We introduce a biscale Normal Distribution Function (NDF) for microdetails to provide a convenient artistic control over both the global appearance as well as over the appearance of the individual microdetail shapes, while efficiently generating procedural details. Our stable rendering approach simulates a hierarchy of scales and accurately estimates pixel footprint at multiple levels of detail to achieve good temporal stability and antialiasing, making it feasible for real-time rendering applications.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128402561","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}

Like variance shadow maps and convolution shadow maps, moment shadow maps can be filtered directly. Classically, this is used to filter hard shadows but previous works explore other applications. Prefiltered single scattering uses convolution shadow maps to render single scattering in homogenous participating media, variance soft shadow mapping uses variance shadow maps for approximate soft shadows and Fourier opacity mapping uses convolution shadow maps for translucent occluders. We combine these three techniques with moment shadow mapping to arrive at better heuristics with less computational overhead.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126939567","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}

Our method, which relies entirely on the rasterization pipeline, stores fragment information for the entire scene on a multiview and multilayer structure and marches through depth layers to capture both near and distant information for illumination computations. Ray tracing is efficiently achieved by concurrently traversing a novel cube-mapped A-buffer variant in image space that exploits GPU-accelerated double linked lists, decoupled storage, uniform depth subdivision and empty space skipping on a per-fragment basis. We illustrate the effectiveness and quality of our approach on path tracing and ambient occlusion implementations in scenarios, where full scene coverage is of major importance. Finally, we report on the performance and memory usage of our pipeline and compare it against GPGPU ray tracing approaches.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130792354","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}

We use surfels to gather a sampling of the local illumination and propagate the light through the scene using a hierarchy and a set of precomputed light transport paths. The light is then aggregated into caches for lighting of static and dynamic geometry. By using a spherical harmonics representation, caches preserve incident light directions to allow both diffuse and slightly glossy BRDFs for indirect lighting. The sparse sampling of direct light also enables indirect lighting from many light sources and efficient progressive multi-bounce. Furthermore, any existing pipeline can be used for surfel lighting, enabling the use of all kinds of light sources. This also includes area lights which can be computed together with the first bounce indirect illumination of other light sources at no additional cost.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115838552","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}

Deferred shading starts by rendering the entire scene into a series of temporary buffers (a geometry buffer or G-buffer). Then, it performs the shading operations using the contents of these buffers. Hence, deferred shading executes the (potentially expensive) fragment shader exactly once for a given pixel sample, avoiding additional fragment shading invocations due to overdrawing. Although deferred shading requires an extra pass and significant memory overhead to store the G-buffer, it can still be beneficial to performance when fragment shading is sufficiently expensive.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123415997","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 body of research work related to this phenomenon is referred as global illumination and, despite its well known physics laws, remains a challenging problem due to its high computational cost, with even more critical consequences for real-time scenarios. We present here a novel approach to address the real-time global illumination problem using forward rendering techniques. We focus on unshadowed diffuse interaction for the first indirect light bounce in the context of large models such as the complex scenes usually encountered in CAD application scenarios. We propose an approach, inspired from light cuts [Walter et al. 2005], which efficiently generates on-the-fly a fast, multiscale and temporally coherent radiance cache by exploiting the geometry-specific stages of the graphics pipeline, namely the tessellator unit and the geometry shader. Our probabilistic solution is supported by a mathematical analysis and a number of experiments covering a wide range of application scenarios. Moreover, no precomputation is needed and our solution is compatible with dynamic view point, lighting condition, geometry and materials.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128640249","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 this paper, we reformulate the cage-based rigging as an incompressible Stokes problem in the vorticity space. The key to our approach is a compact stencil allowing the expression of fluid-inspired high-order coordinates. Thus, our cage-based coordinates are obtained by vorticity transport as the numerical solution of the linearized Stokes equations. Then, we turn the incompressible creeping Newtonian flow into Stokes equations, and we devise a second-order compact approximation with center differencing for solving the vorticity-stream function. To the best of our knowledge, our work is the first to devise a vorticity-stream function formulation as a computational model for cage-based weighting functions.","PeriodicalId":207863,"journal":{"name":"Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130164299","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}
