GLMorphic

Hi

I've been playing with GLMorphic, updating it to work with current
CroquetGL. I've been using it as my Display canvas for a couple of
days, and I like the idea of allowing Morphs to use OpenGL in their
drawOn: methods (makes for much faster transform morphs ;)

There's plenty of problems, and performance isn't great, but do people
think better OpenGL integration is something that's still worth
pursuing? (not necessarily based on GLMorphic)

If you want to give it a try, I've updated the
ConfigurationOfGLMorphic in the squeaksource.com/GLMorphic repository.
Load the #lastVersion (development) and try and enable the GLCanvas with

        GLDisplayScreen new

Works okay here on my i5 with Mesa (software) rendering, and pretty
well when run on an nVidia card. I've only tried it on Linux, but it
should work wherever CroquetGL works.

There's a little example morph in the GLMorphic-Examples category that
renders a rotating cube in its drawSubmorphsOn:

Best,
- -Tim

PS: Please do not judge me too harsh for the GL code - never really
played with OpenGL before.

Yes! My dream GUI would be a Smalltalk widget library that draws into
Areithfa Ffenestri windows via OpenGL (or maybe Cairo). Native windows
would play nicely with the OS window manager, and Smalltalk widgets
would give us a consistent experience across platforms. Visualworks is
going in that direction with Cairo, and Igor's nascent Athens project
looks interesting, but we haven't really seen such a beast yet.

for Morphic (and for rest of stuff of course).
At some point, i will certainly start implementing OpenGL backend for Athens
and will certainly use some of the work from GLMorphic.

Btw, I just added back texture support to CroquetGL, see attachment (will add to repo when I get access).
