The mesh needn't be auto-generated, I've been tinkering with a script that would
permit the use of control points that would allow an existing mesh to undergo
various transformations. The idea was to allow the user to specify a control
point or groups of points, specify their effect radius, and specify a
transformation for each. The points within the radius would be transformed,
taking into account the effect of distance from that control point and other
control points.
Simple testing indicates that it would be troublesome from a parsing standpoint,
since to do this it requires that every affected point in the mesh definition be
replaced with an expression that yields the modified vector. I've been meaning
to finish writing C program that will insert the expressions, which will make
animating my wings models easier, but I haven't gotten around to it yet.
I do want to stress that it is very possible to animate a mesh2 in POV - so far
I've only used the divide and conquer method, but what I described above will
also work.
