We present an interactive tree modeling and deformation system that supports an efficient collision detection and avoidance using a bounding volume hierarchy of sweep surfaces. Starting with conventional tree models given as meshes, we convert them into ...

There is growing worldwide interest in the use of 3-PG model as tool for forest management. It requires only readily available site, climatic data and genetic characteristics of trees as inputs and predicts the time-course of stand development on a ...

We propose a simple and effective modeling method for creating animation opening flowers. Because the detailed geometry of flower petals is defined by a base shape deformation, we simulate the development of petal based on deformation and emulate its ...

Some very impressive results have been obtained in the past few years in plants and trees image synthesis. Some algorithms are largely based on the irregularity and fuzziness of the objects, and use fractals, graftals or particle systems. Others focus ...
