Hi all, Patrick, > I'm still thinking there might be a way to make this all 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 ;) ++ THomas / kiroukou 2006/1/29, Alan Shaw <[EMAIL PROTECTED]>: > > > On 1/28/06, Pablo nopixels <[EMAIL PROTECTED]> wrote: > > > > Yes, Sandy is really cool, but my Pc is running 3 f/sec, your demo is > running really slow with the panorama demo, is it gonna work always like > that? > > > To summarize the discussion of speed in this thread: some optimizations > could be possible on this version, but the real improvement will come when > we have the AS3 version of Sandy. > (We're just talking about the texture mapping here.
