Rotate ortho decline in x

OpenGL OpenGL: Basic Coding

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?
