Cel shading mimics the appearance of flat, hand-drawn textures with limited color gradients and often with bold outlines around 3D objects. This effect is achieved by using: Toon Shading to apply stepped shading across an object, creating a gradient effect with distinct color bands. Outlines around the object, achieved here using a custom shader that… Continue reading Simplified Cel Shader in Three.js

Custom Blending Equation Constants
Custom Blending Equation Constants These work with all material types. First set the material’s blending mode to THREE.CustomBlending, then set the desired Blending Equation, Source Factor and Destination Factor. Code Example const material = new THREE.MeshBasicMaterial( {color: 0x00ff00} ); material.blending = THREE.CustomBlending; material.blendEquation = THREE.AddEquation; //default material.blendSrc = THREE.SrcAlphaFactor; //default material.blendDst = THREE.OneMinusSrcAlphaFactor; //default Examples… Continue reading Custom Blending Equation Constants
Positional Audio
Positional Audio Create a positional audio object. This uses the Web Audio API. Code Example // create an AudioListener and add it to the camera const listener = new THREE.AudioListener(); camera.add( listener ); // create the PositionalAudio object (passing in the listener) const sound = new THREE.PositionalAudio( listener ); // load a sound and set it… Continue reading Positional Audio
Keyframe Track
KeyframeTrack A KeyframeTrack is a timed sequence of keyframes, which are composed of lists of times and related values, and which are used to animate a specific property of an object. For an overview of the different elements of the three.js animation system see the “Animation System” article in the “Next Steps” section of the manual.… Continue reading Keyframe Track
Animation Object Group
Animation Object Group A group of objects that receives a shared animation state. For an overview of the different elements of the three.js animation system see the “Animation System” article in the “Next Steps” section of the manual. Usage: Add objects you would otherwise pass as ‘root’ to the constructor or the clipAction method of AnimationMixer and instead pass… Continue reading Animation Object Group
Tone Mapping
Overview: Tone mapping is a technique used to convert high dynamic range (HDR) images to a lower dynamic range suitable for display. In Three.js, tone mapping enhances the realism of scenes by accurately representing light and shadow. Use Case: Tone mapping is essential for applications requiring realistic lighting, such as architectural visualizations or photorealistic renderings.… Continue reading Tone Mapping
Shaders
Overview: Shaders are small programs that run on the GPU and dictate how vertices and pixels are processed in Three.js. They enable developers to create custom visual effects, from simple color changes to complex materials and lighting effects. Use Case: Shaders are perfect for scenarios requiring unique visual styles or effects that go beyond the… Continue reading Shaders
