Detailed Description

A class expressing a nonuniform scaling transformation.

The scaling is along arbitrary axes that are specified by PxMeshScale::rotation.

Note:

Negative scale values are supported for PxTriangleMeshGeometry with absolute values for each component within [PX_MIN_ABS_MESH_SCALE, PX_MAX_ABS_MESH_SCALE] range. Negative scale causes a reflection around the specified axis, in addition PhysX will flip the normals for mesh triangles when scale.x*scale.y*scale.z < 0.

Only positive scale values are supported for PxConvexMeshGeometry with values for each component within [PX_MIN_ABS_MESH_SCALE, PX_MAX_ABS_MESH_SCALE] range).
