadows are now volumetric, transparent, additive, and are casted from and received to any renderable object
• Improved the transparent object management (the render of transparent object is no more dependent on their position in the scene tree but are sorted according to their center)
• Added the "Wireframe" rendering mode which allows to display the segments of the renderable primitives
• Added the experimental "High Quality" rendering mode which allow to render the diffuse and specular lights per-pixel instead of per-vertex
• Refactored the Preferences dialog box and the View menu
• Added the lineScale field to the WorldInfo node in order to control the length of every arbitrary-sized lines
• Improved the anti-aliasing of the Camera primitive which is now computed by the hardware
• Moved the far clipping plane to infinity
• Removed the far field from the Viewpoint and the Camera nodes
• Removed the wb_camera_get_far() function
• Improved the range-finder cameras
• Improved significantly the performances of the range-finder cameras
• Added the maxRange field which allows to set up the maximum range of the range-finder
• Added the wb_camera_get_max_range() function which allows to modify the maxRange field
• Replaced the wb_range_image_get_value() function (Deprecated) by the wb_range_image_get_depth() function which returns a linear scale (instead of logarithmic)
• Added semantic validation of the node structure when loading/importing .wbt/.vrml files
• Fixed problem with Webots random number generator: sensor noise (lookupTables) is now deterministic (until now only the physics noise was deterministic)
• Fixed buffering of mouse move events for 3D navigation in the main window
• Fixed Webots crash when project directories contain space characters (Mac+Linux)
• Fixed compilation problems if Webots installation directory contains space characters (Mac+Linux)
• Fixed: right after after having been inserted with the Scene Tree, USE nodes of geometrical primitives appear 10x smaller than their corresponding DEF nodes
• Under Linux, fixed crash while trying to run a 64 bit controller with a 32 bit webots
• Added "Open Recent" menu to find more easily recently opened .wbt files
• Removed "author" and "constructor" fields from all Solid (and derived) nodes to simplify Scene Tree
• Added a default values to every "name" field
• Robotstadium: was completely relooked: lighting, shininess, textures, colors, etc. were changed (the physics was not modified)
• Added new "force-3d" type of TouchSensor that computes and returns the 3d-vector of the force applied to the sensor
• Fixed the handling of the CLASSPATH environment variable in order to match the Sun standard
• Removed the black and white Camera type
• Changed Webots code for sensor/actuator simulation to double-precision floating point numbers.
  All the APIs were already using double precision and therefore they remain 100% unchanged (but some devices may return values with a higher accuracy).
  The physics simulation remains mainly unchanged.
• Replaced buggy --batch option with new --minimize option (all platforms)
• Added command line options (--minimize, --mode, --version) to Windows and Mac platforms
• Fixed wrong positions of "minStop" and "maxStop" of Servos (thanks to Jesse)
• Made the "position" field of Servo nodes editable: this allows to specify initial positions/posture that differs from the zero positions/posture
(The meaning of the "translation" and "rotation" fields of the Servo have slightly changed: now they represent the initial (instead of the current) coordinate system transformation of the Servo.)

Hi,

I am pleased to announce we just publicly released Webots 6.2.beta1. This is a major upgrade which introduces a much better 3D rendering engine (based on OGRE 3D) among other features and bug fixes. You can download it from here: http://www.cyberbotics.com/beta/ (Linux i386, Linux x86-64, Mac OS X and Windows versions). Please send us your feedback about this beta version as we could not test it on every combination of operating systems, CPU, graphics cards, etc. This will help us prepare the final release of Webots 6.2.0.

