Xsi Flow polygons v2

Break polygon objects into polygons at runtime (scripted operator).
Developed & tested under Xsi 4.0

WARNING: this is an early prototype, it's VERY slow. Test it before using in production.

This operator prototype can be used to breakup objects into polygons, detaching only a specific amount of geometry and consequently preserving discontinuity angle.

The operator includes a procedural animation system, which can make the polygons fly away (it can be used to create polygonal explosions), flow object subcomponents around a center, ecc.

Every parameter is animatable!

The parameters:

Active - Enables / disables the operator.
Update - A trick used to force the operator to update on frame change.
Start - The animation start frame.
Nodes - The number of polygons to detach, which can be animated too!

Method -
1 (Reindexing along direction) - Detaches the polygons based on polygon positions on a particular axis.
2 (Reindexing using indexes) - Detaches the polygons based on the geometry polygon indexes.

Reindex_using_axis (applies only if Method = 1) -
0 = x / 1 = y / 2 = z
Reindex_using_direction (applies only if Method = 1) -
0 = goes from top to bottom / 1 = goes from bottom to top

Speed - The global Speed / Acceleration multiplier, a value of 0 completely stops Animation.
Position_Normal_Multiply - Multiplies the normal position by the speed value.
Position_XYZ_Multiply - Multiplies the polygon position by the speed value, in object space.
Rotation_XYZ_Multiply - Multiplies the polygon rotation by the speed value, in object space.

Global rotation - Rotates the polygons around the object center.
