Display contact points all at once

[Mark01]

Hey guys, 

This should be fairly simple. 

I have a ball bouncing on a plane, I am finding the contact points but rather than displaying then one at a time as the ball bounces, I need them all together on a frame hold

I am transferring the Cd attribute from the ball to the plane to get the contact points. 

Then we are removing all ground geometry except the contact points

if (@Cd.g >= 0)
	removepoint(0,@ptnum);

the contact points appear frame by frame as the ball is bouncing. Any idea how to get them all to display at once?

 

So I guess I need to store the contact point somehow?

Hi,

this example shows you how you can get impact points after simulation with bullet solver. This method you can use with classic animation. Since you already managed to get the points just use solver sop only.

Thanks for the reply! 

i think it's even simpler than what you described. 

i am just trying to store all the color from the impact points on the ground. 

I assume this can be done with a sop solver and reading the previous frame but im not sure how?

you can use rest and alpha

Hmm, that doesn't seem to work, could you explain

Bring the attribute transfer into the solver rather before it
