Hi, I'm developing an application using VTP as the base. Application is something like virtual city modelling. Used numerous shape files to create multi...
hi, from the few infos in your post, i do not think that using a fbo or pbo will solve your problem. libmini is already using vtx caches. the problem is that...
Hi Stefan, Thanks for the suggestion. Yes, I'm trying to reduce the memory footprint. However I have already implemented LOD for building. Problem is like, if...
... yes, this is a good approach. from far away a buidling can be represented with just a colored scaled box. even more than reducing the geometric complexity,...
Hi, I have created a VTP terrain model using a DTED and Tiff image. Model has been created using TILESET. Now for a specific area, inside the terrain, I have...
Hello All, Whenever we derive DEM automatically using photogrammteric techniques, we get DSM. Does VTP has any features to derive bare-earth model from...
In Enviro, I have been able to add a detailed image overlay to my terrain with 50% transparency (original terrain texture shows through overlay) by using a png...
I was able to solve my own problem, but I still wonder if there's a more efficient way. I can change the transparency of the image overlay by going through...
Hello, I am encountering an issue on the shadows in Enviro. It seems that any osg file I have is becoming completely black once I switch shadows on. With...

Hello, I notice that the Enviro function: "Play animation to disk as a series of images" only saves black images. I am trying to change "LocationDlg.cpp" and...

Hello all, I had a new strange problem with VTP and Windows 7 (new 64 bit machine): VTBuilder, CManager and Enviro do not start, and they report: ...
... Roberto, VTP works very well on my Windows 7 PCs (1 Xeon workstation, 1 core i5 laptop, 1 Parallels virtual machine in Mountain Lion on an iMac core i7,...
After around a year away from the VTP, I recently needed to build and test a fresh shiny set of binaries in order to give a VTP demo. For that, I built a VTP...
Hi Roberto, I also use VTP standard distribution (also the new 1.2) on a Win7-64 machine and it works. I always install it within a personal folder (C.\GIS\)...

Hi Alberto, it works. :) Thanks Roberto ... [Non-text portions of this message have been removed]...
Dear VTP Team, I am using VTP in a project and I found a peculiar problem when using shadows. When the shadow algorithm (which is supposed to render shadows of...
It's 1.8 years later, but i have a followup for this thread now. :) The slow forest rendering has bothered me also, for a long time. So, recently I worked on...
I have uploaded a new VTP release, version 1.3 (121210). It has been over a year since the last release, mostly due to my job at Google, but I've had some time...
Hi Jijith, It's difficult to guess what might be happening, because there is some interaction between the VTP's shadow code and your own code, but we don't ...
Hi Ben I am attaching the snap shot of the application before and after applying shadows (Ephemeris > shadows). I have shown the code-snippets responsible for...
... Jijith, As Ben says you need to update to the latest version of VTP before going any further. Making direct calls to openGL functions is not a good idea...
Lars, Sorry for delay, but I am going through older list message and so: Do you still have the OSG file which doesn't shadow correctly? I am assuming there is...
Hi Roger Thank you for this inputs. I am working on a generic OpenGL based User Interface for a set of OpenGL based applications. Not all of these applications...

There have been reports that even with the latest fixed VTBuilder, it may still draw elevation layers flipped vertically, on some machines. It does not appear...

Ben and Davide, I have the vertical flip problem using the VTBuilder "Elevation" > "Render to Bitmap" function. Instead, the "Export to..." have not problems....
