The Fast Drawing Of The Trees In The Virtual Plant Growth

Currently there are mainly the Fractal Systems and A son System etc. in many methods of computer fictitious plant's from drawing, including the tree drawing. Comparing with the Fractal System, other methods have not enough dynamic transform effect under external influence and third dimension are worse on the side of the tree drawing.I set up the model of the tree's growth structure according to the theory of trees self-similar growth in my text. And I found dynamic three -dimensional trees model by Iteration Function System according to analysis form and structure of trees, then realize the drawing of many tree quickly by the way of saving spot from the view, the texture and the basic surface normal. It appears fully that there are some merit on speed of drawing and small saving-space. Finally I draw the tree realistic from scene illumination, projection, texture and Collision Detection aspect, thus realize the trees scene roams.
