In what cases do we need to handle interpenetration of triangles? Can we divide them into smaller, non-overlapping triangles to avoid interpenetration?

We could potentially do this, but this gets really expensive really quickly... especially when rendering millions of triangles to a screen every second. When it comes to both rasterizing and ray tracing triangles, it is a lot easier to simply sample one or multiple discrete points within the pixel to determine how much area each triangle occupies. This was discussed later in the lecture.
