WebGLShaderPrecisionFormat: precision property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
The read-only WebGLShaderPrecisionFormat.precision property returns the number of bits of precision that can be represented.
For integer formats this value is always 0.
Examples
js
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT).precision; // 23
gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_INT).precision; // 0
