Hi all,

Patrick,

significantly faster

Hum what kind of optimization are you thinking about?
You can fastly have a textured 3D object. THe problem with the
panomaker is that we have to  slice the bitmap into several triangles
to make the distortion correct because of the large bitmap.

Patrick I think your idea of displasment filters is interessting, but
i'm pretty sure it will not be faster. But if someone want to try it,
please do :)

The main problem with Flash hack texturing is it is using a skew of a
small part or the bitmap. Others 'real' 3D engines are using a drawing
system very different from the one we use in Flash. A pixel based
operation (like bi-linar interpolation and more) are needed to have a
perfect texture. But Flash (at least with player 8) can't do this (it
will be much slower!).
Andre Michelle has implemented a real 3D engine with Z-buffer in
player 8.5. In this case the texture is quite perfect. So until AS3
I'll not be able to improve this.

The Panomaker is a great thing, but it's not what Sandy is designed for.
3D in Flash will always be limitated, and Panomaker requires a
specific engine designed for this application. Sandy wants to be
generic, as complete as possible.

But i'm sure AS3 brings a lot of new possibilities, and I'm waiting
the BETA of player 8.5 to begin the migration ;)
