Greetings,
I'm trying to render partially transparent polygons on the GE API,
and getting strange results. It's a bit hard to explain, so please
check this link for a live version of the API and a .swf movie of what
it looks like on my computer:
http://gaialab.asu.edu/DAAHL/checkboxes.htm
The live version has two checkboxes that toggle different .kml polygon
layers from my server, and the movie version was made from my
computer, showing what happens to the two polygons when I pan and
zoom.
As you can see I'm only getting part of the polygons to render, and
the part that's visible changes depending on how I pan and zoom. The
live version will probably look normal to users who don't have this
problem, but it happens here on a number of computers. This seems to
be the same kind of behavior I get in DirectX mode in regular Google
Earth, where OpenGL fails to render transparent polygons at all--for
example, rendering them as solid black to solid red depending on where
the transparency slider is set.
Any help would be appreciated--it's difficult to develop anything for
the new GE API when I can't see what's really happening.
Thanks,
-Steve
