A collection of single-file C libraries by Philip Rideout, in the stb style, focused primarily on graphics tasks like procedural mesh generation, orbit camera control, and streamline triangulation. Each library ships as one self-contained, documented header, with a few extras covering HTTP requests, LRU file caching, easing functions, and 2D broad-phase collision detection.

Use cases

• generate sphere and rounded cuboid meshes in C
• add orbit or pan-and-zoom camera controls to a 3D viewer
• triangulate wide lines and curves for rendering
• generate parametric surfaces like cylinders and tori in C
• pack circles into hierarchical bubble diagrams
• make simple HTTP requests in C without heavy dependencies
• get easing functions for animations in C

When to choose

• you want drop-in, single-header C libraries with no build system or dependency overhead
• you need CPU-side procedural geometry (spheres, rounded boxes, parametric shapes) for OpenGL/Vulkan-style rendering
• you are building a small 3D viewer or tool and need orbit/pan/zoom camera behavior
• you prefer small, readable, well-blogged utilities over large frameworks

When to avoid

• you need a full rendering engine, scene graph, or GPU-side framework rather than focused CPU-side utilities
• you require strong maintenance guarantees - some sub-libraries are explicitly unmaintained (e.g., par_msquares)
• you need C++-idiomatic APIs with classes, templates, or package-manager integration
