In LG3D we use the Composite extension only to capture the image of the
window and turn its content to a Texture.
Normal windows are rectangular shape thus their geometry are simple. For
Shaped Window I use Xfixes to retrieve their shape as Regions and convert
this to a geometry and this later is used to build the 3D object for the
All transparent, shadows effect are done in java3d (normaly in hardware), we
do not use Render extension to composite the different images.
Building the final 3D object for a Window (X App) is more difficuilt as I
describe above :-)
The source the code is not integrated to cvs head of lg3d. I think also that
what I describe above will not help you with what you want to do, but if you
have any questions, don't hastitate to cantact me.
