A class containing useful utility functions for scene manipulation. Import SceneUtils is an add-on, and must be imported explicitly. See Installation / Addons. import * as SceneUtils from ‘three/addons/utils/SceneUtils.js’; Methods .createMeshesFromInstancedMesh ( instancedMesh : InstancedMesh ) : Group instancedMesh — The instanced mesh. Creates a new group object that contains a new mesh for each instance of the given instanced… Continue reading SceneUtils

Import SkeletonUtils is an add-on, and must be imported explicitly. See Installation / Addons. import * as SkeletonUtils from ‘three/addons/utils/SkeletonUtils.js’; Methods .clone ( object : Object3D ) : Object3D Clones the given object and its descendants, ensuring that any SkinnedMesh instances are correctly associated with their bones. Bones are also cloned, and must be descendants of the object passed to this method.… Continue reading SkeletonUtils

XREstimatedLight uses WebXR’s light estimation to create a light probe, a directional light, and (optionally) an environment map that model the user’s real-world environment and lighting. As WebXR updates the light and environment estimation, XREstimatedLight automatically updates the light probe, directional light, and environment map. It’s important to specify light-estimation as an optional or required feature when… Continue reading XREstimatedLight

Constructor for the GLSL program sent to vertex and fragment shaders, including default uniforms and attributes. Built-in uniforms and attributes Vertex shader (unconditional): // = object.matrixWorld uniform mat4 modelMatrix; // = camera.matrixWorldInverse * object.matrixWorld uniform mat4 modelViewMatrix; // = camera.projectionMatrix uniform mat4 projectionMatrix; // = camera.matrixWorldInverse uniform mat4 viewMatrix; // = inverse transpose of modelViewMatrix… Continue reading WebGLProgram

When creating visually compelling 3D objects, adding textures can significantly enhance realism. One such texture that adds detail and depth to materials is FlakesTexture, which can simulate the appearance of surfaces like metallic paint or car coatings. This texture is part of the THREE.js library and works in conjunction with MeshPhysicalMaterial to create surfaces with… Continue reading Using FlakesTexture for enhanced realism in ThreeJS

In 3D graphics, adding dynamic environmental elements like clouds can enhance the realism and immersion of the scene. In this article, we will explore how to create a cloud system using Three.js. The cloud system will be based on particle systems, allowing for smooth movement and animation of clouds across the sky. Step 1: Setting… Continue reading Dynamic Procedural Clouds in ThreeJS

When building immersive 3D experiences using Three.js, it is often necessary to switch between different scenes, such as moving from one environment to another or loading different levels in a game. However, abrupt scene changes can be jarring for users, breaking the immersion and flow of the experience. To avoid this, developers can use smooth… Continue reading Techniques for Seamless Transitions
