 SOFA implements a series of collision primitives called CollisionModel. A CollisionModel contains a list of same-type elements. It can be part of a list of CollisionModels or a hierarchy. Here is a list of them:
 
-- [pointcollisionmodel](./../PointCollisionModel)
-- [linecollisionmodel](./../LineCollisionModel)
-- [trianglecollisionmodel](./../TriangleCollisionModel)
-- [spherecollisionmodel](./../SphereCollisionModel)
-- [cylindercollisionmodel](./../CylinderCollisionModel)
-- [cubecollisionmodel](./../CubeCollisionModel)
-- [raycollisionmodel](./../RayCollisionModel)
