Mouse Train in OpenGL

Hi,

I am trying to bind an object to the PassiveMouseFunc

now I can get it to draw the shape. however when i move the mouse it creates a trail, I don't want a trail.

I am already using double buffering, is there a way to get rid of the trail?

this is what i am talking about

Thx

Issue a gl_clear() on the colorbuffer of your current backbuffer, then draw the object to said buffer and swap().

(You'd probably get better help in Game Development)

thx for the reply, but how do i do that? I posted in the Game Programming ,so mods can delete this.
