I’m doing a program witch is switching between Ortho(fot text) and Perpective(everything else) mode can I do following ?
set projection;
glPushMartix();
set to ortho mode
set modelview;
draw text;
set projection;
glPopMatrix(); //will it restore the matrix i was using before ?
this is how i have it and it works fine. i intially have ortho then i change it to perspective.
initial projection (ortho)…
glMatrixMode(GL_PROJECTION)
glPushMatrix()
glLoadIdentity()
gluPerspective(msngFieldOfView, msngAspectRatio, mdblNearField, mdblFarField)
glPushMatrix()
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()
glPushMatrix()
…
glPopMatrix()
glPopMatrix()
glPopMatrix()
glFinish() 'finish
'swap the buffers
SwapBuffers(mlngPic1hDC)
