Cheap Trees

These trees are not ultra-realistic, but they're easy on memory.

The leaves are made of three parts. One part is a series of cones with no bottoms that have been jittered. The cones near the bottom open downward and the cones near the top open upward. This fills out the leaves when viewed from above or below. The next part is made up of flat ellipses arranged like an asterisk. This fills out the leaves when viewed from the side. The last part is a blob that fits inside the other parts. This just gives the leaves a little more body.


The trunk is just a tapered cylindar with a little jitter. Some more tapered cylindars can be used as branches if you feel you need them. Make sure that all the branches fit nicely inside the leaves. The whole tree is 6 meters tall in this example. The leaves must be saved as one object and the bark as another.
