The WebGLShaderPrecisionFormat interface is part of the WebGL API and represents the information returned by calling the WebGLRenderingContext.getShaderPrecisionFormat()
method.
Properties
WebGLShaderPrecisionFormat.rangeMin
Read only- The base 2 log of the absolute value of the minimum value that can be represented.
WebGLShaderPrecisionFormat.rangeMax
Read only- The base 2 log of the absolute value of the maximum value that can be represented.
WebGLShaderPrecisionFormat.precision
Read only- The number of bits of precision that can be represented. For integer formats this value is always 0.
Examples
A WebGLShaderPrecisionFormat
object is returned by the WebGLRenderingContext.getShaderPrecisionFormat()
method.
var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT);
// WebGLShaderPrecisionFormat { rangeMin: 127, rangeMax: 127, precision: 23 }
