agh ss. Scenegraph: heirarchical (sometimes even spatial partitioning) tree that holds rotation information and entity links. think of a minitature one as applied to a skeleton based player model. the rotations are heirarchical and can be applied for the hands by simply traversing down the tree (whole body -> torso -> shoulder -> elbow -> wrist), applying all rotations as necessary to render the hand or represent the hand vertices in world space.
Col, maybe in a while, I want to implement higher paced game s for a bit >:) besides this game will rock, provided I get off my lazy ass and finish the collision detection functions and get to work on implementing constrained rigid body dynamcs.
