   Help with texture generation
  I want to generate an image based of a transformed quad, the camera angle, and voxel data.What I had in mind was having a "skip pattern" for each pixel of the image. The skip pattern would have an x, y, and z element. The idea is that based on the quad transformation and camera angle I could check the voxel data at the skip pattern point for each pixel in the image to see if there is a renderable voxel at the skip pattern point.It's sort of like ray casting I guess. I want to essentially shoot a ray, while checking for data at fixed points.What I'm having problems with is determining how I should generate the skip pattern based off the quad transformation and camera transformation.Any help would be appreciated, thanks.
