The render farm is one of the most important, high traffic components of a modern VFX pipeline. Beyond the hardware itself a render farm requires careful management and maintenance to ensure it is operating at peak efficiency. In Wetas case this hardware consists of a mix of over 80,000 CPU cores and a number of GPU resources, and as this has grown it has introduced many interesting scalability challenges. In this talk we aim to present our end-to-end solutions in the render farm space, from the structure of the resource and the inherent problems introduced at this scale, through the development of Plow - our management, queuing and monitoring software, and Kenobi - our job description framework. Finally we will detail the deployment process and production benefits realized. Within each section we intend to present the scalability issues encountered, and detail our strategy, process and results in solving these problems. The ever increasing complexity and computational demands of modern VFX drives Wetas need to innovate in all areas, from surfacing, rendering and simulation but also to core pipeline infrastructure.","PeriodicalId":309834,"journal":{"name":"Proceedings of the 2016 Symposium on Digital Production","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122480618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The story unfolds around you, and as the viewer, you are free to experience the action from a perspective of your choosing. This means you can move around and view the clouds from all angles, while the set and characters interact intimately with the landscape. This type of set is a formidable challenge for traditional animated films where you have huge resources and hours to render each frame, which makes achieving the look and feel of immersive clouds in VR uncharted territory full of difficult challenges. Existing lightweight techniques for real time clouds, such as using geometric shells with translucency shaders, and sprite-based methods, have a combination of poor quality and bad performance in VR, which led us to seek novel methods to tackle the problem. For Allumette, we first modeled clouds in virtual reality by painting cloud shells using a proprietary modeling tool, then used a third party procedural modeling package to create and light the cloud voxel grids. Finally, these grids were exported with a custom file format, and rendered using a ray marcher in our game engine. The resulting clouds take .6ms per eye to render, and immerse the viewer in our cloud city.","PeriodicalId":309834,"journal":{"name":"Proceedings of the 2016 Symposium on Digital Production","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126413286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular I am interested in dealing with problems where there are too many parameters to do a simple exhaustive search, only a small number of parameter combinations are likely to achieve interesting results, but the user still wants to retain creative influence. For a number of years I have been exploring how intricate complex structures may be created by simulating growth processes. In early work, such the Aggregation (Lomas 2005) and Flow series, a small number of parameters controlled various effects that could bias the growth. These could be explored by simply varying all the parameters independently and running simulations to test the results. Simple methods such as these work well when there are up to 3 parameters. However, as the number of parameters increase, the task rapidly becomes increasingly complex, and methods that exhaustively sample all the parameters independently are no longer viable. In this talk I will discuss how I have approached this problem for my recent Cellular Forms (Lomas 2014) and Hybrid Forms (Lomas 2015) works which can have more than 30 parameters, any of which could affect the simulation process in complex and unexpected ways. In particular, systems that have the potential for interesting emergent results often exhibit difficult behavior, where most sets of parameter values create uninteresting regularity or chaos. Only at the transition areas between these states are the most interesting complex results found. To help solve these problems I have been developing a tool called 'Species Explorer'. This uses a hybrid approach that combines both evolutionary and lazy machine learning techniques to assist the user find combinations of parameters that may be worth sampling, helping them to explore for novelty as well as to refine particularly promising results.","PeriodicalId":309834,"journal":{"name":"Proceedings of the 2016 Symposium on Digital Production","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127484090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
