Rendering GIMP widgets entirely in OpenGL/FBO?
Hi there,
this is my first contact to GIMP/GTK+ from a developer's point of view.
For a research project I need to be able to render UI widgets/palettes
of a graphics editor (like GIMP) entirely in 3D space. In other words, I
would like to apply 4x4 Matrices (rotation, translation, shearing) onto
the widgets' bounding rectangles and then render these transformed
rectangles directly in 3D space and texture them with the widgets' content.
I have found a very exciting example for Qt (see [1] or [2]) which
exactly demonstrates this. However, unfortunately, I could not find an
open source Qt-based graphics editor that comes close to the features of
GIMP... :-).
Now, my question: Does anybody of you have knowledge about whether and
how I could do something similar in GTK+/GIMP? A small test example
would be great. Of course, I already did a little research and came to
the conclusion that maybe a combination of GIMP, cairo and glitz might
be an excellent starting point. What do you think? Is it possible to
render GIMP/GTK+ widgets entirely in OpenGL, e.g., via FBOs?
My environment of choice would be MS VS 2008/Win32, but I could also
live with mingw or even Linux (I would definitively prefer the first
option, because this is our lab's standard).
Cheers,
Martin.
