A method is presented for representing botanical trees, given three-dimensional points and connections~ Limbs are modeled as generalized cylinders whose axes are space curves that interpolate the points A free-form sur~ce connects branching limbs. "'Blobby'" techniques are used to model the tree trunk as a series of non-circular cross sections. Bark is simulated with a bump map digitized from real world bark; leaves are textures mapped onto simple surface~ CR Categories and Subject Descriptors:doi:10.1145/325334.325249 dblp:conf/siggraph/Bloomenthal85 fatcat:xestk7gstncr5duylquxz6wukm
