SpeedTree is a special computer program that makes pretend trees for movies and video games.
Imagine you want to make a very realistic tree that will be in a video game or a movie. You could try to draw each leaf and branch by hand, but that would take a very long time. Plus, it might not look very good because you may not know how trees grow and look like in real life. To make it easier, you can use SpeedTree.
SpeedTree can create trees that look like real trees because it knows how trees grow and what they look like in real life. You just have to tell SpeedTree what kind of tree you want to make, and then it will use all its knowledge to make a 3D model of that tree. A 3D model is like a fake version of the tree that you can see from different angles.
After you have your 3D model tree, you can change how it looks by changing things like its size, shape, and color of its leaves. This can all be done without having to make the tree from scratch again. Once you are happy with how the tree looks, you can use it in your video game or movie.
Overall, SpeedTree is a computer program that can create very realistic 3D trees for video games and movies. It makes things easier and faster for people who want to create trees without having to draw every single detail themselves.
