-  * Plant shape is entirely defined by algorithm
+L Systems are the standard approach to modelling and rendering plants with computer graphics. However there are some problems with them:
-  * Geometric complexity is slow to compute and render
-  * Somewhat difficult to control in an artistic sense
-This is an alternative method to the standard approach of rendering L Systems, where we can still define the topology of a plant by an algorithm, but the structural shape is defined by the texture images used as components of the plant.
+  * The plant's shape is entirely defined by an algorithm
+  * It's somewhat difficult to control in an artistic sense, particularly the way that branches are formed.
+  * Geometric complexity is slow to compute and render - it would be nice to be able to deal with some of the complexity in premade textures.
-This also allows us to put much more detail in the textures, and build plants out of fewer components.
