Rotate ortho decline in x

[opessoa]

Hi, I have an 2D GIS application thats have a lot of 3d points (lines/polylines/polygons) (ZERO on Z).

My ortho config is this:

        glMatrixMode(GL_PROJECTION);
 
	glLoadIdentity();
 
	glOrtho(m_ptWorldX1, m_ptWorldX2, m_ptWorldY1, m_ptWorldY2, -1, 1);
 
	glTranslated(-m_movedX, m_movedY, 0.0);
 
	// Set the model matrix as the current matrix
	glMatrixMode(GL_MODELVIEW);
 
	glLoadIdentity();

So I need to decline on my Y2 to do a fake 3D vision?

How to do it?
