Hi,
I need the following features in Libvob (for Loom):
- - A "between" cs which has two parents, and translates to the point in
the middle *between* these cs.
- - A "translate in polar coordinates" cs, which has one parent and
translates from there, but not in euclidean x/y, but instead in
angle/radius. Needed to make interpolation in wheel view work right.
- - A way to "fade" a number of vobs placed into the scene. On GL, fading
would be implemented by increasing alpha; on AWT, by blending colors
with the background color. For coding to be sane, this needs to work so
that I can tell Libvob, "Ok, from now on ... till now, fade all vobs
this much," like with clipping, so that I can have a method that decides
that we have to fade now, and another method that draws the actual faded
vobs. Additionally, fading needs to be cumulative, i.e. if I say "fade
to 90%," and then again "fade to 90%" before ending the first fade, we
need to fade to 90% * 90%.
I know that's not exactly easy, but we need to start thinking about how
to do this-- fading by hand is *horrible*. (Besides, I cannot seem to
get alpha to work on GL :-( -- at least when setting the alpha in the bg
color of a RectBgVob, it doesn't seem to have any effect.)
