Plane faces main View

[jaylocco]

Hi, I am making a landscape full of trees.In order to minimizes the program, I intend to add a vertical plane with a tree image and later clone it to several trees and scatter them.The thing is, how to make every each of them to always rotate on its position and face our view. so that they will seem like 3d trees. Or are there any better ways to do it?
Thanks in advance..

You can use billboarding for this.

tree = viz.add('tree.jpg')

quad = viz.addTexQuad()
quad.texture(tree)
quad.billboard(viz.BILLBOARD_YAXIS)
