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.

Availability: This extension is only available to WebGL1 contexts. In WebGL2, the functionality of this extension is available on the WebGL2 context by default. The constants in WebGL2 are gl.MIN and gl.MAX.

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

var ext = gl.getExtension("EXT_blend_minmax");

gl.blendEquation(ext.MIN_EXT);
gl.blendEquation(ext.MAX_EXT);

gl.blendEquationSeparate(ext.MIN_EXT, ext.MAX_EXT);
