[mmve] Collada vs. X3D

[Shun-Yun H. <shu...@gm...>]

FYI,

Thanks to the pointer given by Prof. Don Brutzman at NPS. Here's a document
by the main architects behind Collada & X3D, on their differences and
complementary:

COLLADA focuses on the toolchain that brings content and assets from diverse
authoring tools
to an application, currently targeting principally the game industry.
COLLADA is an
intermediate format whose primary goal is to represent rich data in multiple
forms, to enable the
transformation of assets as they journey from content tools that use higher
level description
paradigms to applications that require platform-specific optimized
descriptions.

X3D focuses on the visualization of 3D assets within applications. X3D has
principally been
targeted for the Web (thus the name and focus of the Web3D Consortium). X3D
is a delivery
format intended to contain the information needed for interactive
applications. X3D specifies
behaviors and interaction, and it includes both a specific run-time model
that enables picking,
viewing, navigation, and scripting, and an API to manipulate the scene graph
at run-time.
