  GEM's rendering engine: a mystery unrevealed
 
    Gem was the first extension to Miller Puckette's *em pure-data*
that allowed graphics-processing within this environment.

    Because Gem's hierarchical approach differs significantly 
from pd's "native" linear signal-flow model,
the underlying rendering engine has proven to be a bit complicated.
What's more, this engine keeps changing, which makes it even harder to understand.

    This article aims to shed some light on what is the core part 
of more than a 100.000 lines of source-code.
