[Opde-devel] Alive

[Filip V. <f.v...@gm...>]

Hi everybody,

I'm just dropping a mail to let everybody know I'm alive and am still
working on the project. I had a very little free time lately but it's likely
over now, so I'm back to the renderer service and scene manager to finish
rendering before 0.3. As both the original rendering method and the new one
both sucked performance-wise, I'm now doing a new rewrite that should be
extensible enough to allow different approaches be tested and also
reskinning of the level geometry - something that needs to be done in order
to let Windowshade/TrapTexture scripts to work.

You might have noticed that some levels (mostly T2) refuse to load now and
that the rendering is VERY slow on the rest of them. I'm focusing this. It
seems that the portal traversal is too greedy in our approach (original dark
might have used a screen space polygons [or at least trapesoids(?)], not
bounding rectangles). The rendering is slow because of a massive overdraw
now (and the traversal takes some time as well). One reason is that with
Ogre::StaticGeometry, the renderer sometimes overdraws as much as a half of
the level. Door vision blocking not implemented is one of the reasons as
well. That one will be implemented within the new level geometry code (see
bits 3,4 in the cell flags - 3 being open/closed flag, 4 informs that the
cell is a part of a doorway).

I'm sorry to have let everyone hang in the air (as usual)

That's it.

Filip
