View Full Version : floating point textures and gluBuild2DMipmaps

Can I use gluBuild2DMipmaps and gluScaleImage with floating point textures in the GL_FLOAT_RGB32_NV or GL_RGBA_FLOAT32_ATI format?

I'm pretty sure you can't mipmap floating point textures.

Mipmapping them should work, at least with the ATI float textures, not with the NV ones. But the glu functions will most likely not work, you have to use the generate mipmap extension or generate them yourself...
