I have defined a type texture, but it seems I cannot use Tex3D() to do texture fetch. Then I checked the texture_fetch_function.h and found no function definition for 3 channel operation, just for 1,2,4 channel. I also checked the channel_descriptor.h, no definition for 3 neither.
So why CUDA doesn’t support 3 channels in texture? Do I need to use a type each time? That would lead to larger memory burden. Is there anybody can help?
