In Wings3D (http://www.wings3d.com/), I have the following issues
- Vertices are not displayed at all (whatever the vertex size I
set in preferences)
- Edges are not highlighted properly when selected.
My setup is the following:
- ATI Radeon 9000 64MB
- Fedora Core 4 kernel 2.6.14
- Xorg 6.8.x
- Wings3D 0.98.32b
The same version of Wings3D works without problem with the same
software setup on a PC equipped with an Intel graphic chipset.
People from Wings3D think the problem comes from the Linux OpenGL
Another Wings3D user reported the same problem with a Radeon 9200
and said the problem disappeared after he installed ATI's
proprietary drivers. (See URL for the whole forum thread)
Forgot the URL for the thread on Wings3D forums:
This looks like another case of an application requiring large point sizes
(making this NOTABUG), however edge highlighting may be a different problem. See
also https://bugs.freedesktop.org/show_bug.cgi?id=702. blender fixed this some
Nevertheless, since you're using a r200-derived chip and not a r100-based one,
try using mesa cvs / dri driver snapshot, the driver there supports large point
sizes (the code in question was added recently and will not make it into xorg
6.9/7.0). Not sure if it would work, as far as I can tell wings3d uses a hint to
set smooth points or not, I believe this gets ignored so hopefully it would work
(the driver does not support large smooth point sizes).
It works with the proprietary driver because this driver emulates large (smooth)
point sizes by some means. This is completely optional driver behaviour and in
no way necessary by the OGL spec.
The vertex issue is definitely a duplicate of
But I'm not sure I'll have the courage to try CVS snapshot.
I'll wait a few months.
Thanks for the explanation.

you can grab nightly binary snapshots of cvs here:
Did Alex's suggestion help?
I tried the CVS snapshots back in November, but it broke my X installation.
IIRC, I wasn't able to start X after I installed the packages.
I think it was a depency problem with my Fedora Core 4 installation, so I gave up.
I have re-installed FC5 a few months ago, I should give Wings3D another try to
see if it is fixed with the latest xorg packages.
I tested it yesterday on the same computer with Fedora Core 5 and Xorg 7.0.
Unfortunately, I saw the same symptoms as before: large vertices size still
doesn't work in Wings with my Radeon 9000.

In fact, I'm not sure which version of xorg it is.
It seems the numbering has changed in FC5, and is a bit confusing.
