Asset loading for 3D models, textures, HDR environments, and progress tracking in Three.js. \n \n Supports multiple formats: GLTF/GLB (primary), OBJ+MTL, FBX, STL, PLY, and HDR/EXR environment maps with optional DRACO geometry and KTX2 texture compression \n LoadingManager coordinates multiple loaders with progress callbacks, onLoad/onError handlers, and unified asset tracking across the scene \n Texture configuration covers wrapping modes, filtering, anisotropic sharpening, color space manageme

Keyframe, skeletal, and morph target animation system for Three.js objects and models. \n \n Supports four animation track types: number, vector, quaternion, and color keyframes with linear, smooth, and discrete interpolation modes \n AnimationMixer plays clips on objects with full playback control: play, stop, pause, speed adjustment, weight-based blending, and fade in/out transitions \n Skeletal animation via bone manipulation, bone attachments, and GLTF model loading with automatic clip disco

High-performance 3D web applications with Three.js WebGL/WebGPU rendering. \n \n Covers scene setup, geometries, materials (PBR, standard, custom shaders), lights, cameras, and animation systems \n Supports asset loading (GLTF, FBX, OBJ), textures, post-processing effects (bloom, SSAO, SSR), and raycasting for interaction \n Includes performance optimization techniques: instancing, LOD, batching, frustum culling, and WebGPU backend support \n Enables specialized workflows: physics simulations, V

Complete Three.js lighting system covering all light types, shadows, and environment-based illumination. \n \n Supports six light types (ambient, hemisphere, directional, point, spot, rect area) with detailed shadow configuration for each, including map size, camera frustum, bias tuning, and softness controls \n Includes environment lighting via HDR and cube textures with PMREM generation, light probes for ambient capture, and contact shadows as a fast alternative \n Provides three production-re

Comprehensive texture loading, configuration, and application for Three.js scenes. \n \n Covers texture types including basic, data, canvas, video, and compressed formats, with loaders for each \n Supports environment mapping via cube textures, HDR (RGBE/EXR), and equirectangular conversion with PMREM \n Includes UV mapping, texture atlasing, wrapping modes, filtering, mipmaps, and render targets for dynamic effects \n Provides PBR material texture setup (color, normal, roughness, metalness, AO,

Screen-space visual effects pipeline with bloom, depth-of-field, anti-aliasing, and custom shader composition. \n \n EffectComposer chains multiple rendering passes (bloom, SSAO, DOF, film grain, vignette, color grading) in sequence, with each pass reading the previous output \n Supports 15+ built-in effects including UnrealBloom, BokehPass (depth-of-field), FXAA/SMAA anti-aliasing, OutlinePass, and GlitchPass \n Custom ShaderPass enables writing fragment shaders for effects like chromatic aberr

Mouse and touch input handling, raycasting, camera controls, and object selection for Three.js scenes. \n \n Supports five camera control types: OrbitControls (orbit around target), FlyControls (free flight), FirstPersonControls (WASD movement), PointerLockControls (locked pointer FPS), and MapControls (2D map-style panning) \n Raycasting enables click detection, hover effects, and object selection with detailed intersection data including distance, UV coordinates, and face information \n Includ

Essential Three.js scene setup, cameras, renderers, and object hierarchies for 3D web graphics. \n \n Covers scene creation, three camera types (Perspective, Orthographic, Array), renderer configuration with tone mapping and shadow support, and the Object3D hierarchy system \n Includes right-handed coordinate system, transform operations (position, rotation, scale, quaternions), and local vs. world space conversions \n Provides math utilities for Vector3, Matrix4, Quaternion, Euler angles, and C
