Interact with .obj file properly?

Post by zhy149 »

Hello, I found some .obj files online and just import them to coppeliasim directly, but it doesn't seem I can grasp them, is there any setting I should modify to successfully interact with .obj files just like pure shapes?
Thank you!

Keep in mind that random shapes will perform very poorly when simulated with a physics engine (slow, and not stable). Try to use primitive shapes or convex shapes instead (or a compound of primitive or convex shapes): you can still use the original shape for the visual part, but use a simplified representation of it in a hidden layer, e.g.:

Code: Select all

simplifiedDynamicShape --> originalStaticShape
Read more about this in the design considerations on building a dynamics simulatiuon

Cheers
