I have a deforming triangle, whose vertices all move between t0 and t1.
I am shooting a ray toward the triangle. The ray doesn't hit the triangle at t0 or t1, but somewhere within that interval of time.
How do I calculate the exact point of intersection for the ray, and at what time (between t0 and t1) that the ray hits the triangle?
Here's an image that hopefully helps illustrate the question better:
