Another New Version of the Gallery Released

.. I think i need to change the title of this blog to something more like "Release Notices".

In any event,
Tao and i have been working steadily on the Gallery software
and finally decided to let loose with a beta release of what we've got.

You can download it here.

Citris Gallery 2.8.0

I haven't yet taken the time to download this new version. It will take a while even with my broadband connection. It looks like a lot of improvements have been made and that's great!

I have read the few bugs/enhancements to do with VRML on Mantis, and I'm wondering if there are other things in this release that I should look at backporting to the VRML importer.

Hi Dave.

There were a few other small VRML improvements,
some of which were specific i think to our project,
some which are more general.

* Shininess values -
Croquet seems to have absurd values for shininess.
Where a normal openGL app would use something like 100,
Croquet needs more like 100000000000.
This isn't so bad when it's all self-contained,
but when you start importing materials from VRML files,
it makes a huge difference.
So in the VRML import i scaled the incoming
material shininess by 100000000000.
This gives a decent visual agreement between Croquet
and popular modellers. (MilkShape, specifically)

- It's tempting to put this fix right into TMaterial,
but i opted for just the VRML patch.

* Texture vertical invert for meshes -
I scaled the V texture coordinates by -1.
Try loading the attached test file in Croquet.
It loads w/ correct texture coordinates in
my other 3rd party viewers. (Deep Exploration, mainly)


The others i think were fairly app-specific.
One was a fix to a bug i'd introduced.
one was forcing all mesh materials to double-sided.
one was reversing the incoming normals of meshes.
altho i can't honestly recommend doing it,
as some models seem to want it and some not.
