To ensure that the body is not pulled apart the mesh used has to have shared vertices.I have been developing physics engines for simulating fracturing soft bodies for a long time (the first primitive one was over ten years ago) and my latest iteration is the first of mine that is the result of original research. The Softbody Soft BodyĪ softbody is a 3D soft body.

You may have to do a trial and error on the above parameters to get the effect you want.

As an example look at the triangular facets in the diagram below If not the soft body will rip apart along unshared vertices. The number of vertices used and the need to check their positions and velocities each time step means that the number of soft bodies can be restricted to one, two or possibly three.Īny triangular facet belonging to a mesh used as the basis for a soft body must share its vertices with any adjacent facet. LimitationsĪ deformation of a body can only be shown if there are sufficient vertices to produce the deformation.

See How to Use The Physics' Engines for an overall view of setting up and using the three plugins. First a number of limitations need to be considered, followed by some aspects particular to soft bodies and then some examples. There are three soft bodies you can create, the three dimensional softbody, the two dimensional cloth and the one dimensional rope. Out of the three plugins available with Babylon.js soft bodies are only available using Ammo.js.

In terms of physics' engines a soft body is a body that can have its shape deformed by interactions with other bodies or forces within the physics world.
