I really wonder, why font renderin is so slow. Is it, that Gem has to generate a whole lot of polygons for this?
actually FTGL uses display-lists for each glyph. (which should be quite fast unless a) it is done in software ;-) and/or b) the glyph-parsing of the text-string is slow...) i don't know right know, how it is done with GLTT.
with which font-renderer is your version of Gem compiled with ? (it should give you a message when the first text-related object is created)
GEM: Graphics Environment for Multimedia GEM: ver: 0.90 GEM: compiled: Sep 7 2004 GEM: maintained by IOhannes m zmoelnig GEM: Authors : Mark Danks (original version on irix/windows) GEM: Chris Clepper (macOS-X) GEM: Daniel Heckenberg (windows) GEM: James Tittle (macOS-X) GEM: IOhannes m zmoelnig (linux/windows) Gem has been compiled with FTGL ! ... GEM: loaded images: /home/freak/big/audio/pd/dev/compo/demo/m/pin .jpg from 0 to 1 skipping 1 GEM: Only using 8 color bits Direct Rendering enabled! GEM: Start rendering
So it is using FTGL, but maybe FTGL on Debian isn't using Direct Rendering? I'll have to check this ...
Ciao
