It seems like my lighting is off. However - all tests pass.
The code is on github here: github.com/twistdroach/raytracer-c
One thing that is interesting is that in my MATERIAL_lighting function - where we subtract light position from the point where the ray intersected the sphere to find the light vector, if i reverse the subtraction I get something that is different and very close to correct, but not correct....and - this makes all the material tests fail, so I'm sure that's not it.
Anyway - not really expecting anyone to sift through a bunch of C, but really just wondering if anyone has any troubleshooting tips or intuitively recognized a bug that would create the above image.
Thanks for any help anyone is able to provide - I will update if I figure it out....
