Interacting with Deformable Objects - Isaac Lab Tutorial 4 (Basics)

This tutorial, part two of interacting with objects, focuses on deformable objects in Isaac Lab. It introduces:

Finite Element Method (FEM) – Used to simulate soft bodies that deform under external forces and collisions.
Creating Deformable Objects – Using deformable_object and wrapping it around mesh_cubit_configuration to define attributes like Poisson’s ratio and Young’s modulus for deformation properties.
State Representation – Unlike rigid bodies, deformable objects are represented by nodal positions and velocities, which are updated in the simulation buffer.
Applying Randomization & Motion – Adjusting positions and orientations using quaternion operations for efficiency.
Kinematic Control – Modifying vertex positions to create motion, constraining specific vertices to explicitly control their behavior.
Updating the Simulation Buffer – Using write_nodal_state_to_sim to ensure accurate initialization before stepping the simulation.

By the end, viewers learn how to spawn, reset, control, and simulate deformable objects in Isaac Lab.
