Hi people!

While taking a closer look to the motionblur in megapov, I regonized that a
vertex-motionblur is possible.
All examples working only with transforms, such as translate, rotate, scale...

I've started to write a universal PovScript to handle a syntax, which is very
similar to the mesh2 syntax that generates the motionblur bases on geomagnetic
information from two frames.

The syntax for the geometry looks like this:
#declare Vertex_Vectors=array[1140][3]
{
 {0.0750842,-1.98293,4.51802},
 {0.106474,-1.58801,4.71834},
.......
#declare Normal_Vectors=array[1140][3]
{
 {-0.996115,0.0880451,-0.00146716},
 {-0.996944,0.0780921,0.00226744},
.......
#declare Uv_Vectors=array[1140][2]
{
 {0.447334,0.909562},
 {0.447334,0.909562},
.......

If you already familiar with the mesh2 syntax, you'll see the similarities.
I've already start to write a script for 3DS-MAX to export animated geometry, so
that it cam be rendered with motionblur in MegaPov.

I'm still working on it, but I'll think, I can share a working version in the
next two weeks.

The video shows a "running box", animated with MAX and was exported by my first
script and rendered with MepaPov
