Re: [osg-users] TexGen limitations

The mistery is solved. On Nvidia cards, a maximum of 4 Multitexture Units are allowed. you can simply query this value by calling glGetIntegerv(GL_MAX_TEXTURE_UNITS, iUnits); So it looks like using TexGen is therefore limited to the lowest 4 Textureunits, which is not very logical. Actually

Re: [osg-users] TexGen limitations

Hi Daniel, I doubt your test methodology is correct. For recent years I've beeen often using TexGen on stage 6 and 7. On many GeForces and some Radeons and even Intel HD 3000. I think TexGen used at 0-7 is very common and thus your observation must be wrong... Perhaps you read the Microsoft

Re: [osg-users] TexGen limitations

Hi Wojtek, would you mind doing the simple test with the sample program osgspotlight and the modifications I documented? I wonder if you get the same different results as soon as you use texture units from 4 and above. Cheers, Daniel -- Read this topic online here:

Re: [osg-users] TexGen limitations

Hi Daniel, I confirm your observation. I, however, do not agree that its a TexGen problem. Frankly I do not know what it is, and I had no time to investigate, but I think its maybe relate to TexEnv settings. I only made a following test: I zeroed a spotlight texture (memset( image-data(), 0,

Re: [osg-users] TexGen limitations

Interesting. So could this be a bug in osg? Did you try to query GL_MAX_TEXTURE_UNITS and check if it says 4 ? I wonder if this value does not only mean maximum number of multitexture units, but also that only the lowest 4 units are capable of beeing used for multitexturing! This would kind

Re: [osg-users] Using PBOs for Texture Upload

Hi, I investigated this a bit more. I believe I have arrived at the bottleneck. I stepped through the BufferObject code (which ImageStream uses via the derived class PixelBufferObject) and found that every time the dirty() method is called on osg::Image, in the osg::Texture that uses this

Hi Rebecca, 3.2.1 hasn't been cancelled, just delayed as the window I had for getting it out disappeared I was back concentrating on project work. One of the issues I had with getting 3.2.1 out is that I had practically no feedback on testing of the 3.2.1-rc1, I can't make a release without

[osg-users] Using the OSG Max Exporter Plugin - Biped Animation

Hi all, is there a possibility to export a character using biped animation? When I try to export animation in that way, only biped parts are animated, but not the character. Also, I think, that biped data should not be exported at all as a part of exported geometry...   Regards,

Hi Gianni, I haven't had time to look at the model but as quick response based on your description I'd say it's an issue with coarsed grained depth sorting that the OSG does to workaround around the deficiencies of depth buffer based rendering that one does with standard OpenGL. This is a very
