COLLADA Timeline

COLLADA 1.5 specification combines Game, CAD, GIS

- Mesh and B-rep graphics with effects, kinematics, physics, geo-location

Apple’s Mac OS X Snow Leopard now ships with COLLADA

- Bringing system wide 3D content preview and awareness to applications

Khronos publicly releases COLLADA 1.5 as royalty-free specification

ISO TC184/SC4 approves COLLADA 1.5 as CAD visualization format

Khronos releases COLLADA 1.4 conformance tests to ensure high-quality implementations

We are here!Engaging conformance beta testers to complete COLLADA 1.4 test suite


Khronos Conformance

A standard without strong testing for conformance is not a standard at all

- Strengthens consistency of cross-vendor implementations

- Creates a reliable platform for software developers

Khronos specs have exhaustive set of conformance tests

- Precision and functionality testing

Khronos Administers an Adopters Program for each spec

- Full source access to tests for small fee

- Peer review of uploaded results by working group

Only passing implementations licensed to

use the spec trademark

- Watch for the logo!

- List of conformant implementations can be found at www.khronos.org


COLLADA 1.4 Conformance Any company may freely use the publicly released COLLADA specification

to implement a product

Implementers may join the Khronos COLLADA Adopters Program to test

their product. Adopter Benefits:

Access to the COLLADA 1.4 Adopters Package

Conformance Test Suite source code and .DAE test data

Participation in the COLLADA Adopters Mailing List

A priority channel with the COLLADA working group covering the

specification and conformance tests

Conformant products may use the COLLADA name and logo

Company listing on the Adopting Members and Conformant Products pages


COLLADA Test Suite (CTS) Conformance Badge Logos

Baseline – Basic COLLADA document interchange

Superior – Significant conformance for most COLLADA elements

Exemplary – Robust Understanding and preservation of COLLADA documents

Application Integration

Adopter writes Python scripts to direct their application

CTS runs application through 100s of test cases

Interactive visual results in GUI to aid debugging

Submit passing results to Khronos for verification

OpenGL and WebGL COLLADA powers Authoring and Gaming

Native OpenGL and OpenGL ES applications for multiple platforms

Authoring: Kanzi Solution

Game Engine: Unity Engine

WebGL is OpenGL ES 2.0 for browsers

Web browsers are a standard platform on multiple devices

XML (COLLADA, X3D, etc.) and Web Apps work well together

Warehouses of COLLADA content accelerate WebGL adoption!


Kanzi™ & COLLADA

Prepared by Arto RuotsalainenRightware Oy


Kanzi Idea

3D UI Creation

To Multiple Devices

Faster and Easier!


What is Kanzi?

• Middleware for creating advanced 3D graphical user interfaces for mobile

& embedded devices

• Complete tool-chain to take products from design stages to end devices

• Platform independent solution

• Built on Khronos open standards: OpenGL ES 1.x, OpenGL ES 2.0 and

COLLADA


Kanzi COLLADA Workflow


COLLADA for Rightware

• Allows our customers to choose any COLLADA compliant digital content

creation tool they want (e.g. Softimage, Blender, ...)

• Valuable for middleware products that want to offer the most versatile

tool-chain possible

• Open standard that doesn’t tie you to specific environment or license

XML based format makes in-house solutions easy if required

• Can contribute to COLLADA specification through Khronos

SpiderGL : Overview

JavaScript 3D Graphics library that relies on WebGL for realtime rendering

Helps close the gap between web developers interested in 3D Graphics and experienced CG programmers by offering web-friendly API and tools for 3D web development

Provides typical 3D graphics structures and algorithms to developers

Linear algebra, geometry, visibility culling, fast mesh rendering, multi-resolution, asynchronous content loading, UI, …

Philosophy: ease the development of 3D applications without introducing unnecessary abstraction layers nor preventing low level access

Procedural Core, scene graph can be built on top

Seamless integration into existing code

SpiderGL : ArchitectureGL : WebGL ObjectsUtility constructor functions

Object Wrappers

MeshGL: Renderable 3d Model

MeshJS: Editable 3D Model

Space Math:Math: base math, linear algebra

Space Geometry:geometric objects & algorithms

Space Culling:visibility culling objects & algorithms

Async I/O: asynchronous content loadingHttp requests, priority queues…

Mesh importers

UI: User Interface facilitiesGLUT-like event handling

Interactors (trackball, camera, …)
