msgltest is the lua script. the lua library is a loader that loads masgltest.lua as an object. which OS are you on? do you have pdlua installed? marius.

hello cyrille, drawing squares now, I attach the pd-patch (msgltest2-test.pd) and the lua script (msgltest2.lua) that I used. with lua I can draw more than 10000 squares, with gem around 2000. I don't know exactly why lua is faster. maybe because in lua, I create one long gl command list (from glbegin to glend) and in gem I trigger gemhead everytime I draw a square. is there a way to make the gem part faster? marius.

hello,
i have not try the test patch, but the curve object is very ineficient to draw line. can you try to draw as many square as possible in gem, and with luagl?
this 10:1 speed factor is surprising.

hey frank/list, somehow I managed to get luagl working. (I did a fink install lua51 and lua51-dev and the rest (luagl/opengl) was still there from one of my earlier attempts - I am still trying to reconstruct the installation process... running the patch, that you posted some time ago (with the colored lines) I get an amazing speed advantage for lua. is this a valid performance test? because with lua I can draw 20000 lines at a cpu usage of 80%, the gem part eats up 80% already with 2000 lines (10:1). cheers, marius.
