projection-matrix

Hi Guys,

In my iphone app, i need to project 3d scene into the 2D coordinates of the screen for some calculations. My objects go through various rotations, translations and scaling. So i figured i need to multiply the vertices with ModelView matrix first, then i need to multiply it with the Orthogonal projection matrix.

First of all am on the right track?

I have the Model View Matrix, but need the projection matrix. Is there a glorthof equivalent in ES 2.0?

PS: i am new to opengl.

Thanks for your help.
