介绍

TreeGenerator是由Nicolas Bonneel个人开发的树木建模软件，在植物的快速建模中有自己的特点。

其最大的特点是生成树的方式非常的简单，依据其设计理念，只需要大概36个参数的设置就可以在5分钟之内调节出需要的树木模型。

当前主要有两个版本可供使用：一个是 TreeGenerator v1.2，另一个是最新的TreeGenerator v2.0。

特点

- DXF, OBJ and 3DS export of your trees

- Handle texturing/UV coordinatesgeneration (not exported in .DXF fileformat)...

- Interactive control of all parameters ofeach branch level for reasonable tree complexity.

- Leaf designer : just draw the outline ofyour leaf, with the help of a leaf texture if you want, and TreeGeneratormeshes it automatically and place it all over the tree.

- Control leaf density and scale for eachbranch level

- Levels of detail changing the resolutionof your tree mesh, and billboard cloud feature

- Number of levels to increase your treecomplexity

- Random seed change to be able to generatelots of different trees from a same set of parameters

- Tree's structure stored in the exportedfile allow easy modifications (each leave and each branch are storedindependantly which allow redesigning your tree in your favourite modeler, anddoing some special effect with leaves like wind blow).

- A bark texture tiling utility allows youto make a bark texture tileable (shading removal, symetrization...).

Branches parameters are :

- Length, Radius, Radius decrease withlength (linear and exponential terms)

- Twisting (radius and frequency)

- Bending

- Noise

- Resolution ( number of vertices along andaround the branch)

- Number of children and children positionning

- Leaves density

- Texture

...

Some parameters can be inherited from theparent's branch as a percentage of the parent value of the parameter.
