PROBLEM TO BE SOLVED: To generate a preferred tree image having rich diversity by using processings that are made labor-saving, to some extent.SOLUTION: A feature designation process is performed in the order to designate features of a trunk and a branch, according to a kind of tree to be drawn. Then, a drawing process is performed under control of the designated features of the trunk and the branch, by repeating recursive operations based on restricted rules (e.g., trunking property, apical dominance property, and sun-seeking property of a branch) among rules utilizing characteristics of the tree and drawing the branchings of trunk and branches in the image. When the operations are performed for drawing branchings based on control and rules using the characteristics of the tree, random number additional processing is performed by adding a random number. |
