-	*** point-edge distance constraint
-	***	point-triangle distance constraint
-	*** edge-edge distance constraint
-	*** dihedral bending constraint
-	*** isometric bending constraint
-	*** volume constraint
-	*** shape matching
-	*** FEM-based PBD (2D & 3D)
-	*** strain-based dynamics (2D & 3D)
-	** Fluids:
-	*** position-based fluids 
-	** Rigid bodies:
-	*** ball joint
-	*** ball-on-line-joint
-	*** hinge joint
-	*** universal joint
