the flow and ordering of the rendering of graphics to the Gem world
that you see in the [gemwin].;

it will not be generated. Render chains generally end with an shape
object (sometimes called a "geo").;

#X text 17 63 Gem is based on OpenGL \, which uses the graphics card
to do the processing. That means that instead of directly controlling
the data like you do with Pd messages or audio \, in Gem you are controlling
a "pointer" to the data on the video card.;
#X obj 302 323 gemwin;
#X text 17 137 [gemwin] is a pointer to the output buffer of your video
card. The screen you are looking at is that output buffer drawn to
the screen.;
#X msg 302 255 destroy;
#X text 17 188 So even if there are multiple [gemwin] objects \, there
is only one screen. Each [gemwin] object is then a pointer to the same
window.;
