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.
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.

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.
