The Rigid Body solver simulates the motion and collisions of objects as if they were hard, solid objects (as opposed to other types of simulated objects such as fluids, cloth, and soft bodies). Rigid Body Dynamics is often abbreviated as RBD. RBD objects can be active or passive. Active objects are affected by forces and collisions.

This solver is a union of two different rigid body engines, the RBD engine and the Bullet engine. The RBD engine uses volumes and is useful for complicated, deforming, stacked, geometry. The Bullet engine offers simpler collision shapes and is suitable for fast, large-scale simulations.

May 27, 2019 · In this beginner Houdini tutorial Theo walks you through a basic dynamics setup for making a cube fall onto the floor, then a setup for shattering the cube. ...

In Rigids V, we'll create a series of blasts whose shape and position are based off of a dynamic laser gunfire simulation! We'll design the shape of the explosion at each laser bolt impact by controlling the sources of the new rigid body debris, particles, streamers, and smoke.

4 days ago · Rigid Body Dynamics (RBDs) in Houdini have gone through a lot of changes in the last decade, and one side effect of all that rapid development is that there’s a lot of confusing legacy stuff left over in both Houdini and in outdated educational materials that I keep seeing new users get stymied by. SideFX have done quite a lot in recent years ...

May 10, 2023 · In this course, I'll show how to create rigid body simulations in Houdini. In this first part, we'll consider concepts such as "packed objects" and the basic setup of the simulations in...

Feb 16, 2018 · Applied Houdini is here with a spectacular new version of Rigids III - Vehicle deformation! In this lesson we'll tackle everything that goes into making high quality vehicle destruction, from deforming metal to spinning axles.

RBD, more commonly known as Rigid Body Dynamics, is a system inside Houdini. This system allows for the motion, fracturing, and collision of objects to be handled within solvers. As well as a combination with SOP tools.

Oct 18, 2019 · Rigid Body Solver in Houdini. In a destruction tutorial video I posted on my Youtube channel, I demonstrate how to setup a simple RBD (rigid body dynamics) simulation for a destruction scene. I use the Rigid Body solver to calculate the collision dynamics between the objects in the scene.

New Houdini Procedural: RBD LOP which transforms high-resolution geometry at render time based on a point cloud, similar to the Transform Pieces SOP. This can be used to efficiently cache and render large RBD simulations in USD.
