Attain Smooth Rendering on the Web for Big Projects

Creating large-scale web-based 3D projects that render smoothly can be challenging due to the limitations of browser environments and the diversity of user hardware. Achieving optimal performance involves a combination of optimizing 3D assets, employing efficient coding practices, and leveraging the capabilities of modern web technologies. This article provides strategies to minimize and attain smooth… Continue reading Attain Smooth Rendering on the Web for Big Projects

Shaders in Blender and Three.js

Shaders are essential for defining how 3D objects are rendered. They determine how surfaces interact with light, creating a range of visual effects from basic colors to complex, photorealistic materials. Blender and Three.js both offer powerful shader capabilities, but they are designed for different contexts and have unique features. This article compares shaders in Blender… Continue reading Shaders in Blender and Three.js

Export and Load 3D Character Animations on Three.js from Blender

Creating 3D character animations in Blender and bringing them to life on the web using Three.js is an exciting process. This article will guide you through exporting 3D character animations from Blender and loading them into a Three.js project. Create and Animate Your Character in Blender 1. **Model Your Character**: – Use Blender to create… Continue reading Export and Load 3D Character Animations on Three.js from Blender

TextureLoader in ThreeJs

Class for loading a texture. This uses the ImageLoader internally for loading files. Code Example const texture = new THREE.TextureLoader().load(‘textures/land_ocean_ice_cloud_2048.jpg’ ); // immediately use the texture for material creation const material = new THREE.MeshBasicMaterial( { map:texture } ); Code Example with Callbacks // instantiate a loader const loader = new THREE.TextureLoader(); // load a resource loader.load( // resource… Continue reading TextureLoader in ThreeJs

CameraHelper in ThreeJs

This helps with visualizing what a camera contains in its frustum. It visualizes the frustum of a camera using a LineSegments. CameraHelper must be a child of the scene. Code Example const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); const helper = new THREE.CameraHelper( camera ); scene.add( helper ); Constructor CameraHelper( camera… Continue reading CameraHelper in ThreeJs

Raycaster in ThreeJs

This class is designed to assist with raycasting. Raycasting is used for mouse picking (working out what objects in the 3d space the mouse is over) amongst other things. Code Example const raycaster = new THREE.Raycaster(); const pointer = new THREE.Vector2(); function onPointerMove( event ) { // calculate pointer position in normalized device coordinates // (-1… Continue reading Raycaster in ThreeJs

PerspectiveCamera in Three.js

Camera that uses perspective projection. This projection mode is designed to mimic the way the human eye sees. It is the most common projection mode used for rendering a 3D scene. Code Example const camera = new THREE.PerspectiveCamera( 45, width / height, 1, 1000 ); scene.add( camera ); Constructor PerspectiveCamera( fov : Number, aspect : Number, near : Number,… Continue reading PerspectiveCamera in Three.js
