3D Simulation / Physics Website
Simulation pages demonstrate behavior over time. They are strongest when the motion itself teaches the concept.
- Best use case
- Technical portfolios, education, science, and playful demos.
- Recommended stack
- React Three Fiber + Custom math + Physics library later
When to use it
Use it when physical behavior, wave motion, orbital movement, or particles make the concept clearer.
When not to use it
Avoid it when the animation is only decorative and simpler CSS or 2D Canvas would work.

Performance risks
- Unbounded physics can become nondeterministic and hard to debug.
- Too many bodies or collisions can hurt mobile performance.
Recommended approach
Begin with deterministic custom math, then add Rapier or another physics engine only when collisions are core to the product.
