Abstract: A great deal of research has been devoted to generating 3D tree shapes by simulating tree growth to obtain realistic yet imaginary tree shapes. In order to display an actual scene in 3D computer graphics, 3D tree shapes of actual trees are necessary. Currently, despite considerable research on 3D shape reconstruction of objects from their silhouettes, the existing methods have so far been unable to handel complicated shape objects like trees whose silhouettes have a lot of occlusions. In this paper, we propose an algorithm for reconstructing 3D tree shapes based on fractal geometry, and show some experimental results.!33
