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.;
