Simple tree 3d model. Created in Blender 2.58.1. In archive available two .blend files, one from 2.58.1 with fully configured scene(for Blender Internal render) and from 2.49 with only tree base.
I found this post to be very helpful and informative. For those who are looking for further discussion on the matter, 먹튀검증순위 is a great resource to continue learning.
Thanks a lot.
-edit- Based on this model, I modified and rendered some images for use as billboards in my project. The tree images I rendered can be found here: http://graphicslearning.com/downloads/tree-01-cc0/
