hello, unfortunately the support for using Cogl through gobject-introspection is not the best, that's why accessing the CoglMaterial crashes your python interpreter.
However, giving the back actor a depth of -1 and calling Cogl.set_depth_test_enabled(True) should fix your problem. so long :wq buz On Mon, Apr 30, 2012 at 11:17:21AM +0200, Moritz Renftle wrote: > hi, > > i did some further experimenting and went back to approach 1: have two > rectangles with very small depth(z)-distance, rotating both in sync. > to achieve this, i changed the z-rotation center of the front page to > -50 and for the back page to 50. the result is here: > http://imagepaste.nullnetwork.net/viewimage.php?id=3759 > > i'm a bit puzzled, because as you can see in the animation, the red > rectangle gets in front of the green one, but one can still see the > green one through the red one. is this a bug? how can i bring the red > rectangle to the front? > > please help me ;), > moritz > > Am Sonntag, den 29.04.2012, 11:20 +0200 schrieb Moritz Renftle: > > Hello everybody, > > > > I'm trying to create a Rectangle, which has a different front and back > > side, so that if you turn it, you DON'T see the mirrored front-side but > > the back-side.
