Abstract
We present a new method for user controlled morphing of two homeomorphic triangle meshes of arbitrary topology. In particular we focus on the problem of establishing a correspondence map be- tween source and target meshes. Our method employs the MAPS algorithm to parameterize both meshes over simple base domains and an additional harmonic map bringing the latter into corr espon- dence. To control the mapping the user specifies any number of feature pairs, which control the parameterizations produc ed by the MAPS algorithm. Additional controls are provided through a di- rect manipulation interface allowing the user to tune the ma pping between the base domains. We give several examples of æsthet- ically pleasing morphs which can be created in this manner with little user input. Additionally we demonstrate examples of tempo- ral and spatial control over the morph.
