For this reason, a \"one size fits all\" crowd solution might not be optimal, both in terms of design and usability, but also allocation of crew. In this talk we present a suite of tools, developed across multiple platforms, each optimised for specific crowd tasks. These are underpinned by a data interchange library to allow for modification at any stage of the pipeline.","PeriodicalId":163368,"journal":{"name":"ACM SIGGRAPH 2017 Talks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130343537","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}

Stories are driven by characters and audience investment comes from their empathy for those characters. Unless the viewer is making a concerted effort to look elsewhere on screen, they usually concentrate on the eyes of the main character. Therefore, a great amount of effort and time is spent making the eyes of our characters look as expressive as possible. When done improperly, the eyes will make a character look dead and unappealing. Our technology utilized to create our characters' eyes gives artists the flexibility to push the boundaries of their craft; it helps them portray characters that communicate the emotions that a story requires. In order to achieve this we designed a set of techniques that compose our eye pipeline. It has been refined over many years in a continued effort and collaboration among several departments at our studio, from modeling to lighting passing through animation and rigging. It allows animators to follow their expressive style while also providing materials artists and lighters with the necessary input to achieve a realistic look.","PeriodicalId":163368,"journal":{"name":"ACM SIGGRAPH 2017 Talks","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128272949","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}

Existing contour methods cannot reflect such complexity in an artistically pleasing way (Figure 1 A), and animations are prone to flicker. After a brief explanation of contour generation and its inherent challenges, this talk presents a novel approach to rendering aesthetic and flicker-free contours on highly detailed geometry (Figure 1 B). The new method employs sub-pixel-level sub-sampling to achieve a high level of detail quality, and supports contours in transparency, reflection and refraction. The implementation uses mental ray (Unified Sampling mode) but could be realized in other ray tracing renderers as well.","PeriodicalId":163368,"journal":{"name":"ACM SIGGRAPH 2017 Talks","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121148376","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}

At its core, this technique convolves a circular pattern blur in the frequency domain using a horizontal and a vertical pass, representing the frame buffer using complex numbers. This technique renders at magnitudes faster than brute-force and sprite-based approaches, since it is a separable convolution. Important properties of this technique include convolution separability, low memory bandwidth and large radii circles. The technique has been shipped on Madden NFL 15, Madden NFL 16, Madden NFL 17, Fifa 17 and PGA Tour Rory McIlroy. The implementation includes an offline shader code generation step containing pre-computed frequency domain filters, multiple weighted passes for imaginary and real number processing. We will present the mathematical derivation and some caveats to achieve the required precision for intermediate frequency domain frame buffers.","PeriodicalId":163368,"journal":{"name":"ACM SIGGRAPH 2017 Talks","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121314651","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 ability to execute in an efficient and cost-effective manner requires extensive coordination between different sites, different departments, and different artists. This coordination demands data-intensive analysis of VFX workflows beyond standard project management practices and existing tools. In this paper, we propose a novel solution centered around a general evaluation data model and APIs that convert production data (job/scene/shot/schedule/task) to business intelligence insights enabling performance analytics and generation of data summarization for process controlling. These analytics provide an impact measuring framework for analyzing performance over time, with the introduction of new production technologies, and across separate jobs. Finally, we show how the historical production data can be used to create predictive analytics for the accurate forecasting of future VFX production process performance.","PeriodicalId":163368,"journal":{"name":"ACM SIGGRAPH 2017 Talks","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127651705","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}
