Introductions

Steve Streeting– OGRE founder & project lead– MD, Torus Knot Software Ltd

My role:– Improving OGRE– Consulting for companies using it– Commercial add-ons (OgreSpeedTree)

Qt is a popular choice with our users!

OGRE / Qt Examples

• Zeany– Works Zebra (Japan)– Marketing production for Japanese automotive

manufacturers– High-quality still and animated renders

• Frapper– Institute of Animation, Filmakademie (Germany)– Tool framework for creating 3D content applications– Facial animation modelling, NPR

Zeany

• WorksZebra needed a high-quality, portable UI• Key requirements:

– Stability– Adaptability & customisation– Internationalisation

Zeany

Demo

Zeany Summary

• Top priorities for Works Zebra are– Empowering the artists– Highest possible quality results

• Qt brings solid & powerful functionality OOTB• Frees WZ team to focus time on core innovation!

Frapper

• Qt: UI editor framework– Flexibility and

extensibility very important

– Needed highly adaptable, user-configurable layouts

– Specialised controls – Cross-platform

Frapper

Panel Type: Network View

Graphical representation of nodes and connections

using QGraphicsView, QGraphicsScene and QGraphicsItem

Fast drawing routines (OpenGL)Can handle large number of

graphic items (nodes, connections)

Easy handling of mouse events

Applications Using Frapper 1/3

Agent FrameworkCreate character centric real-time

applicationsFacial animations using FACS

systemDynamic character control using

several input plugins (webcam, etc.)

Field test at the University Medical Center of Freiburg:

“Recognition of Dynamic Emotional Facial Expression”

Applications Using Frapper 2/3

Non-photorealisticrender applications

Goal: Establish frapper as researchand productionplatform for NPR

Implemetation of several NPR rendering algorithmsas frapper nodes is in progress

Applications Using Frapper 3/3

Data SolverMotion capture retargetingProject mocap data to high-level

animationsystem (e.g. Facial Animation Toolset)

Goal: Establish a user friendlyworkflow in frapper

Frapper Summary

• Filmakademie needed to build a flexible, extendable toolkit for future research

• Qt perfect for extending (e.g Network panel)• Rich UI base that allows future expansion
