[osg-users] Does OSG support ES2.0?

2013-01-04 Thread Paul Heraty
Hi, According to the 3.0 release notes, OSG introduces support for OpenGL ES 1.1, OpenGL ES 2.0. I'm using OSG 3.1.1, and I have built an application which works fine when I compile OSG to use OpenGL. It's a pretty simple app that reads in a textured 3DS model and displays it. However, when

OSG core works from the box what doesn't work from the box is osgText and other things that require the user to include his own shader to make work things. I have code that replaces the estandard stats handler with one 100% compatible with GLES 2.0 BUT it's not something that we can include in OSG

Hello all, I have an osg project that uses shaders to write float32 values representing temperatures to my framebuffer texture. I would like insert a CUDA or OpenCL kernel to take those temperature values in the framebuffer and reinterpret them as colors based on various sensor effects. My

[osg-users] Custom culling that works with shaders

2013-01-04 Thread Glenn Waldron
Robert et al., The topic of culling vis-a-vis shaders has come up a few times recently. The issue is: if you transform or emit vertices in a vertex, geometry, or tessellation shader, the new position information is not available to OSG's culling mechanism. This may result in visible geometry

osg Text is really easy to make it work with ogl, you have to use a shaders that is inherited by the osgText node that can read from texture and that's pretty much all. The other errors... well openGL extension is not supported will be probably because it needs some qualifier that it's not
