Papervision QuadTree Support

[Andy Zupko]

Hey All -

I've update the SVN (754) with QuadTree support.  Yes, this is  
corrective z-sorting.  You can read up on it here: http://blog.papervision3d.org/2008/10/14/papervision-quadtree-support/ 
, and get a more thorough walkthrough and some demos here: http://blog.zupko.info/?p=177

Report any bugs that might have been created, as there were a fair  
number of revisions to the code base to get things running faster and  
to get this functionality integrated.

enjoy!

-Andy

Great news.

I'm going to find this rather useful on an upcoming project I think.

I was having all sorts of issues with z-fighting when prototyping a tool
to build basic objects out of primitives with low segmentation.

Hope this helps resolve a few issues, and makes the concept more viable.

Clint.

Three cheers for Andy (and a tip of the hat to Away3D)!

this is brilliant timing, i'm about to do a ton of "glitch correction" on a big site, and this may take care of it for me :)

I have an up and running version of Papervision3D BSP rendering. I will integrate and post on this when I'm back from Korea. Oh, and great work Andy and Away!

When do you get back from Korea?! :)

Hi andy, I've tried this render engine out on some pretty complex models, and yeah it does hog CPU, so have to be pretty intelligent with it. But the results are very sharp!

Awesome work, Andy!

Looking forward to getting my hands dirty and hacking it up. ;)

Another implementation of BSP using Papervision3D is used with
http://beta.floorplanner.com/ and exists for over a year.

I bet Ralph's implementation is gonna be even better.

I know makc :-)
I only mentioned floorplanner.com to
a] show BSP is possible
b] shamelessly plug my company :-)

BSP is relatively easy to implement for specific 'types' of scene,
like an architectural plan.
Its much harder to implement for more generic stuff.

Hence the 'long wait'. Be assured though that BSP is coming to PV3D.

Great job as always Andy, I couldn't wait for this any more! :)

However, is it me or the InteractiveScene3D events stopped responding?

Thank-you, this is a wonderful enhancement to the Papervision3D project.

After some brief testing I've found that the CORRECT_Z_FILTER appears to be working correctly, but the QUAD_SPLIT_FILTER and ALL_FILTERS are doing some weird things to my Collada objects that have a CompositeMaterial consisting of GouraudMaterial and a MovieMaterial.

It looks as if the Collada object's polygons are losing their CompositeMaterial where the Quad_Split_Filter is cutting faces in the intersections - so the model looks like it has some sections that are wireframe (where the polygons are being split) and some that are using the Composite Material (non-split polygons).

Any idea why this is happening?

I make it break
http://www.shrewballooba.co.uk/pv/hop/nothingset.jpg
When it first loads I get the above, press R twice and it works.
The material is a gourada material with primitive sphere body and the rest DAE if that's any help.

Tried it in another script with ALLFILTERS got same effect.

tis a bit of a cpu hog (badum tish)
