Systems, methods, and computer readable media to improve the animation capabilities of a computer system are described. Animation targets may be represented as a combination of a current animation pose and an incremental morph. The incremental morph may be represented as a series of non-zero weights, where each weight alters one of a predetermined number of target poses. Each target pose may be represented as a weighted difference with respect to a reference pose. Target poses may be stored in memory in a unique and beneficial manner. The disclosed manner permits the efficient retrieval of pose vertex data at run-time and may be especially efficient in systems that do not use, or have very little, cache memory.
