WebGL Basics
Learn the fundamental concepts of WebGL and how to get started with rendering high-performance graphics.
Getting Started with WebGL
To start with WebGL, you need to create a canvas element and get a WebGL rendering context.
const canvas = document.getElementById('canvas');
const gl = canvas.getContext('webgl');
Basic WebGL Concepts
Understand the basics of graphics rendering, including vertices, indices, and shaders.
- Vertices: Define the points of your 3D object.
- Indices: Specify how the vertices are connected to form triangles.
- Shaders: Small programs that run on the GPU to perform tasks like transforming vertices and coloring pixels.
