WebApr 26, 2024 · First we trace the plane with the capsule line (ray). Then we determine the closest point on the triangle to the trace point. The reference point is the closest point on the capsule line to that. We will place the sphere on the reference point and do a normal triangle – sphere intersection test as usual.
