    PHYSICALLY BASED RENDERING FOR MAYA [0X1] IRAY FOR MAYA

    CASSIE THIBODEAU - NVIDIA PETER DE LAPPE NVIDIA CHRISTOPH BERNDT 0X1 SOFTWARE

  • Fully Scalable & Interactive

    a simulation of the world as you see and understand it

    Built for Designers

    Intuitive & Easy to Use

  • What is Iray?

    Photorealistic 3D renderer Physically based lights and materials Full floating point Path Tracing Progressive Interactive MDL Material Definition Language Hybrid rendering on GPU and/or CPU Scales with additional CUDA devices

    Start fresh and think like a photographer with a new digital camera !

  • Physically-Based Path Tracing with a strong parallel to photography

    You know what to expect and adjust, we know what to program it all just works

  • Think in terms of the physical world; assign Lighting & Materials; add Iray

    Physically Based Workflow

    Physically Based Materials with BSDF Elements and Functions

    Physically Based Lighting with Emissive Distribution Functions

  • Physically based materials Renderer independent material description (Iray, mental ray, ....) Exchangable between applications (0x1 IFM, 3dsMAX Iray+, ...) Support for measured materials BRDF, BSDF, Layered materials, Thin Film Coatings, Chromatic disperrsion, ...

    Shared Materials MDL - The Material Definition Language

  • Shared Materials MDL - The Material Definition Language

    Diffuse Reflection Diffuse Transmission

    Specular Pure Reflection

    Specular Reflection & Transmission

    Measured BSDF

    Simple Glossy

    Glossy

    Bidirectional Scattering Distribution Functions

  • Anisotropic Absorption & SSS

    Diffuse Spot IES Profile

    Anisotropic w/ Light

    Emissive Distribution Functions

    Volume Distribution Functions

    Anisotropic + IOR & Internal Scattering

    MDL Materials EDF and VDF

  • Layering Materials

    1. Blood 2. Mask

    3. Diffuse-Glossy Paint

    4. Glossy reflection

    5. Glossy reflection

    6. Base component

  • Lighting Emissive Materials Photometric light (Photometric Lights with IES Profiles) Self illumination (Controls are similar to a Photometric Lights)

  • Accurate realism with HDR IBL

  • Caustics Caustics sampler

  • Architectural Sampler

    For many complex light setups converges render solutions faster, employs Metropolis Sampling

  • Light Path Expressions

    L.P.E. what is an LPE? A new method for selectively collecting ray types to named buffers A Regular Expression language or REGEX Write your own custom LPEs Many examples available 0x1 Iray for Maya exposes LPE with handles. . . . Visit blog.irayrender.com for ongoing discussion and examples

  • Light Path Expressions

    LPEs How do they work? LPEs are REGEXs that grep for rays by type and interaction LPEs output to a buffer at render time Buffers can be composited to achieve variations of the original result

    With and without the reflection buffer layer

  • Examples. I want the whole beauty pass:

    BP =

    I want to grep for environment rays only: Env =

    I want to only indirect illumination (two plus bounces) : Indirect =

    I want to only reflections: Reflections =

    more examples here: blog.irayrender.com

    Light Path Expressions

  • Light Path Expressions - Handles

    ( * color ) + = Rays that interact with back wall Rays that do not

  • Which is Iray and which is a Photograph?

  • Iray on VCA On Demand Rendering Power

    Interactive Image Stream

    VCA in Data Center via LAN or WAN

    Persistent Storage for Rapid Updates

    and Minimal Uploads

    Incremental Updates

    Iray Client App

    +10Mbit Down

    Preferred

    Ethernet or Internet

  • Dual GPU workstation = 45 seconds/frame (2x Tesla M2090 GPUs) 30 seconds = 900 frames = 11.25 hours = overnight

    NVIDIA VCA = 9 seconds/frame = 2.25 hours = several per day 16 VCA Cluster = 0.6 seconds/frame = 8.5 minutes = a coffee break

    Renault Production Example
