<DIV></DIV>>From your final question, I assume you're using Croquet. Since Croquet
<DIV></DIV>
<DIV></DIV>>uses OpenGL, you set up an orthogonal projection just as you would in
<DIV></DIV>
<DIV></DIV>>OpenGL. The projection is set up when a TCamera is initialized; look
<DIV></DIV>
<DIV></DIV>>at the method TCamera>>initFrustum. You can make a subclass of TCamera
<DIV></DIV>
<DIV></DIV>>that overrides this method to set up the projection matrix however you
<DIV></DIV>
<DIV></DIV>>like.

<DIV></DIV>>You send messages to an instanced of GLX (usually named glx) just as

<DIV></DIV>>you would in an OpenGL program written in C.

<DIV></DIV>
<DIV></DIV>>glx glVertex3f: 1 with: 0 with: 0.
