FCL is a C++ library for performing proximity queries on pairs of geometric models composed of triangles. It supports collision detection, distance computation, tolerance verification, and continuous collision detection with optional contact information.

Use cases

• detect whether two 3D meshes overlap
• compute minimum distance between geometric models
• check if two moving objects collide during motion
• verify two models are separated by a tolerance distance
• get contact points and normals from collisions
• perform collision checks on octrees from octomap
• collision checking for robotics motion planning

When to choose

• you need fast collision or distance queries between triangle meshes or primitive shapes in C++
• you need continuous collision detection for moving models
• you're building robotics, physics simulation, or game collision systems
• you need octree-based collision checks with octomap integration

When to avoid

• you need a full physics engine with dynamics and response forces
• you want a high-level game engine rather than a geometry library
• you need GPU-accelerated broad-phase collision for massive scenes
• you work outside C++ and can't bind to a native library
