History for Working with scenes
changed:
-
Scenes are an earlier attempt in cmgui to get a heirarchy of graphics
objects. Normally you use a single scene attached to a scene viewer.
You can however create as many new scenes as you want. These are
independent and are either manual (you draw only the things you want in
them) or automatic (empty_g_element, invisible_g_element,
g_element_lines) where any new regions (or groups) added into your
program are added in.
Any scene_viewer can then be pointed to look at your new scene rather than the
default scene.
You can also create a heirarchy of scenes by drawing any scene into any
other scene using gfx draw.
A big flaw in all of this is that if you use regions and create a
heirarchy of finite elements, you have to reproduce this independently
in scenes to get a sensible behaviour. Instead the graphics settings
could attach directly to the scene heirarchy.
