TODAY WE FOCUS ON FOUR DIFFERENT INTEGRATIONS

VISUALISATION INTEGRATION

Visualisation is usually separate from design stage Data may be a different and simplified version of the design data Scalable compute resource desirable Handling legacy data VISUALISATION: REQUIREMENTS

Visualisation is the primary goal of the user Power users understand visualisation algorithms and parameters Good understanding of materials and lighting in multiple 3D systems Will use multiple applications to get the job done Use post processing often Clearly defined workflow aimed at the highest quality results in the shortest time May have visual stylistic preferences Generally tight deadlines and billing by the hour time is of the essence VISUALISATION: USER PROFILE

Expose a high level of control in the UI Fast feedback from settings Fast final render time VISUALISATION: APPLICATION DESIGN

Implications for UI Ability to author complex materials quickly Support for post-process stages Support for 3 rd party plugin software VISUALISATION: APPLICATION DESIGN IMPLICATIONS

MATERIAL STRUCTURE

VISUALISATION: CREATING COMPLEX MATERIALS EASILY

Key Iray+ features Consistent appearance of materials throughout the workflow Interoperability of materials between different Iray applications Physically accurate rendering Support for multiple buffers 32 bit support Scalability for production render Interactive feedback Iray+ for 3ds Max VISUALISATION: KEY IRAY+ FEATURES

CAD INTEGRATION

Connections to Enterprise data systems Lot of internal usage and design review Collaboration between remote teams Analysis and design verification is key Requirement for scalable compute resources Compatibility with other visualisation methods (real-time) Data generally accessible worldwide through central data centres. CAD: REQUIREMENTS

Visualisation is not always the users primary goal Generally not power users who understand visualisation algorithms and parameters Less understanding of digital content (eg materials and lights) and parameters Keep data within their CAD application or network Don t use post processing Clearly defined workflow aimed at designing the best product and getting it to market in the shortest possible time Wants to see accurate representation in different situations CAD: USER PROFILE

Use of predefined settings Only expose key parameters for Materials and Lighting Simple render controls pre-defined to support the particular stages of the design workflow Use of automation/repeatability Automated image generation from PLM systems Hooks into internal animation/explosion Variation control is key CAD: APPLICATION DESIGN

Hooks into internal animation/explosion consistency of content at an enterprise level Ability to author content once then publish them company wide as noneditable Tiered user levels provide the right amount of control for the task Separate tools aimed at specific tasks eg Viewers, Advanced Material editors, Analysis External material editor Lightweight Viewer CAD System CAD: APPLICATION DESIGN

Key Iray+ features Consistency of material representation across different apps using MDL Accuracy of BRDF s provided by measured materials Ease of exposing editable parameters via MDL Key Iray+ features Replacement of OGL viewport using interactive ray-traced modes Iray+ layer simplifies the iray API to create simple controls easily CPU fallback for both engines CAD: KEY IRAY+ FEATURES

Model is marked up with OpenGL materials OpenGL materials are driven from MDL Always get the best looking ray traced viewport Single material description very important for data consistency Enhancement of OpenGL Viewport with RayTraced view Iray Interactive can be used for very fast high quality realtime navigation As well as fast updates to lighting, geometry and material changes. Realtime CAD: OPENGL/RAY TRACED REPRESENTATION

Iray+ material library (300+) gives great starting points for key CAD markets auto/marine etc. Most manufacturers will take these as starting points and create specific palettes of materials for use within whole company and their PLM Ideally these materials can be used from design through to consumer by inserting the appropriate Iray enabled application into the process at each stage i.e. NX->Teamcenter->export to Iray Configurator CAD: PRE-DEFINED CONTENT IS KEY FOR CAD USER

Measured Data can be used just like any other BSDF Measurement is prone to error at grazing angles BRDF measurement provided by Ford Motor Company Data directly from Radiant Zemax Imaging Spheres device CAD: USING MEASURED BSDF DATA

Measured Data can be used just like any other BSDF Measurement prone to error at grazing angles Can add fresnel layers to simulate clearcoat finish and address grazing issues BRDF measurement provided by Ford Motor Company Data directly from Radiant Zemax Imaging Spheres device CAD: USING MEASURED BSDF DATA

Now nearly everyone in the chain wants high quality Manufacturers producing film quality animations for daily automated design review. Automation and repeatable/scriptable processes. Speed of production, scaling important CAD: HIGH QUALITY VISUALS

Analysis higher quality presentation of results For architecture iray provides accurate lighting analysis including caustic effects Daylight Simulation of a London street at hourly intervals CAD: ACCURATE SIMULATION

CONFIGURATORS

In-store or online configuration of consumer products Automated pre-render of segmented images where there are limited variations Data input from or integration with a host design system Live rendering where there are too many variations to pre-render CONFIGURATORS: REQUIREMENTS

Render on cloud or in-store Pre-authored data uploaded to a server Scale across possible large numbers of concurrent users for web based applications Minimise costs Easy/automated update of product lines Appropriate remote compute resource Real-time is often not good enough quality. How real do you need? CONFIGURATORS: REQUIREMENTS

Author Generally will be a design professional working in an industry standard visualisation, CAD or Games system. End user Consumers who have little or no knowledge or interest in the technicalities of the system. They just want to configure their ring/headphones/car as quickly and accurately as possible. CONFIGURATORS: USER PROFILES

Authoring tool Definition of rules for replacement of geometry Define combinations that are not valid for commercial, stylistic or manufacture reasons Support changing product lines Configuration system Browser or simple application based frontend rendering backend OR prerendered images Interactivity and frame-rate importance. Fast response to change CONFIGURATORS: UI IMPLICATIONS

CONFIGURATOR: USED FOR DESIGN REVIEW

CONFIGURATORS: REQUIREMENTS

Representation of MDL materials with realtime (webgl) materials Lightweight Cloud API CPU fallback (cost) Physically based Can mix native CAD with Iray+ content at load time, easier to update Can be image based or interactively generated Images can be cached as they are generated for different configurations Create automated Iray image output direct to site from the CAD OR link Iray directly into the site for rendering CONFIGURATORS: KEY IRAY+ FEATURES AND MDL

CONFIGURATORS: REQUIREMENTS

CONFIGURATORS: REQUIREMENTS Clothing Simulation

Photorealism is now commonplace High quality visualization is required in all aspects from Design to Consumer User requirements are radically different Type of integration is defined by user requirements Iray+ has the breadth of functionality to address a wide range of very different applications MDL provides a way to connect all your workflows with the same look and feel CONCLUSIONS
