[osflash] Q: Papervision 3D vs Sandy, vs Away3d

[John Grden]

PV3D 1.5 was about a 40%+ increase in speed.  Away3D was based on PV3D's
original engine, but I've heard they're doing a restructure of the engine,
so I don't know if they'll adopt some of the techniques 1.5 has or if
they'll go a different direction.

I don't know about Sandy to be honest.

Ricardo did some tests with PV3D and Away3D, but this was *before* the
1.5release - I would have to assume he would see a significant
increase in
speed with 1.5:

then, he did what we now call a "doobie" test with Ralph (triangles rendered
per second is a doobie count - the higher the #, the better obviously):
http://mrdoob.com/?postid=394

Learning curve:
PV3D has a really good wiki  (wiki.papervision3d.org), tons of tutorials,
sample files and blog entries (blog.papervision3d.org,
www.rockonflash.com/blog/, www.unitzeroone.com)

there's also the new PV3D CS3 Components that lower the entry bar even lower
than ever.  New features like code generation help you get started even if
you're not a coder - and it all works at DESIGN time.

I can't really speak for Sandy or Away3D on the learning curve, but I can
say that all 3 API's are very similar, and the approach is nearly identical
from a usage stand point.

I *can* speak on PV3D's focus:  to provide a very fast, lean consistent
engine.  Features don't come as quickly as we'd like, but the the engine is
very tight and some things we're doing have to come first before we can add
certain features.

Away3D's team have done an impressive job on their features and version of
the PV3D engine - really outstanding stuff going on there.

Anyway, hope that helps some.
