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.
lg
Matthias
