Abstract:
The present invention discloses a sketch-based shape maintaining tree transformation animation method, comprising: creating a three-dimensional tree model; representing the three-dimensional tree model in the form of a skeleton and a cluster of leaves; selecting an angle of interest, detecting the step (2) canopy silhouette of the 3D tree model, and the transformation animation target canopy silhouette is drawn on the sketch, and the crown silhouette of the 3D tree model is gradually transformed into a transformation animation target crown silhouette, and the crown of the 3D tree model is the transformation of the silhouette is transmitted to the branches to obtain a smooth transformation process of the trees; the transformation process of the crown silhouette and the branches is recorded frame by frame, and the tree transformation animation of the shape is obtained. The invention maintains tree topological consistency and canopy morphological significance, and also provides an intuitive three-dimensional tree editing operation, which can effectively edit a three-dimensional tree model by simply drawing a simple sketch.
