hi writer

I am new in Graphics programming and written simply as you have mentioned. My Project is working fine , but i have two questions.

1. when u said to reverse the velocity of the particle. what does that mean.
( as in my program
A. i have calculated the distance between the last Position (before collide) and next supposed position (without collision) and that distance is considered as speed at a particular frame of time and that is applied for calculating next position after PLANE hit)

2. i need some solution in which plane is also translating, rotating, or scaling..

I am new in Posting Problems…
If u didn’t get my problem, i can again explain in detail.

FYI the Flex 3 project is easily converted to build in Flashdevelop.

Just create a new AS3 Flashdevelop project file in the “\ParticleCollisionTest\src” folder and add “ParticleCollisionTest\src_pv” to the project classpath.

Be sure to also add an output SWF filename to the project settings.

That’s the kind of class that will give birth to many applications. Well done!

import com.lee.papervision.LeeCamera3D;
import com.lee.papervision.PlaneHorizontal;
import com.lee.papervision.Util3D;

where i can find those classes?

REALLY impressive. Very nice. Excellent framerate!! And yes, as far as I can tell from your explanation, the bounce math sounds right to me; abs(input_angle - normal) should equal abs(output_angle - normal).
