Hi. Thanks for the info. I'm now using shaders to process depth: 1) vertex: http://goo.gl/G9ehmB 2) fragment: http://goo.gl/bAutb1 As you see, I'm trying to output depth texture in world space using 'vmi' (view matrix inverse) which I apply later in the 2nd pass. vmi setup: http://goo.gl/n3A84N However, when I start the program, it prints 2 errors: 1) Cannot assign between Uniform types dmat4 or mat4 and int at: uniform->set(osg::Matrix::inverse(pass1LightDepthSRTTCamera->getViewMatrix())); call 2) Warning: detected OpenGL error 'invalid operation' at After Renderer::compile at: mat4 modelMatrix = vmi * gl_ModelViewMatrix;
I took the uniform setup code from osgUtil::SceneView: http://goo.gl/6OvdLr So I really don't understand what I'm doing wrong. Any help?
