3D turntables using b3d (a stage3d engine)

Hooked up b3d to bdj, a little mp3 wrapper for advanced mp3 playback and this was the result:

 

Added another video (higher res)…

demo features:

(runs at 60 fps on my machine, just down to 25-26 while recording)

bdj

• crossfade
• volume
• pitch adjustment
• addition bend
• and all the usual stuff like: play pause stop seek cue…

b3d

• mouse ray generation
• ray plane intersections (for the mouse dragging)
• as3 native rendering for the interactive areas
• screen space anti aliasing (experimental)
• a fast bloom filter
• a fast DOF filter

If anyone wants more info, or for me to upload a better/longer video or a live playable demo just shout. and I will see what I can do.

 

things to note:

in order to play tracks backwards and pitch them smoothly I had to cache the whole track as a bytearray 1st, although you can extract on the fly it takes about twice as long (not an issue on higher end machines but a problem all the same… oh for a faster as3).

The code for playing an mp3 in reverse came from a response to lees post.
