Collision Sets and Events Accuracy

mattdavis

Hi,

I am doing some simulation of programs that use a physical touch sensing tool.

I have setup a collision set between the tool and the object it is touching, and events to change the touch inputs so that the program will run, but the results are very inaccurate which makes it a bit hard to verify if the program is working or if its just the simulation.

What is the best way to make this accurate, i have set it to run in time slice mode with the smallest step size available, but in testing it on a pipe (cylindrical 3d object, the pipe gets rendered as a having lots of corners instead of a smooth shape whilst the simulation is running and i think the collision set works on this also. Is there a way to make it render the shapes properly (i dont mind if it runs alot slower)?

Hi Matt,

To increase the graphics detail used for collision detection, you will have to re-import the geometry with only the "Fine" level enabled in Options/Graphics/Geometry. (The collision detector will use the coarsest level available).
You might also want to decrease the simulation speed to less than 100%, otherwise the graphics might not be able to keep up.

regards,
Johannes

Thanks for that...

works perfectly now. (uses about twice as much processor, but it was only using 40% before so i didnt have to slow it down any).
