Frustum Culling
Overview: Frustum culling is an optimization technique used in Three.js to enhance rendering performance by eliminating objects outside the camera’s view. By determining which objects are within the camera’s frustum (the visible area), it avoids unnecessary processing for objects that won’t be seen. Use Case: Frustum culling is essential for applications with complex scenes, such… Continue reading Frustum Culling
Troika Text
Troika Text (troika-three-text) is a modern text-rendering library for Three.js that takes the best features of BMFonts and makes them more accessible. It supports rendering text directly from .TTF or .WOFF font files, eliminating the need for pre-generating glyphs or bitmap textures. It uses signed distance fields (SDF) for high-quality anti-aliased text that scales smoothly… Continue reading Troika Text
Bitmap Fonts (BMFonts)
Bitmap Fonts (BMFonts) allow you to render text as a series of glyphs (pre-rendered characters) packed into a single BufferGeometry. This method is highly optimized for performance because it batches all the glyphs into one draw call, significantly reducing the rendering load. You can also use Signed Distance Fields (SDF) to create sharp edges on… Continue reading Bitmap Fonts (BMFonts)
Text Geometry (THREE.TextGeometry)
TextGeometry is a native Three.js class that lets you create 3D text using a font file and display it in a scene. The text is fully rendered as a 3D object, meaning you can apply transformations (scale, rotation, position) and materials (textures, lighting, etc.) just like any other 3D mesh. The font needs to be… Continue reading Text Geometry (THREE.TextGeometry)
CSS2DRenderer and CSS3DRenderer
CSS2DRenderer and CSS3DRenderer are renderers designed for integrating HTML and DOM elements into a Three.js scene. Unlike the WebGL renderer that draws 3D objects directly, these renderers allow DOM elements (like divs and spans) to be placed and moved within the scene, making it possible to include traditional web elements like text, buttons, or even… Continue reading CSS2DRenderer and CSS3DRenderer
Optimizing Performance in Three.js with Instanced Meshes
Overview Instanced meshes in Three.js allow you to render multiple copies of the same geometry with different transformations (position, rotation, scale) in a highly efficient manner. This technique significantly reduces the number of draw calls, improving the performance of your 3D applications, especially when dealing with large numbers of identical objects. Key Features: Reduced Draw… Continue reading Optimizing Performance in Three.js with Instanced Meshes
Implementing Physics with Cannon.js in Three.js
Overview Cannon.js is a lightweight, easy-to-use physics engine that integrates seamlessly with Three.js. It allows developers to add realistic physics behaviors, such as collisions, gravity, and rigid body dynamics, to 3D scenes, enhancing the interactivity and realism of applications. Key Features: Realistic Physics Simulation: Simulate gravity, collisions, and rigid body dynamics in real-time. Seamless Integration:… Continue reading Implementing Physics with Cannon.js in Three.js
Building Realistic Terrain with Height Maps in Three.js
Overview Height maps in Three.js are grayscale images that define the elevation of terrain in a scene. By applying a height map to a plane geometry, you can generate realistic landscapes, including mountains, valleys, and other geographical features. Key Features: Realistic Terrain Generation: Use height maps to create detailed, natural-looking environments. Ease of Use: Height… Continue reading Building Realistic Terrain with Height Maps in Three.js
Introduction to Shader Materials: Customizing Visual Effects in Three.js
Overview Shader materials in Three.js allow developers to create custom visual effects by writing GLSL (OpenGL Shading Language) shaders. These shaders provide fine-grained control over how objects are rendered, enabling effects like water reflections, custom lighting, and non-photorealistic rendering. Key Features: Custom Visual Effects: Shaders enable unique visual styles and effects that are difficult to… Continue reading Introduction to Shader Materials: Customizing Visual Effects in Three.js
