When bump map data is derived from geometric descriptions of surface detail (such as height maps), only the lighting effects caused by the surface orientation are preserved. The significant lighting cues due to lighting occlusion by surface details are lost. While it is common to use another texture channel to hold an \"ambient occlusion\" field, this only provides a darkening effect which is independent of the direction from which the surface is being lit and requires an auxiliary channel of data. In this chapter, we present a modification to the Radiosity Normal Mapping system that we have described in this course in the past. This modification provides a directional occlusion function to the bump maps, which requires no additional texture memory and is faster than our previous non-shadowing solution.","PeriodicalId":184610,"journal":{"name":"ACM SIGGRAPH 2007 courses","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128687310","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 as humans have a built in sensory system to know what looks right to our eyes and stomach, and finding that acceptable (and tasty) look was the main focus. To achieve this we used subtle illumination techniques that became a general approach we could use for a variety of objects. In this course we will go over a brief technical overview, then descriptions of different concepts, techniques and systems to achieving the look.","PeriodicalId":184610,"journal":{"name":"ACM SIGGRAPH 2007 courses","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129717059","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}

After a user sketches a two dimensional sketch consisting of connected straight and curved strokes, the sketch is processed by two optimization-based reconstruction algorithms that can reconstruct sketches of 3D objects made up of straight lines and planar curves. The proposed implementation allows certain types of objects with over 50 strokes to be reconstructed in interactive time. Following reconstruction, the structural properties of the 3D shape can be examined using finite element analysis. The object can quickly be modified using the pen-based interface according to the results of the analysis. The combination of a rapid, sketch-based design interface and finite element analysis allows users to iteratively design, analyze and modify 3D objects in an intuitive and flexible way.","PeriodicalId":184610,"journal":{"name":"ACM SIGGRAPH 2007 courses","volume":"10878 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115285796","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}
