Pheromone Texture

Hi im developing an ant colony simulation and i need to map a pheromone array (int)to basic primative shapes that make up the environment, this map will have to be updated regularly and be turned on and off.

Im just starting to think about how to do this, i presume that i make some sort of texture from the pheromones array (might have a pheromone array for each primative shape) and map this to the shape every game loop.??

Does this sound ok?? Any opinions on better ways??

Thanks

How I do my radar HUD is just have a seperate TransformGroup for each blip. These are all children to the radar TG itself so turning on/off is a breeze.

Will.
