 Agenda●  About COLLADA

● Content for WebGL

●

WebGL Implementations

● Content as a Service

● Consoles to Clouds

● Tools speak COLLADA diale

● Sharing demands spec confo

● Authors are your users

● Be faithful to their content

● Thin clients, Thick clouds

Consoles to Clouds●

The COLLADA project was motived to make (PS3) gamconsole content creation easier and cheaper 

 – XML, XML Schema, URI, ZIP

● Built by the video game industry as a content pipeline l

 – Many authoring tools

 – Hundreds of game engines (players)

● Highly flexible design quickly attracted other industriesCAD, Web, etc.

COLLADA Conformance●

 Anyone may freely use the publicly released COLLADAspecification to implement a product

● Implementers may join the Khronos COLLADA Adopter

Program to test their product. Adopter Benefits:

 –  Access to the COLLADA 1.4 Adopters Package

 – Conformance Test Suite source code and .DAE test

● Strengthens consistency of cross-vendor implementations

●  Assures a reliable content pipeline for everyone

Consoles to Clouds●

The Web has been a storage service● Google 3D Warehouse, 3DVIA, etc. store content

 –  Accessible from the Web

 – Unusable within the Web

 –

Upload and download only● This has to change and is changing

Consoles to Clouds●

The Web has become a major application platform● The web browser is the centerpiece

● Thick to Thin

 – Browser plugins are being replaced by Web Apps

●

Software firewalls and sandboxes – WebGL adds a standard 3D graphics API at last!

 – Mobile devices dominate the landscape

● Performance and power constraints

Consoles to Clouds●

Content processing must move to web servers – Thin client JavaScripts shouldn't be doing it

● Files must give way to databases

 –  Assets are the result of queries

 –

Streaming 3D content● Storage requirements will scale to need cloud servers

Khronos Standards●

COLLADA powers Authoring and Sharing● Native OpenGL and OpenGL ES applications for multip

platforms

● WebGL is OpenGL ES 2.0 for browsers

●

Web browsers are a standard platform on multiple devi● XML (COLLADA, X3D, etc.) and Web Apps work well to

● Warehouses of COLLADA content accelerate WebGL a

COLLADA and WebGL● The Khronos Group is developing COLLADA and WebG

● Most Authoring tools support COLLADA

 – Dialects are appearing, better conformance is need

● Warehouses store content in COLLADA

 –

Just a URL away... eventually● Most Browsers are implementing WebGL (not IE)

 – Users will want 3D content!

WebGL Content● Emerging WebGL frameworks support COLLADA

 – How thick can they really get?

● XML content is relatively easy to access in JavaScript

 – JSON however is JavaScript

 – Import faithfully what the artist created!

● Thick and Thin clients will co-exist for a while

 – WebGL is an API for thin Web Apps

Content Clouds● 3D content warehouses become web native

● Social usage overflows storage

 –  Asset meta data becomes really important

● Specialized content conditioning for different devices

 –

Desktop, laptop, mobile, HDTV, walls, etc.● Cloud servers scale to meet demands

 – Storage, searching, conditioning, streaming

Content Clouds●  Authoring will expand from artistry to capture

 – 3D mass media is on the horizon

 – Everyone will be creating 3D content

 – Quality and complexity will vary greatly

● Processing requirements will increase greatly

 – Client devices will focus on presentation and interac

 – Conditioned content will be streamed
