I'm trying to define a Texture2DArray (Using OpenSceneGraph). However, whenever I set the texture format to a 32-bit floating point texture (eg. GL_RGBA32F_ARB, GL_LUMINANCE_ALPHA32F_ARB, etc), I keep getting OpenGL compile errors:
Warning: detected OpenGL error 'invalid enumerant' at StateSet::compileGLObejcts() compiling texture attribute
GL Error when compiling Texture2DArray
Does the "GL_EXT_texture_array" extension support floating-point texture arrays?
I have a Quadro 5000 with 260.19.21 NVIDIA driver.
