This course will be an introductory presentation targeting Directors, VFX Supervisors, Producers, Studio Executives, Artists of all levels and specialties, elaborating the advantages of using Previs for their productions. The main purpose of Previs is to visualise complex movie sequences before actual production begins. There are many benefits for doing Previs, besides cost saving and aid in the planning process, it helps the producers and directors communicate not only to their crew, but also to studios what they are putting their money into. Previs has also evolved to serve other purposes, such as pitching projects to studios; planning complex scenes through technical previs, etc. The role of the Previz Artists is to work with the Directors in realizing their creative visions, at the same time, it offers an excellent opportunities to collaborate with some of the best creative minds in the industry. Most Previs Artists need to have strong understanding of cinematic languages and craftsmanship as well as solid visual story-telling skills, however the barrier for entry is relatively low as it is not as technical.","PeriodicalId":262594,"journal":{"name":"SIGGRAPH Asia 2012 Courses","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121859941","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}

Damasio and J. LeDoux. Armed with this basic knowledge, we will study the methods used by artists to induce emotions in the history of ancient and contemporary arts. Based on scientific studies, we will highlight the methods to be implemented to induce basic emotions such as fear or joy but also complex as empathy and compassion. We will develop a specific method of emotion induction to the problems of competing game play and video game script. After explaining the concepts of presence in virtual environments, and their sensory and psychological mechanisms we study how emotions play a role in the implementation of presence.","PeriodicalId":262594,"journal":{"name":"SIGGRAPH Asia 2012 Courses","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121464338","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}

However, game developers and many researchers are far more familiar with what's available in DirectX, and still think of OpenGL in terms of version 1 or 2, or OpenGL ES. However, they have the background, often including DirectX 11, to quickly learn what OpenGL has to offer in terms of a new API perspective. This course is designed to exploit this knowledge to quickly move into topics such as new hardware features exposed by OpenGL, and how OpenGL can be used in a high-performance renderer. We will show how difficiencies in older versions of OpenGL have been addressed, such as lack of shader binary support and efficient buffer management, and address topics high performance topics such as multithreading. We will look in some detail at the differences in OpenGL and DirectX that expose opportunities not available in DirectX.","PeriodicalId":262594,"journal":{"name":"SIGGRAPH Asia 2012 Courses","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134319021","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}
{"title":"Projective geometry and duality for graphics, games and visualization","authors":"V. Skala","doi":"10.1145/2407783.2407793","DOIUrl":"https://doi.org/10.1145/2407783.2407793","url":null,"abstract":"The tutorial gives a practical overview of projective geometry and its applications in geometry, GPU computations and games. It will show how typical geometrical and computational problems can be solved easily if reformulated using the projective geometry. Presented algorithms are easy to understand, implement and they are robust. Homogeneous coordinates and projective geometry are mostly connected with geometric transformations only. However the projective extension of the Euclidean system allows reformulation of geometrical problems which can be easily solved. In many cases quite complicated formulae are becoming simple from the geometrical and computational point of view. In addition they lead to simple parallelization and to matrix-vector operations which are convenient for matrix-vector hardware architecture like GPU. In this short tutorial we will introduce \"practical theory\" of the projective space and homogeneous coordinates. We will show that a solution of linear system of equations is equivalent to generalized cross product and how this influences basic geometrical algorithms. The projective formulation is also convenient for computation of barycentric coordinates, as it is actually one cross-product implemented as one clock instruction on GPU. Additional speed up can be expected, too. Moreover use of projective representation enables to postpone division operations in many geometrical problems, which increases robustness and stability of algorithms. There is no need to convert coordinates of points from the homogeneous coordinates to the Euclidean one as the projective formulation supports homogeneous coordinates natively. The presented approach can be applied in computational problems, games and visualization applications as well. The tutorial is targeted to algorithm developers in geometry and graphics, visualization and games. The course is also intended for educators and attendees interested in computational issues in general.","PeriodicalId":262594,"journal":{"name":"SIGGRAPH Asia 2012 Courses","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130505382","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}
