The ivy grows from one single root following different forces: a primary growth direction (the weighted average of previous growth directions), a random influence, an adhesion force towards other objects, an up-vector imitating the phototropy of plants, and finally gravity. This simple scheme reveals that the goal was not to provide a biological simulation of growing ivy but rather a simple approach to producing complex and convincing vegetation that adapts to an existing scene. The ivy generator imports and exports obj+mtl files

一款很棒的藤蔓植物生成软件，只要先将想添加藤蔓的3D物体导出为obj+mtl格式，然后再将其导入到Ivy Generator中就可以轻松的生成真实的藤蔓植物包裹效果。下载文件中的ivy_generator_Textures.zip 为树叶材质贴图文件集。
