Getting Started

Hello Cube

Minimal scene: one box, one light, one camera.

Hello Animation

Rotate, bounce, and scale a cube using clock.delta.

Orbit Controls

Click and drag to orbit, scroll to zoom.

Geometry

Geometry Types

14 built-in geometry types displayed in a 4-column grid.

Geometry Parameters

Adjust segment count on Sphere, Torus, Cylinder, and Cone.

Wireframe

Six geometry types rendered in wireframe mode.

Custom Geometry

Build geometry from raw vertex data using Attribute and Geometry.

Materials

Material Types

Three spheres showing BasicMaterial, LambertMaterial, and ToonMaterial side by side.

Toon Shading

Four ToonMaterial spheres with different colors showing cel/stepped shading.

Flat vs Gouraud

Two spheres: flat shading (one color per face) vs Gouraud shading (per-vertex, interpolated).

Points Material

Point rendering mode with adjustable point radius.

Lights

Light Types

Compare Directional, Point, Spot, and Hemisphere lights on a sphere and ground plane.

Hemisphere Light

HemisphereLight blends a sky color and ground color based on the surface normal direction.

Point Lights

Three colored PointLights orbiting a TorusKnot at different radii and speeds.

Camera

Orthographic Camera

Parallel projection: objects stay the same size regardless of depth.

Perspective Camera

Frustum projection with adjustable field of view in degrees (same as THREE.js).

Scene Graph

Scene Hierarchy

Sun-planet-moon system: nested Group pivots compose parent transforms automatically.

Group Transforms

Nested Groups compose transforms: outer rotates, inner scales, meshes inherit both.

Animation

Animation Basics

Manual position/rotation/scale animation driven by Clock.delta - no keyframes needed.

Keyframe Animation

AnimationClip with VectorTracks drives position and scale. action.timeScale controls playback speed.

Animation Blending

Two clips on the same Animator: crossFadeFrom switches smoothly between Bounce and Spin.

Textures

Alpha Test

Glass texture with binary alpha transparency.

Canvas Texture

Procedural patterns drawn on an offscreen canvas and applied as a texture.

Texture Mapping

UV mapping on a box using TextureLoader with LambertMaterial.

Repeat Wrapping

Demonstrates Wrapping.Repeat with adjustable UV tiling.

Interactive

Raycaster

Move the mouse over the grid to highlight cubes via ray-object intersection.

Click Events

Click an object to select it. Click again to deselect.

Helpers

Scene Helpers

AxesHelper, GridHelper, and BoxHelper visualize orientation and object bounds.

Performance

Scene Stress Test

Configurable mesh grid to stress traversal, fog, sorting, and texture sampling.

Rasterizer Benchmark

Single sphere with adjustable subdivisions and material modes to isolate rasterizer throughput.

Frustum Culling Test

Large grid of objects with camera aimed at one corner to test frustum culling effectiveness.

Multi-Light Stress Test

Measure lighting cost by adjusting the number of point lights in the scene.

Point Cloud Stress Test

Stress test the PointRasterizer with large vertex counts.

Overdraw Stress Test

Overlapping translucent planes to measure overdraw and transparency cost.

Scene Hierarchy Depth

Deep nested scene graph to test matrix propagation cost.

Resolution Scaling Test

Measure how rendering cost scales with canvas resolution.

Voxel Chunk Stress Test

Minecraft-style voxel chunks testing geometry merging vs individual meshes.

Mixed Complexity Scene

Heterogeneous scene with varied geometry, materials, and shading modes.
