Abstract:
In this search for a multi-variate version of Shoemake’s famous “slerp” function, two methods (using RBFs) have been implemented to continuously interpolate between several kinematic animation examples that differ along emotional input axes, such as happiness and fatigue. The extrinsic version was incorporated in the Swamped! interactive exhibit at SIGGRAPH 98, and the intrinsic version is used in the Millennium Motel (SIGGRAPH 99).
