Replacement for GL_SIGNED_RGBA_NV
Is there is a replacement for this? Something that is in core GL perhaps.
I'm using shaders so I can do some manipulation but it would cost instructions.
I could use floating point format but it would cause a slowdown. I think I will go for floating point for the moment.
I have the following from a demo code
glTexImage3D(GL_TEXTURE_3D, 0, GL_SIGNED_RGBA_NV, size, size, size, 0, GL_RGBA, GL_BYTE, data);
