◆ SB_estimate_transform()

void SB_estimate_transform	(	Object *	ob,
		float	lloc[3],
		float	lrot[3][3],
		float	lscale[3][3] )

extern

A precise position vector denoting the motion of the center of mass give a rotation/scale matrix using averaging method, that's why estimate and not calculate see: this is kind of reverse engineering: having to states of a point cloud and recover what happened our advantage here we know the identity of the vertex there are others methods giving other results.

Parameters

ob	Any object that can do soft-body e.g. mesh, lattice, curve.
lloc	Output of the calculated location (or NULL).
lrot	Output of the calculated rotation (or NULL).
lscale	Output for the calculated scale (or NULL).

For velocity & 2nd order stuff see: vcloud_estimate_transform_v3.
