Introduction
Three.js is the most popular library for 3D graphics in the browser. It abstracts WebGL complexity and lets you create 3D scenes with minimal code.
Basic Concepts
Every Three.js scene needs: scene, camera, and renderer. The scene contains objects, the camera defines perspective, and the renderer paints to the canvas.
Geometries and Materials
Three.js includes predefined geometries: cubes, spheres, planes, and more. Materials define appearance: color, texture, transparency, and reflectivity.
Lighting
Lighting is key to realism. Three.js offers ambient, directional, point, and area lights to create believable atmospheres.
Animations
The animation loop updates the scene every frame. You can rotate objects, move the camera, or deform geometries in real-time.
Optimization
Use BufferGeometry, limit draw calls, and employ LOD (Level of Detail) for distant objects. Performance is crucial in 3D.
Conclusion
Three.js makes 3D accessible on the web. At Vynta, we create interactive 3D experiences that captivate users and differentiate brands.
