Three.js is an open-source JavaScript 3D library developed in the mrdoob/three.js project for assembling and rendering procedural scenes in browser applications, including Fable 51 Worlds, Human Atlas, browser FPS worlds, CAD workspaces, and physics games. It creates scenes containing cameras, geometry, materials, meshes, and animations, with WebGL and WebGPU renderers and SVG and CSS3D renderers available as addons. Its official site and repository provide documentation, examples, tools, an editor, community resources, and a JavaScript module distribution.

A browser-based first-person shooter built with Three.js r180 and WebGL2. It uses procedurally generated textures, meshes, animations, and Web Audio synthesis rather than external art or sound files; its systems include a market-street world with enterable interiors, custom physics and character movement, procedural weapons and ballistics, GPU visual effects, navmesh-based enemy AI with perception and cover behavior, and a DOM/CSS HUD. The repository also provides a development and testing harness: headless-Chromium screenshot capture, isolated reproducible shotsets with pixel-diff gating, scripted playtesting, and a gameplay profiler that reports frame-time distributions and attributes hitches to per-frame WebGL program compilation. The project is run with npm and has Three.js as its only runtime dependency.

Box3D is an open-source 3D physics engine for games, written in portable C17. It provides rigid-body simulation with collision detection, continuous collision detection, contact events, convex hulls, capsules, spheres, triangle meshes, height fields, multiple shapes per body, collision filtering, ray and shape casts, overlap queries, sensors, and a character mover. Its physics system includes a robust Soft Step rigid-body solver, continuous physics, island-based sleeping, and revolute, prismatic, distance, motor, weld, and wheel joints with limits, motors, springs, friction, and force events. The data-oriented system uses multithreading and SSE2 or Neon SIMD, supports cross-platform determinism and recording and replay, and is optimized for large piles of bodies. The core library has no dependencies beyond the C runtime and libm on Unix, can be integrated with CMake as the box3d::box3d target, and builds on Windows, Linux, macOS, and WebAssembly; its samples use sokol and Dear ImGui.

An interactive skillshot visual-effects sandbox built with Three.js, Vite, and hand-written GLSL. It provides seven abilities and five aiming modes, with keyboard-armed targeting indicators that follow the mouse before the user clicks to fire. The documented abilities use procedural animated effects such as molten ground and burning blades, a ring of tentacles emerging from a rift, an electrical sphere rising from a containment platform, stone formations along a cast line, and constructed gates or rings. The video describes it as a workbench for designing game abilities while they are animated, using procedural geometry, GLSL, and GPU particles with live adjustment against a paused frame.

Jolt Physics is an open-source, multicore-friendly C++ rigid-body physics and collision-detection library for games and VR applications. It simulates rigid bodies with continuous collision detection across shapes such as spheres, boxes, capsules, convex hulls, meshes, and terrain; supports constraints including fixed, hinge, slider, gear, pulley, spline, and six-degrees-of-freedom joints; and provides ray casting, shape queries, broad-phase detection, sensors, vehicles, ragdolls, soft bodies, and buoyancy. Its design supports concurrent physics-data access, background loading and unloading of bodies, collision queries running alongside simulation, and deterministic simulation by replicating inputs. The project also provides bindings for several languages.
