PfPOV has been updated with cubic splines support.
Normally when exporting with PfPOV, any object that doesn't have a surface produces a simple array of vectors (as for example used in the
animation tutorial).
That feature has its limits: Only the actual positions of the vertices are used which makes it cumbersome to create smooth animations.
With cubic splines positions are extrapolated and it finds "good" positions between the actual vertices.
I got tired of having to copy and paste the array into a spline declaration and fiddle about so I added spline support directly in PfPOV.
Result: Making an animation like this, (including the crappy modeling ;-) ) takes about 5 minutes...
The model:
The camera is translated to a spline based on the line (drawn by the line tool) in the maze. The animation is 100 images, but there's only 56 vertices in the line...
