Given there is triangle: V in 3D space that transforms over time t -> t1 to V1, and a static point P is somewhere in 3d space, how can I determine if P ever collides with V, and if so at what value of t?

The transformation of the triangle from V -> V1 over time means the vertices Va,Vb,Vc each move linearly and independently in three dimensions to new vertex positions V1a,V1b,V1c. (Sorry about my notation). There are no constraints on the transformation of the vertices with respect to each other. The triangles at V and V1 representing the transformation may be any 2 triangles in 3d space.

Given there is triangle: V in 3D space with vertices (v1,v2,v3) that transforms over time t0 -> t1 to V1, and a static point P is somewhere in 3d space, how can I determine if P ever collides with V, and if so at what value of t?
