Hello everyone,
I have just a quick question. I wanted to make sure I ask so I don't forget as it's on my to do list. I can't seem to find out how to get the closest point on a disk. I have tried to find papers that cover this topic but to no avail.
If someone could guide me in the right direction it would help a lot! I already have Sphere, Tube, and Rectangle area lights.
I have a great set of math skills but I don't know how to apply it in this scenario, or have any tools that can help me calculate the closest point.
Thank you for your time!
