[SOLVED] How to increase FPS of a scene including more than 20000 tetrahedral mesh

[Suwan]

Hello,

I made a scene which consists of 23460 tetrahedral mesh.
I included “sofa/examples/Objects/TetrahedronSetTopology.xml”
It shows a simulation of collision detection/respsonse and cutting operation.

Then I got severe frame drops below 20 FPS while simulating it.
It’s worse in case of collision detection/respsonse of objects than just displaying them.

I want to improve FPS of the scene to 60 FPS.
Could someone please let me know how I can achieve my goal?

I would appreciate any ideas.

Hi @suwan,

A good point would be to create a surface mesh with lower resolution dedicated to the collision detection. So that the physics would still run on the 23460 tetrahedral mesh, while the collision computation would be done on a coarser mesh.

Another solution would be to use GPU implementation.

Do you have any scene with meshes that we could test ?
If this is confidential, you can still contact me in PM.

Best regards,

Hugo
