Detailed Description

A class expressing a nonuniform scaling transformation.

The scaling is along arbitrary axes that are specified by PxMeshScale::rotation. Specifically, PxMeshScale::rotation describes the rotation from the scaling-axes frame to the mesh-local frame, i.e. PxMeshScale::rotation.rotate(v) transforms the coordinates of vertex v from the mesh-local frame to the scaling-axes frame.

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).
