OpenGL ES 2.0 Implementing glMultMatrixf -

I am working on porting GLU for OpenGL ES 2.0. Because the version I saw for ES uses 1.1. There are some tasks that are not in 2.0 and I was hoping to get some help with it. OpenGL per ...

glMultMatrix one ???? Multiply the current matrix with the given matrix

OK, so we are passing a matrix and I think we can assume that it is 4x4 (xyzw). But what is the matrix multiplication? Is this gl_position?

Does anyone have an example of porting this function?

In OpenGL ES 1.1, the current matrix is ​​at the top of the existing matrix stack. There are several matrix stacks and you choose one of these:

  glMatrixMode (GL_PROJECTION); Or glamorosomed (GLIMDLUF);   
 The Matrix Stack does not exist in Concept 2.0.  
 Yes, the matrix is ​​always 4 x 4.  
 The source implementation of a well-open GLU is here:
