Re: FLASH: Interfacing a 3D App with the Flash Synthetizer C Library

[Michael Penne]

Since 3d programs already are designed to handle

shading, lighting, morphing, etc. so well, what I

would really kill for is a batch processor to trace

the bitmaps, along with replacing shaded areas in the

bitmaps with flash gradients. (Streamline will batch,

but resulting files still need much work to be

useful.)
