hello cyrille,
here i add texture, input for the amount of distance and 3 bangs to change between fill, line and point draw. more clicks more fun in the example ;) also reduced the draw types trifan and tristrip didn´t work on the mesh_square. so i add the shorts, draw P L T S, defined in GemShape.cpp
i´m working on MacBookPro 10.6.2 GeForce 8600M GT

hello the default draw type from circle is POLYGON and this doesn´t work with the default geometry in - and outtypes, geometry_intype GL_TRIANGLES, geometry_outtype GL_TRIANGLE_STRIP.
hum, strange,
this exemple work for me. what is your GPU / OS?
did you mind if i use your version of this exemple to update Gem documentation?
Cyrille
Change circle to mesh_square than it will work. (default draw type is TRIANGLE_STRIP) attached is the modified patch with the possibility to change the draw type. The geometry_types must been set before linking the shaders, to change types the shaders must reload. lg Matthias

hello kind pders,
i have trouble figuring out, why the 10.geometry help-patch does not work for me.
starting rendering constantly prints out "GL: invalid operation" to the console.
apart from the printout, does it work? (sometimes you get an error even though everything appears to work)
i tried finding out, whether it was a limitation of my gpu, but don't think so since i am using a Nvidia 9600M GT on a macbook pro (and once saw a list somewhere, where the opengl version and features where listed).
you can send [print( to the [gemwin] to get such a thing. in theory, Gem shouldn't even call a code that is not supported by your driver.
