Hi there,
I just want to make an interest effect: my mouse will do moving in a circle, and follow my mouse i want there
is a blue “light” moves with the circle’s edge.
I saw this effect on some products. I dont know how to program the effect and whether the blue “light” is an
OPENGL light or something else(maybe it is just a picture).
Now i want to konw if this effect can be implemented with the OpenGL light? if yes, how to do the following:
- show a blue “light” in a very small area (ie, in rect(0,0,10,10))
- rotate the “light” around a circle’s center.
I also want to know if there are any easy methods to make this?
Thanks!
