Could you build this?
Partial Basic soft-body bouncy visual demos can be vibe-coded in Three.js or WebGL, but an accurate, stable dynamic soft-body physics engine requires advanced computational mechanics.
What it would actually take: A robust soft-body engine utilizes Position Based Dynamics (PBD) or Extended PBD (XPBD) or Finite Element Methods (FEM) written in C++, Rust, or WGSL/Compute Shaders. The hard parts include collision detection between deforming volumetric meshes, volume conservation constraints, and preventing numerical explosions under extreme stress. Developing this requires specialized knowledge in applied mathematics, numerical analysis, and real-time graphics simulation.
Discussion
20 comments analyzed.
Competitors mentioned: Other soft-body simulation libraries, GPU shader-based physics (hair, cloth), Analytical soft-body solutions
Concerns raised: README appears AI-generated and not thoroughly reviewed, "Use freely" license validity unclear, Physics timestep behavior with variable frame rates, Potential aliasing errors if step rate below Nyquist limit, Simulation stability without fixed timestep accumulator pattern
Feature requests: Human anatomical model demo with weight maps, Better documentation of timestep handling, Demo showcase in README showing intended use cases
