Sketching Mesh Morphing

Mesh morphing is the gradual transformation of one mesh surface into another.This technique has been a lively topic of research for many years. Generating amorphing between two meshes basically consists of two main sub-problems: vertexcorrespondence and vertex path.This paper presents a novel interactive system for mesh morphing that is veryeasy to use. The user simply draws some freehand sketches on both source mesh andtarget mesh respectively to specify global-level correspondences by pairingmeaningful components to represent their high-level requirements. The user can alsouse brush to specify low-level vertex or line correspondences over local featureswithin a pair of corresponding components. Our system interpolates meshes by firstinterpolating between their compatible skeletons and then unfolding the interpolatedcomponent pieces from the intermediate skeleton. The approach explicitly considersthe shape interiors as well as the boundary and explicitly models interdependencebetween the mesh vertices relative to the skeleton. User control is greatly enhanced inour system and even an amateur can use it to design morphing with ease. Manyexperimental results have shown that our system can produce good morph sequencesthat maintain the distinctive features of the input models.
