  • Production Global Illumination
    CIS 497 Senior Capstone Design Project Project Proposal Specification Instructors: Norman I. Badler and Aline Normoyle Production Global Illumination Yining Karl Li Advisor: Norman Badler and Aline Normoyle University of Pennsylvania ABSTRACT For my project, I propose building a production quality global illumination renderer supporting a variety of com- plex features. Such features may include some or all of the following: texturing, subsurface scattering, displacement mapping, deformational motion blur, memory instancing, diffraction, atmospheric scattering, sun&sky, and more. In order to build this renderer, I propose beginning with my existing massively parallel CUDA-based pathtracing core and then exploring methods to accelerate pathtracing, such as GPU-based stackless KD-tree construction, and multiple importance sampling. I also propose investigating and possible implementing alternate GI algorithms that can build on top of pathtracing, such as progressive photon mapping and multiresolution radiosity caching. The final goal of this project is to finish with a renderer capable of rendering out highly complex scenes and anima- tions from programs such as Maya, with high quality global illumination, in a timespan measuring in minutes ra- ther than hours.

  • Introducing Arnold Single-User Questions and Answers
    Introducing Arnold Single-User Questions and Answers Overview There’s a new way to buy Arnold. Monthly, annual, and 3-year single-user subscriptions of Arnold are now available on the Autodesk e-store, simplifying the process of subscribing to, accessing, installing, and renewing Arnold. Moving the Arnold buying experience to the Autodesk e-store means you now get immediate access to your software when you subscribe, and you no longer have to install and configure multi-user license servers when you only need a single seat. Annual and 3-year single-user licenses are now also available from authorized Autodesk resellers, in addition to annual and 3-year multi-user licenses. Questions and Answers 1. What are my subscription options? There are several ways to subscribe to Arnold. If you are an individual artist or small studio rendering on a local network of workstations, your best option is to get a monthly, annual, or 3-year single-user subscription on the Autodesk e-store. Arnold will no longer be available for purchase from the Arnold website (arnoldrenderer.com). Upon subscribing to Arnold on the e-store, you will be prompted to create an Autodesk Account where you can access your subscription. If you are using Arnold on a render farm and require multi-user licenses, you can purchase annual and 3-year multi-user subscriptions from an authorized reseller. Arnold is also available for pay-per-use on the following cloud rendering platforms: AWS Thinkbox Marketplace, Microsoft Azure, Zync Render on Google Cloud Platform, and Conductor Technologies. 2. What do you mean by “single-user”? With a single-user subscription, it’s now possible to simply sign into your Autodesk account to access and start using Arnold.
