The tree pole and leaves are the 2 factors of 3D model to construct the trees .There are many modeling methods, but some modeling’s fidelity and efficiency are low, and others are difficult to simultaneously solve two problems existing in consideration .This study puts forward the way of constructing any crooked or smooth connec-tion tree poles based on a little characteristic parameters and control variables , and the way of leaves analogy meth-od based on leaves image processing which is fine intelligent and express easily .The method provid...
