EXT_blend_minmax extension
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.
The EXT_blend_minmax extension is part of the WebGL API and extends blending capabilities by adding two new blend equations: the minimum or maximum color components of the source and destination colors.
WebGL extensions are available using the WebGLRenderingContext.getExtension() method. For more information, see also Using Extensions in the WebGL tutorial.
Constants
This extension adds two new constants, which can be used in WebGLRenderingContext.blendEquation() and WebGLRenderingContext.blendEquationSeparate():
ext.MIN_EXT-
Produces the minimum color components of the source and destination colors.
ext.MAX_EXT-
Produces the maximum color components of the source and destination colors.
Examples
const ext = gl.getExtension("EXT_blend_minmax");
gl.blendEquation(ext.MIN_EXT);
gl.blendEquation(ext.MAX_EXT);
gl.blendEquationSeparate(ext.MIN_EXT, ext.MAX_EXT);
