This program renders a sphereical world. In it you can get into the car and drive around or get out and look at the trees.
Each type of tree has it's transform matrix generated at launch and then for collusion detection every time a movement key is pressed it checks if the new camera location would be inside of the trees. It does this by if the camera falls inside of the bounding box. When driving the car a flag is changed and the car's model transform is swapped to be locked with the camera.
