How to make collision with our own obj model

[ghost]

Hi,

Could you please provide an example on how to make collision with our own obj model ? from the file "ClothCollisionDemo.cpp" I tried to replace the torus obj file with the "armadillo" obj file but the cloth still collide with the torus object shape even tough it is not loaded.

Thank you.

The problem is that in line 266 a torus collisison object is created:

https://github.com/InteractiveComputerGraphics/PositionBasedDynamics/blob/master/Demos/DistanceFieldDemos/ClothCollisionDemo.cpp#L266

Instead of cd.addCollisionTorus() you should use cd.addCubicSDFCollisionObject()

Hope that helps.

Thank you for the info, I am trying to understand how to fill the function argument "GridPtr sdf". I just need to spend some time on the demo of scene loader it looks like it uses the function.

Try with this code...