Here is a copy of the change log since version 6.1.5:

Released on November 19th (revision 4280)

• Added compatibility with Windows 7: fixed printf() redirection in Webots console and freeze when using Build/Compile/Clean buttons
• Removed unused API functions: wb_supervisor_field_get_mf_rotation(), wb_supervisor_field_set_mf_rotation(), wb_supervisor_field_get_mf_bool() and wb_supervisor_field_set_mf_bool()
• Removed obsolete Gripper node (mainly used in old Khepera worlds)
• Fixed texture path problem with controller rendered camera images
• Removed the useless "display" field from the Camera node
• Fixed crash and improved the behavior of the find/replace dialog with respect to multiple buffers
• Migrated the Webots rendering system to OGRE 3D (Object-Oriented Graphics Rendering Engine)
• Modified the rendering of the lights and of the materials in order to fit better the VRML specifications
• Improved the lighting model; the ambient, diffuse and specular fields can behave differently
• Improved the rendering of every worlds (mainly the worlds of the guided tour and of robotstadium)
• Added support for texturing the Cone, the Cylinder and the Sphere primitives
• Added a subdivision field to the Cone primitive
• Improved the TextureTransform node (supported in every primitive able to have a texture)
• Improved the rendering abilities
• Improved the shadows; shadows are now volumetric, transparent, additive, and are casted from and received to any renderable object
• Improved the transparent object management (the render of transparent object is no more dependent on their position in the scene tree but are sorted according to their center)
• Added the "Wireframe" rendering mode which allows to display the segments of the renderable primitives
• Added the experimental "High Quality" rendering mode which allow to render the diffuse and specular lights per-pixel instead of per-vertex
• Refactored the Preferences dialog box and the View menu
• Added the lineScale field to the WorldInfo node in order to control the length of every arbitrary-sized lines
• Improved the anti-aliasing of the Camera primitive which is now computed by the hardware
• Moved the far clipping plane to infinity
• Removed the far field from the Viewpoint and the Camera nodes
• Removed the wb_camera_get_far() function
• Improved the range-finder cameras
• Improved significantly the performances of the range-finder cameras
• Added the maxRange field which allows to set up the maximum range of the range-finder
• Added the wb_camera_get_max_range() function which allows to modify the maxRange field
• Replaced the wb_range_image_get_value() function (Deprecated) by the wb_range_image_get_depth() function which returns a linear scale (instead of logarithmic)
• Added semantic validation of the node structure when loading/importing .wbt/.vrml files
• Fixed problem with Webots random number generator: sensor noise (lookupTables) is now deterministic (until now only the physics noise was deterministic)
• Fixed buffering of mouse move events for 3D navigation in the main window
• Fixed Webots crash when project directories contain space characters (Mac+Linux)
• Fixed compilation problems if Webots installation directory contains space characters (Mac+Linux)
• Fixed: right after after having been inserted with the Scene Tree, USE nodes of geometrical primitives appear 10x smaller than their corresponding DEF nodes
• Under Linux, fixed crash while trying to run a 64 bit controller with a 32 bit webots
• Added "Open Recent" menu to find more easily recently opened .wbt files
• Removed "author" and "constructor" fields from all Solid (and derived) nodes to simplify Scene Tree
• Added a default values to every "name" field
• Robotstadium: was completely relooked: lighting, shininess, textures, colors, etc. were changed (the physics was not modified)
• Added new "force-3d" type of TouchSensor that computes and returns the 3d-vector of the force applied to the sensor
• Fixed the handling of the CLASSPATH environment variable in order to match the Sun standard
• Removed the black and white Camera type
• Changed Webots code for sensor/actuator simulation to double-precision floating point numbers.
  All the APIs were already using double precision and therefore they remain 100% unchanged (but some devices may return values with a higher accuracy).
  The physics simulation remains mainly unchanged.
• Replaced buggy --batch option with new --minimize option (all platforms)
• Added command line options (--minimize, --mode, --version) to Windows and Mac platforms
• Fixed wrong positions of "minStop" and "maxStop" of Servos (thanks to Jesse)
• Made the "position" field of Servo nodes editable: this allows to specify initial positions/posture that differs from the zero positions/posture
(The meaning of the "translation" and "rotation" fields of the Servo have slightly changed: now they represent the initial (instead of the current) coordinate system transformation of the Servo.)

