Got a need for Trees? Greenworks Organic Software has 100 free trees from their XFrog linefor you available on the Autodesk Seek website. Thank Ken Pimentel for arranging this, and be sure to tell him you want more.
The trees are available on the Autodesk Seek website, "the online source for design and product specification".
Free of charge, these trees are botantically correct, and come in a variety of formats - you can use them in 3ds Max Design 2010, 3ds Max 2010 and Maya 2009. These are the same trees that have been used by high-end film houses such as Pixar, SONY Imageworks and have appeared in movies like "The Incredibles" and "War of the Worlds".
Each tree is a separate download, so it can take a little time to get them, and make sure you have plenty of diskspace, I downloaded the breadfruit tree, it's 26 MB zipped and 75 unzipped. I got 3 breadfruit trees in the download, they represent 3 different ages (young, medium and mature). These are handy if you have to show the planning department what the vegatation is going to look like when the project is completed and what it will look like when the trees reach their maximum height.
I haven't downloaded all of them (oh for the time and diskspace), but I will. Soon as I get a vacation.
Virtual Gardening is good for you. Try it out!
