Hello, I have been trying to load and read a texture using CUDA. I have been trying to understand the API for a week now and there are some explanations about the API I really don’t understand. I am trying to read an image from a 3 channel RGB file using the opencv lib and load the image as a textu…

The fundamental issue here seems to be confusion about the texture type. It’s evident from your code that you intend to read individual bytes (i.e. individual uchar color channels) from the texture. In that case, you want the texture type to be uchar not uchar4. When I make the following change…
