is a JavaScript API that renders interactive 2D and 3D graphics directly in a web browser— without plugins . It’s based on OpenGL ES, a version of OpenGL designed for embedded systems like mobile devices.
To get started with WebGL, you'll need:
// Define the vertex shader const vertexShaderCode = ` attribute vec3 position; uniform mat4 modelViewMatrix; uniform mat4 projectionMatrix; void main() gl_Position = projectionMatrix * modelViewMatrix * vec4(position, 1.0); is a JavaScript API that renders interactive 2D
// Get the location of the position attribute const positionLocation = gl.getAttribLocation(program, 'position'); uniform mat4 modelViewMatrix
: Written in GLSL ES (OpenGL Shading Language), this code is compiled and executed directly on the GPU. Shaders define how vertices (geometry) and fragments (pixels) are processed to create visual effects. uniform mat4 projectionMatrix
// Create the vertex data const vertices = new Float32Array([ -0.5, -0.5, 0.0, 0.5, -0.5, 0.0, 0.0, 0.5, 0.0 ]);
