DMM: Testing glass material
The box is a glass material type with some changes to the basic material property. This is my simulation with dmm plugin for 3ds max. As you can see, the material could have been more realistic if i had increased the number of tetrahedrons while creating the dmm object. If the scene had materials and lighting it would have been more pleasant. As the box breaks, you will see individual tets coming off. This is finite element method for you. :)
