The problem is usually solved with best-fit bounding volume hierarchies (BVHs) which require much more memory and time for updating the bounding volumes when the objects deform. Hence, a particle-based collision detection method is enhanced to reduce the checking for non-colliding primitives by adding movable particles on the object vertices corresponding to each particular area. The distance of corresponding particles are computed for selecting the closest vertices between each pair of objects. The experimental results show that the proposed method has less colliding checking time than using BVHs when using with the deformable objects. Moreover, the proposed primitive-checking method can be parallel processed on GPU increasing speed performance while accuracy is still preserved when the results are compared to the previous BVH method.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133478853","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, many classical problems such as order-independent transparency (OIT), occlusion culling have not yet been efficiently solved using the traditional graphics pipeline. The main reason is that the behavior of the current stage of the pipeline is hard to be determined due to the unpredictable future data. Since the rasterization and blending stage are still largely fixed functions on chip, previous improvements on these problems always require hardware modifications thus remain on the theoretical level. In this paper we propose CUDA Renderer, a fully programmable graphics pipeline using compute unified device architecture (CUDA) [NVIDIA 2008] which can completely run on current graphics hardware. Our experimental results have demonstrated significant speedup to traditional graphics pipeline especially on OIT. We believe many other problems can also benefit from this flexible architecture.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117144774","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 introduce a contour-driven approach where the user inputs contours to represent complex shapes, the system estimates automatically the optimal trajectory of the brush, and then renders them into oriental ink painting. Unlike previous work where the brush trajectory is explicitly specified as input, we automatically estimate this trajectory given the outline of the shape to paint. Existing methods can be classified into: (1) methods that explicitly model a virtual 3D brush and mimic its effect on a paper [Wang and Wang 2007], and (2) methods that simulate the rendering effect on a 2D canvas without an explicit 3D brush model [Okabe et al. 2007]. Our approach falls into the second category. Figure 1 shows four results generated by our algorithm.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115759430","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}
