Tree Generator 1.2 650kb
 
Tree Generator is a software for creating 3D trees. You can then export them in a .dxf file into your favorite raytracer, or include it in your best nature scenes.
 The tree can be exported in .DXF format (for Autocad, 3DSMax.... and most 3D modelers and raytracers) and in .TGF format (Tree Generator File : save all parameters - Only in registered version). There are 4 different 'rendering' methods : 
- Lines : for slow computers : it only shows the "skeleton" of the tree.
- Wireframe : It shows the "skin" of the tree.
- Shaded : It shows the "colored skin" of the tree. It can be slow if there are lots of polygons.
- Shaded+Wireframe : It helps you see polygons shape and the shape of the tree (can be slow too). Moreover, you can add a colored background using "Options"->"Display options"