• Added the "Wireframe" rendering mode which allows to display the segments of the renderable primitives
• Added the experimental "High Quality" rendering mode which allow to render the diffuse and specular lights per-pixel instead of per-vertex
• Refactored the Preferences dialog box and the View menu
• Added the lineScale field to the WorldInfo node in order to control the length of every arbitrary-sized lines
• Improved the anti-aliasing of the Camera primitive which is now computed by the hardware
• Moved the far clipping plane to infinity
• Removed the far field from the Viewpoint and the Camera nodes
• Removed the wb_camera_get_far() function
• Improved the range-finder cameras
• Improved significantly the performances of the range-finder cameras
• Added the maxRange field which allows to set up the maximum range of the range-finder
• Added the wb_camera_get_max_range() function which allows to modify the maxRange field
• Replaced the wb_range_image_get_value() function (Deprecated) by the wb_range_image_get_depth() function which returns a linear scale (instead of logarithmic)
• Added semantic validation of the node structure when loading/importing .wbt/.vrml files
• Fixed problem with Webots random number generator: sensor noise (lookupTables) is now deterministic (until now only the physics noise was deterministic)
• Fixed buffering of mouse move events for 3D navigation in the main window
• Fixed Webots crash when project directories contain space characters (Mac+Linux)
• Fixed compilation problems if Webots installation directory contains space characters (Mac+Linux)
• Fixed: right after after having been inserted with the Scene Tree, USE nodes of geometrical primitives appear 10x smaller than their corresponding DEF nodes
• Under Linux, fixed crash while trying to run a 64 bit controller with a 32 bit webots
• Added "Open Recent" menu to find more easily recently opened .wbt files
• Removed "author" and "constructor" fields from all Solid (and derived) nodes to simplify Scene Tree
• Added a default values to every "name" field
• Robotstadium: was completely relooked: lighting, shininess, textures, colors, etc. were changed (the physics was not modified)
• Added new "force-3d" type of TouchSensor that computes and returns the 3d-vector of the force applied to the sensor
• Fixed the handling of the CLASSPATH environment variable in order to match the Sun standard
• Removed the black and white Camera type
• Changed Webots code for sensor/actuator simulation to double-precision floating point numbers.
  All the APIs were already using double precision and therefore they remain 100% unchanged (but some devices may return values with a higher accuracy).
  The physics simulation remains mainly unchanged.
• Replaced buggy --batch option with new --minimize option (all platforms)
• Added command line options (--minimize, --mode, --version) to Windows and Mac platforms
• Fixed wrong positions of "minStop" and "maxStop" of Servos (thanks to Jesse)
• Made the "position" field of Servo nodes editable: this allows to specify initial positions/posture that differs from the zero positions/posture
(The meaning of the "translation" and "rotation" fields of the Servo have slightly changed: now they represent the initial (instead of the current) coordinate system transformation of the Servo.)

major upgrade which introduces a much better 3D rendering engine (based on OGRE
3D) among other features and bug fixes. You can download it from here:
http://www.cyberbotics.com/beta/ (Linux i386, Linux x86-64, Mac OS X and Windows
versions). Please send us your feedback about this beta version as we could not
test it on every combination of operating systems, CPU, graphics cards, etc.
This will help us prepare the final release of Webots 6.2.0.

WorldInfo.runRealTime FALSE

normal mode = ~83x
fast mode = -2.92e+... (not logical, maybe because is too fast. The
world is too simple)

webots/projects/robots/khepera/worlds/khepera.wbt

WorldInfo.runRealTime FALSE

normal mode = ~65x
fast mode = ~760x

With these models the graphics card is working ok. I think the problem
has something to do with reading back the image, like in my model when
capturing the image (using the camera) or the following example:

