To offset all drawing at a certain point, you can use glTranslatef(x, y, z), this changes the model/view matrix so that all subsequent drawing is offset by the amount you specify. To crop the output you can use glScissor. So before drawing your inner window you could do something like:
glScissor(offset_x, offset_y, 800, 600) glEnable(GL_SCISSOR_TEST) glTranslatef(offset_x, offset_y, 0) then when you are finished drawing the inner window: glLoadIdentity() glDisable(GL_SCISSOR_TEST) to be able to draw on the whole pyglet window again. hth, -Casey On Thu, Feb 11, 2010 at 2:39 AM, Philippe <[email protected]> wrote: > Hello, > > I am new to pyglet. > Here is my little issue. > > I draw sprites, animate them, ... it's great. > Now, I would like to show only a part of what I display. > > I can simply change the size of the window.
