I couldn't find it either, hrmm Anyway it's like this: gl.glMatrixMode(GL10.GL_PROJECTION); gl.glPushMatrix(); gl.glLoadIdentity(); GLU.gluOrtho2D(gl, 0, viewportWidth, viewportHeight, 0); gl.glMatrixMode(GL10.GL_MODELVIEW);
// draw your quad in 2d here - coordinate system is top left = 0,0 to bottom right = width,height gl.glMatrixMode(GL10.GL_PROJECTION); gl.glPopMatrix(); gl.glMatrixMode(GL10.GL_MODELVIEW); On May 10, 5:32 am, Paolo <[email protected]> wrote: > I searched for that, but i did't find anything...
