1. draws the los sphere. (light blue)
2. draws radar sphere. (green)
3. draws weapon range sphere, or cylinder, if using cylinder targeting. (red)
4. draws the hit sphere. (white)
it has a lot of chat commands to choose which spheres to draw, their render mode(lines, points, quads, polygons), and to draw for only selected units, or every unit in view.
it uses my new sphere drawing function, it allows choosing the render mode, number of subdivisions, and more.
it is good for testing stuff without having to hit 'b'.
i will release it soon.
