void SoftNodeDesc::get_joint_transform | ( | SAA_Scene * | scene, |

Extracts the transform on the indicated Soft node, as appropriate for a joint in an animated character, and applies it to the indicated node.
This is different from get_transform() in that it does not respect the _transform_type flag, and it does not consider the relative transforms within the egg file. more added functionality: now fills in components of anim (EffXfmSAnim) class (masad).

SAA_Elem * SoftNodeDesc::get_model | ( | ) | const |
