Provide a special traversal function that samples both with interpolation between the two
When path tracing randomly select an interpolation value to use for a full sample
The above only works for linear movement, though. For nonlinear interframe motion or rotation the animation can be broken up into "steps" (a step including a "from" and "to" bvh) and a certain and consistent number of samples can be taken along each step.

confirm that interpolating triangles and bounds positions between two BVHs is valid.
