First, sorry for the cross post, but I am desperate on this one!
There is a bug report out for this:
Report Reference ID: imiyqixx
RB3D - Nvidia display problems with alpha transparency
There's no such thing as an "Nvidia Voodoo3" so that report makes
little sense. The description of the visual artifacts is also lacking
detail; a 3DMF model that shows the problem would definitely help. I
have an Nvidia Geforce3 in my current Mac and could easily verify if
this is a genuine problem (though I've never seen anything remotely
like this) but if that user had a 3Dfx Voodoo3 card then there's a
whole mess of new variables that come into play. I had a Voodoo3 in my
previous Mac, and it wasn't quite plug-n-play. In fact, the reason I
got into 3D programming in the first place was to get the Mac port of
GLQuake working properly on my buggy Voodoo card...
Actually, what I am REALLY trying to do is display pictures using
AddShapePictureWithMask. I consistently get white backgrounds.
I have an Object3D with two shapes that represent an indicator light on
and off. Then another Object3D in front of that is a programmable label
name. I draw the label and its mask in two pictures created at run
time. The indicator states and masks are JPEGs created elsewhere.
Has anyone found a workaround for this? What's the hold up getting it
fixed?
If this only happens inside QD3D/RAVE in Classic then there's no hope
in seeing a fix - i.e. Apple ain't gonna fix it. For what it's worth,
I get a lot of rendering errors with QD3D on my GeForce3 card. Some of
the problems seem to be in the RAVE compatibility layer for Nvidia
hardware, so I find it's best to use Carbon Quesa on OS 9 to force a
direct-to-OpenGL path instead of going through RAVE.
No this is OS X. The label Object3D is all white (except for the
letters, obviously) and you can only see the indicator state object if
I turn off the label. On WinXP it's even more interesting. From the top
left corner to the top right corner to the bottom right corner
(triangle) the label is displayed. The opposite half has the indicator
images!
I'm starting to boil over this one...
