[Colladamaya-updates] RE: Collada plug-in for Maya, May 3rd 2005

[Christian L. <cla...@fe...>]

Hello,

	Guillaume has implemented a first version of the skew/shear
import/export, and I've finished implementing the rigid body compound shape
transforms and bounding volumes. 

	The very latest version is available from:

Detailed changes:

	Shear/skew export/import. In Progress - Mantis #23. Without baked
matrices and since the shear part of the transform isn't exported, the child
transformed meshes are incorrect. Added direct export and import of the Maya
shear plug values. Found a simple way to do shear to skew by converting the
three factors independently. Skew to shear is more complex and involves
taking out of the skew matrix the rotation and scale factors until only the
shear factors are left.

	Physics: implemented per-shape transforms. Don't output unnecessary
identity transforms (e.g. translate of 0,0,0; rotate of 0 degrees).
	Fixed batch files, so that the mel scripts are copied in the right
directory (scripts/others) rather than scripts/unsupported.
	Physics: fixed bounding volume (sphere, cube) dimension computation.
Initially these were computed in world space... now, they are properly
computed in rigid-body space.

	Physics support: Added code to support new dynamic attributes, on
both rigid body and compound shape level. Using these attributes, it is now
possible to assign mass or density to compound shape elements. Likewise, it
also makes possible overriding the mass or density at the rigid body level,
and overriding the inertia tensor. Also added new standIn types (e.g. convex
hull, capsule, etc.) that can be specified at both the rigid body and shape
level. Some features are still missing: transform per shape, automatic
computation of bounding boxes at the rigid body level, etc.

Christian and Guillaume
