yes and no. Clutter trunk uses PangoCairo to render the glyps to a cache implemented using a GL texture. > Also, from my reading on the web, I gather that OpenGL does not really > handle text so well, and uses either 'Bitmap fonts', 'Outline fonts' > or 'Texture mapped fonts' to display text. this has nothing to do with Clutter. > My question is which of these methods is used internally when the > function "clutter_label_new_with_text" is called? none. > I had a look at the function "clutter_label_new_with_text" in the file > "clutter/clutter-label.c", but here I see that "g_object_new" is being > called.

If so, which one is it? as we say on the website and multiple times in the the documentation, Clutter uses Pango to render the glyphs. > Is there any document(s) that I can refer to better understand text display > (in Clutter/OpenGL). yes: the API reference and the code inside the clutter/pango directory. > p.s. 2: My target embedded device will not have GLUT or GLX. Clutter does not depend on, or require, Glut. ciao, Emmanuele. -- Emmanuele Bassi, OpenedHand Ltd.
