Hi. So the question is in the title. I have an arbitrary point in space inside a sphere, let it be point A. I need to sample a texture color at the surface point closest to my point A. Imagine a vector going from a center of a sphere to the surface through point A . I need to know the color where the vector hits the surface. My initial idea was to transform point A to spherical coordinates and have angles represent uv coordintes(mapped to 0-1 range). However, I can't seem to get it to work. Any help would be greatly appreciated!