webots/projects/robots/khepera/worlds/khepera_gripper_camera.wbt


WorldInfo.runRealTime FALSE

normal mode = ~1.50x
fast mode = ~1.58x

*Hello,
Yes, I did. I also noticed a strange behavior;
1) if disable the display of the camera (to run faster simulation batches), in my webots's world => differential_wheels/Camera.display to FALSE, Camera.windowPosition to 0 0 and Camera.pixelSize to 0 according to:*
/"Dear Rufino,
There is indeed a problem in the documentation. Please set Camera.display to FALSE, Camera.windowPositi /
/on to 0 0 and Camera.pixelSize to 0 and that will disable the display of the camera (but still compute the image off screen, so that your controller should behave the same). We are working on fixing this in the next release of Webots, currently under preparation.
Cheers,
-Olivier"
/
*Results: - Webots screen mode => works slow ~ 1x (runRealTime to FALSE)
- Webots fast mode => works slow ~ 1x (runRealTime to FALSE)
- Webtos batch mode => doesn't work, terminal output:*
$ webots --batch khepera_matlab_green_walls.wbt
An invalid memory reference occured.
Please report this error to http://www.cyberbotics.com/bug/
This will help us improving this software. Thank you.
Quitting...
*if disable the display of the camera (to run faster simulation batches), in my webots's world => differential_wheels/Camera.display to FALSE, Camera.windowPosition to -1 -1 and Camera.pixelSize to 0:*
*Results: - Webots screen mode => works slow ~ 1x (runRealTime to FALSE)
- Webots fast mode => works slow ~ 1x (runRealTime to FALSE)
- Webtos batch mode => works slow.
*
*It looks like webots runs at ~ 1x simulation speed irrespective of runRealTime variable is set to FALSE (should run > 1x) or runRealTime to TRUE (should run ~ 1x). When before with an older graphics card (ATI Radeon HD 4550/PCI-E 2.0 512MB DDR3/64 bit) the simulation run ~ 3x in screen mode. I checked this by running the model and the /usr/local/webots/projects/robots/khepera/khepera.wbt demo world without using a camera device. And both show a huge increase in simulation speed > 1x. So it seems that the problem has to do with two things, the combination between the new ATI drivers and the new graphics card, and its interaction with webots camera interface. Is there anything I can do to fix this?
*
*Best regards,
Rufino*
when trying to run in 'batch mode', it doesn't work returning under webots's terminal this message:
The message shown above appears when in my webots world

 Hello Rufino,
Did you set WorldInfo.runRealTime to FALSE ?

Hi, I am designing a MSR robot in webots.I designed a single module
which is uploaded on youtube (
http://www.youtube.com/watch?v=mzujGEMGeQw).In the model I am facing
the problem of rotating the middle shaft.I designed the shaft using
the servo node.Can anyone please help me ?

Hello,

It seems that you need to link your project with Webots libraries:
These libraries are located in the WEBOTS_HOME/lib directory:

For C code link with:

libController.so    (Linux)
libController.dylib (Mac)
Controller.dll      (Windows)

For C++ code add this (to the above):

libCppController.so    (Linux)
libCppController.dylib (Mac)
CppController.dll      (Windows)

Cheers,

Yvan

Hi!! congrats for this group.

I have a question.

Im trying to compile a program wich should use some webots options but it will
not be running as a webots controller.

I will explain better...

I have a NaoQi broker wich talks with webots thanks to naoqi but I need to
access to some devices that I cannot access with NaoQi (leds, accelerometer). I
can compile the program, I have no error messages when compilling but I have
some undefined references on my exe:

undefined symbol: wb_robot_init

I have the same problem if I use the c++ api:
undefined symbol: _ZN6webots5RobotC1Ev
undefined symbol: _ZN6webots5Robot16getAccelerometerERKSs

someone have any idea?

thanks.

