Task description

we want to implement a 3d game world to flash viewer exporter. The 3D game scene of a user tile world is exported to a group of images and a MCML descriptor file.

• images: contain snapshots of 3D object groups
• MCML descriptor file: contains instances and transformations of the images in a 3D world.

Then, we will use a shared flash file to generate an interactive scene in flash player, by billboarding all images. This will create a paper style scenes, like this one: http://www.youtube.com/watch?v=oiHvMZy1l4k

Goals

The reason is for better marketing ParaWorld. People's content creation in ParaWorld platform can be connected (output) to tranditional web site. This is a marketing feature. So we only need a viewer of 3D world on flash. The ultimate goal is to attract people to download our client and play in the client in full 3D.

Assigned to

LeioZhang and ClaymanS. Please ask ClaymanS for 3d math.

Flash based 3D engine

• papervision3d is an open source 3d engine, I have downloaded its source.
  • see http://wiki.papervision3d.org/index.php?title=Main_Page
• Sandy3D: is an intuitive and user-friendly 3D open-source library developed in Actionscript 2.0 and now Actionscript 3.0 for Adobe Flash.
  • see http://www.flashsandy.org/
• Away3D: is an open source 3d engine
  • see http://www.away3d.org/

Wrapper of 3D engine

• Cast3D does not have it's own rendering engine. So for 3D graphics rendering Cast3D currently is ported to popular 3D engines, Sandy3D and Papervision3D.
  • see http://www.cast3d.org/

additional resources

For flash programming, here is a 3d scene class. we will simply render rectangles.
