How to generate a meadow and a tree? Thanks greatly!

I am hurrying to generate a tree and a meadow to use in my scenery. Does anybody can give me some advice? Thanks greatly.

3D Studio Max? Maya? Milkshape 3D?


In fact, I hope to have such models so that I can read them into my program (using VC++ and OpenGL) so as to show them in my scenery. I know there are football(soccer) and car(porsche) models somebody has made, and anyone can read the model by a subroutine.

However, I know there is a algorithm to generate terrain. If there are no such models (meadow, tree), I hope someone can recommend some algorithms to me to generate such nature objects.