*Hello,

Yes, I did. I also noticed a strange behavior;

1) if disable the display of the camera (to run faster simulation
batches), in my webots's world => differential_wheels/Camera.display to
FALSE, Camera.windowPosition to 0 0 and Camera.pixelSize to 0 according to:*

/"Dear Rufino,

There is indeed a problem in the documentation. Please set
Camera.display to FALSE, Camera.windowPositi /

/on to 0 0 and Camera.pixelSize to 0 and that will disable the display
of the camera (but still compute the image off screen, so that your
controller should behave the same). We are working on fixing this in the
next release of Webots, currently under preparation.

Cheers,

-Olivier"
/

*Results:  - Webots screen mode => works slow ~ 1x (runRealTime to FALSE)
               -  Webots fast mode => works slow ~ 1x (runRealTime to FALSE)
               - Webtos batch mode => doesn't work, terminal output:*

                                  $ webots --batch
khepera_matlab_green_walls.wbt
                                     An invalid memory reference occured.
                                     Please report this error to
http://www.cyberbotics.com/bug/
                                     This will help us improving this
software. Thank you.

                                      Quitting...

*if disable the display of the camera (to run faster simulation
batches), in my webots's world => differential_wheels/Camera.display to
FALSE, Camera.windowPosition to -1 -1 and Camera.pixelSize to 0:*

*Results: - Webots screen mode => works slow ~ 1x (runRealTime to FALSE)
               -  Webots fast mode => works slow ~ 1x (runRealTime to FALSE)
               - Webtos batch mode => works slow.
*

*It looks like webots runs at ~ 1x simulation speed irrespective of
runRealTime variable is set to FALSE (should run > 1x) or runRealTime to
TRUE (should run ~ 1x). When before with an older graphics card (ATI
Radeon HD 4550/PCI-E 2.0 512MB DDR3/64 bit) the simulation run ~ 3x in
screen mode. I checked this by running the model and the
/usr/local/webots/projects/robots/khepera/khepera.wbt demo world without
using a camera device. And both show a huge increase in simulation speed
  > 1x. So it seems that the problem has to do with two things, the
combination between the new ATI drivers and the new graphics card, and
its interaction with webots camera interface. Is there anything I can do
to fix this?
*

*Best regards,
Rufino*



when trying to run in 'batch mode', it doesn't work returning under
webots's terminal this message:

The message shown above appears when in my webots world

Hi,

I did. Everything seems to be working ok, except from webots simulation
(too slow ~ 1x), I run the 'glxgears' command with this output:

desktop:~$ glxgears
21168 frames in 5.0 seconds = 4233.527 FPS
20667 frames in 5.0 seconds = 4133.359 FPS
20592 frames in 5.0 seconds = 4118.335 FPS
19997 frames in 5.0 seconds = 3998.828 FPS

Thanks
Rufino

A few weeks ago my off-board graphics card broke down. Today, I installed a new graphics card (ATI Radeon HD 4550/PCI-E 2.0 512MB DDR3/64 bit). I am having the following problem: my simulation runs too slow ~ 1x, even slower than the on-board (not so good) graphics card. Also, with the old off-board card (x1550 256 MB) it reached speeds around 3x. All this is in debugging mode (no fast or batch mode). Any suggestions of how to solve this problem?

Hi,

Platform: Linux Ubuntu 8.04/ 64 bits; Webots v6.1.5; Matlab R2007b.

A few weeks ago my off-board graphics card broke down. Today, I
installed a new graphics card (ATI Radeon HD 4550/PCI-E 2.0 512MB
DDR3/64 bit). I am having the following problem: my simulation runs too
slow ~ 1x, even slower than the on-board (not so good) graphics card.
Also, with the old off-board card (x1550 256 MB) it reached speeds
around 3x. All this is in debugging mode (no fast or batch mode). Any
suggestions of how to solve this problem?

Hi guys,

I can only control 3 physical epucks by the remote control function in Webots
version 5.  If I set up connections with 5 or more epucks, they will lose
communication with Webots soon after starting to run. Do you know how many
epucks can be remotely controlled by Webots Version 6, and work well?  Any tips?
Thanks a lot!
