Soft Body Simulation This is a quick exploration of soft body simulation. I’m interested in simple, procedural methods for deforming meshes in response to their collision with other objects, specifically, character meshes made of jelly (slimes!). My research is focused on medical robotics. Now, one of my main tasks is the soft-body simulation. For my purpose, I use Gazebo9 and the DART physics engine. They both were successfully compiled from the source. Thus, I have the ability to launch the Gazebo simulator with the DART core support. But I don't know how to add deformable contact.

Volumetric Soft Body Simulation - Blender Foundation. Elastic deformation is an essential component of animation pipelines. Volumetric soft body simulation can be used to capture the complex details of muscle and skin, e.g. Volume preservation under collision/compression. 537k members in the Simulated community. A subreddit for all things computer generated simulations!
There are two main methods to control the soft body effect:
Goal - Soft body Goal acts like a pin on a chosen set of vertices; controlling how much of an effect soft body has on them.
With Goal fully active (1.0), the object will act like any regular animated object (no soft body effect). When setting Goal to 0.0, the object is only influenced by physical laws. By setting Goal values between 0.0 and 1.0, you can blend between having the object affected only by the animation system, and having the object affected only by the soft body effect.
Goal also serves as a memory, to make sure soft objects don't deform too much, ending up in the non-soft animated shape.
Using the Vertex Group weight system, you can define a Goal weight per vertex. To make this look more natural, spring forces can be defined to control how far vertices can move from their original position.
Springs - The Edge Spring Stiffness defines how much edges try to keep their original sizes. For example, by adding diagonal edges within a cube, it will become stiffer (less 'jelly like'). By tweaking the E Stiff parameter, objects can be set to try to, more or less, keep their original shape, but still move freely with dynamics.
When you enable the Soft Body effect on an object, it will always be simulated forward in time. Moving backwards in time or jumping in steps larger than 9 frames will reset the soft body back to its original position. Use the new TimeLine window playback to make tweaking Soft Body effects interactive.
Once you're satisfied with the simulation, you can Bake the simulation into a static animation system. A baked soft body plays back much more quickly, and is not dependent on simulation anymore.
It is recommended that you bake soft bodies when rendering animations, because the simulation doesn't work correctly for Motion Blur rendering, or for rendering in small chunks via a network render system.
Using Softbody for cloth simulation, especially with collision detection, is still in a testing stage. The current collision code requires improvements, which is scheduled for a later release. For more precise control over cloth simulation, we will also add special edge options in a later release. Currently, all edges have an equal effect on the soft body.
Since vertices in Soft Bodies are treated as particles, the options for Force fields and Deflectors apply for them as well. Please note that deflection (collisions) only work on non-deformed Meshes (not using hooks, armatures, lattices, etc). Check the release notes for more information.
In this cinema 4d tutorial, I will teach you how to create soft body & soft sphere animation. I take cube and cloner for creating stars. and use wind tool to push the sphere. after animation, I apply materials. dark gray material for stars and shine material for a sphere. so guys watch this video and learn every this. and you’ll get a quick intro to using Soft Body Dynamics & how to loop soft body dynamics to make an inflated rubber spheres
Intro to Soft Body Dynamics Tutorial Topics Include:
• Learn about soft body dynamics & it’s settings
• How to prepare your model for nice soft body dynamic simulations
• Using an object as a dynamic collider body
• Learning about Collision Shape options
• How to light and texture our spheres
If you have any questions about Soft Body Dynamics in Cinema 4D, be sure to post it in the comments section! Thanks for watching!
