I was wondering, little off the shader topic, but only a little.....

....could you create a grass sowing system based on an image of the world map, something like this?

say blue would be grass, white shrubbs etc...

Just that this could allow for fast delivery of grass or other shrubs etc...especially considering your Waving Grass. I am really impressed with EA Sports Tiger Woods 2004, its grass is lovely The only way I think they could have done it is with the method I suggest above, the grass is dense on certain parts of the course filling the rough areas perfectly, I wondered if there was a way to achieve this with your grass example?

If someone can point me in the right direction...
