Does WebGL support Blend Equation Extensions ?

I would like to use the WebGL equivalent of the openGL command, glBlendEquationEXT(GL_MAX_EXT)

Is there any workaround. I would like to have a solution for my problem in the following link. … p-in-webgl


I would also need this functionality in WebGL. Is there any hope that the corresponding OpenCL extension will be implemented soon in WebGL?
