I too see something strange.
The first thing is that the OpenGL demo on my PC (which is XP Home
running under Parallels on my Mac) offers a first window with all
sorts of alternatives to try out. On my Mac (which is OS 10.5.2) I go
straight into the rotating coloured object. Looks as if the versions
are different.
On my PC the demo works as you'd expect. On my Mac, there seems to be
an intermittent problem with a closer face hiding a more distant face.
Thus you sometimes get a look-through effect with objects rotating in
the wrong direction. Very confusing to the eye.
My Mac Java version is also 1.5.0_13.

Brian,
My java version is:
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-

Java HotSpot(TM) Client VM (build 1.5.0_13-119, mixed mode, sharing)
I'm not even sure how I'd update it, as I'm quite new to Mac.
Although it would seem that I'm not too far out of sync.
I guess the font limitation serves me right for not looking at the
source!
I'm not sure how to describe what I see with lookat, so I've
attached a screen grab. This is the image that displays on startup.
Rotating the image (x,y,z keys), results in other strange
variations. It sort of feels like an inverted perspective, which is
being affected by a clipping plane. When I rotate the cube to look
at the back three faces (cyan, magenta, yellow), then it all looks
fine! I've done a source compare with my Windows box, and the source
looks the same. I tried swapping the order of some of the vertices
(from clockwise to counter-clockwise), thinking that maybe it was
being affected by the normals, but that also didn't help.
Regards,
Carl.
Carl,
On my Mac running 10.4.11 the lookat demo seems to
look all right. What java version Are you running?
java -version
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-
b05-241)
Java HotSpot(TM) Client VM (build 1.5.0_13-121, mixed mode, sharing)
The font demos run only on Windows boxes. View the
script for font and you will see the following.
NB. note glaUseFontBitmaps supported in Windows only
