This new year of 2001 I've decided to help some people (graphists) in their job.... nice isn't it ? So, I've made this software : a Tree Generator, based on some simple algorithms : Each branch has 3 children branches which are rotated from a certain angle from their parent, which are scaled (reduced) and translated (along their parent direction) ... and this is processed how many times we'd like (here, limited to 9 times ... but that's enough for a very good looking tree) so it (try to) makes reallistic trees.
In other way, it's just called a L-Parser algorithm.
Once the tree is created, you can export it (DXF format) and use it in most of 3D softwares (ALL Autodesk ones : Autocad, 3DSMax...and lots of other softwares)
Now, I've added leaves generation, a random ability for each parameter and a better previewing quality... Tree Generator is licensed as shareware, the cost of the registered verison is $15 and full size of the download is 0.51 MB. You may download a free version of Tree Generator by following download link at Free Download section of this page. Tree Generator is developed or distributed by Nicolas BONNEEL and is listed under 3d software.
