Dynamic crumpling and tearing of surfaces is now available using the cloth solver in Houdini 10. This allows for plastic deformations which go a step beyond what rigid body dynamics can offer you. When rigid objects react dynamically there is something unnatural about the way they are not affected by a forceful impact. Plastic deformations give a more natural look to even the simplest colliding objects.
Another new feature in Houdinis cloth solver is the ability to cut cloth dynamically. It is always fun when you find a new use for an existing tool. Using the cloth solver in Houdini 10 for plastic deformations and tearing will help VFX artists create those awesome destruction sequences we have come to expect out of our summer blockbusters.
