## What it is
NoCol is a C++ 'anti-collision' trajectories finder that simulates moving objects (like balls) finding paths that avoid collisions. It renders an interactive visual simulation with zoom, pan, and playback controls.

## Use cases
- find collision-free trajectories for moving objects
- visualize anti-collision path planning
- explore trajectory optimization demos
- simulate balls avoiding each other
- learn about motion planning algorithms

## When to choose
- you need a visual demo of collision-avoiding trajectory search
- you want a C++ codebase to study motion planning
- you need an interactive sandbox for anti-collision simulations

## When to avoid
- you need production-grade robot path planning
- you require a library API rather than a standalone demo app
- you need multi-agent planning with real-world constraints

## Facets
- artifact type: application
- maturity: maintenance
- function: simulation, graphics, game-engine
- domain: simulation, graphics
- platform: cpp, cross-platform
- tags: trajectory-finding, anti-collision, physics-simulation, visualization, algorithms, desktop
