Hello everyone. I am currently working on a project involving terrains. I am wondering how the xyz coordinates of a height map or a mesh grid can be...
Hello Victor, I don't know why the ElevationGrid has a disabled "height" field. But you can change the elevation of the whole grid by modifying the ...
Hello Victor, ... ??? No, an ElevationGrid is a _flat_ surface, it can be used only as a _flat_ ground ... So the best is to use a IndexedFaceSet if you need a...
Hello Paolo, I did this once a long time ago so my memories are inaccurate: So it was more or less like that: 1. Recompile a "debug" version/configuration of...
Hello there Yvan, I just wanted to say thanks for everything. The information has been really useful. My supervisor was able to find (I think that you had...
Hello, I have problem with path for the image used as a texture. When I just the local path and the name of the image Webots looks up at the globally installed...
Hi Victor, You can generate a texture for an IndexedFaceSet from most of the 3D modeling software (like Blender, ArtOfIllusion, 3D StudioMax, Maya). You should...
And I forgot to say that the texture image should be a square image (not rectangle) with a width and height being a power of 2 (i.e., 32, 64, 128, 256, 1024,...

Hello Claudio, You can pan/tilt a Camera by putting it under the control of two Servos. (One Servo for pan and another one for tilt.) Here is a VRML example...
Hello Hiroshi, This is quite complex ! You need to know a bit of physics, of vector maths, and of ODE programming. You will have to create a physics plugin for...
Hi, can I set a robot's position to a given (x,y,z,roll,pith,yaw) at run-time? I can do that using the supervisor, but I would like to do it with the robot's...
