Through a rigorous review process we have selected 38 full papers from a total of 93 submissions and 32 short papers. We were very happy with the high quality of papers and the large number of submissions. It is clear from this that GRAPHITE is has emerged as one of the premiere computer graphics conferences.It was a very difficult decision to accept so few papers from such a strong set of submissions. Luckily however we did not have to make the decision ourselves. We would like to thank the 39 members of the program committee who provided excellent feedback on the paper submissions, to very tight timescales. We know that a conference such this is impossible to organize without the support of the research community and we are very grateful for the time they have spent on paper reviews and the efforts of the papers' authors.As a result of these efforts we have been able to put together an excellent program that has technical content from a wide variety of computer graphics topics, ranging from non-photorealistic rendering techniques to virtual reality input devices and cloth simulation. It is good to see such a breadth of topics being presented in one conference and there should be something new for every attendee to learn more about the field of Computer Graphics and Interactive techniques.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115090090","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}

All of our techniques are based on psychology research; the ways this has been used are explained in detail. Our system runs in real-time, allowing quick experimentation with different ideas. The attention shifts for each actor, along with the associated gaze shifts, are controlled by a set of communicating agents. The agents can make requests for shifts of gaze and a gaze control agent sorts these according to priority. In our system each actor builds its own mental model of the world, based on its monitoring of other actors in the crowd. We argue that because we are using only the limited information from this mental model to decide the actor's behaviour, our simulation produces more realistic behaviour than previous work.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126597134","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 system exactly preserves the user's strokes, which may be entered in any order, and depicts them with a chalk texture to evoke a blackboard metaphor. The system automatically interprets the geometry of the sketch, distinguishing vertices, edges, and arrow heads, then tacitly imparts the intended graph semantics based on the two-dimensional placement of these elements. Once drawn, the user can manipulate the directed graph gesturally using the pen. The system responds to vertices or edges being picked and dragged by adjusting all adjacent edges appropriately. The original appearance of the hand-drawn vertices and edges is maintained even while their shapes are continually morphed in response to rearrangement of these elements. All edges exhibit shape memory, which is the proclivity to return to their original hand-drawn shape despite repeated stretching and compression.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131526522","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}

Artists expressing 3D scenes, however, create nonlinear projections that balance their linear perspective view of a scene with elements of aesthetic style, layout and relative importance of scene objects. Manipulating the many parameters of a linear perspective camera to achieve a desired view is not easy. Controlling and combining multiple such cameras to specify a nonlinear projection is an even more cumbersome task. This paper presents a direct interface, where an artist manipulates in 2D the desired projection of a few features of the 3D scene. The features represent a rich set of constraints which define the overall projection of the 3D scene. Desirable properties of local linear perspective and global scene coherence drive a heuristic algorithm that attempts to interactively satisfy the given constraints as a weight-averaged projection of a minimal set of linear perspective cameras. This paper shows that 2D feature constraints are a direct and effective approach to control both the 2D layout of scene objects and the conceptually complex, high dimensional parameter space of nonlinear scene projection.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131757678","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 Spider Cursor is simple to learn and use, and is useful to help extract various types of relationships present in the data. Additionally, it implements a dual presentation mode, in which visual and aural attributes are used to represent information. A cursor in the shape of a spider runs on top of a surface, helping location of information at neighboring points of the geometry. That can be used for data analysis as well as model manipulations (such as cuts and marks). Sound is employed to display complementary and supplementary information as well as to help define orientation.

However, most available methods can not work well for soft and deformable object like cloth. The quality of works mostly depends on the efficiency of hardware as same as the cloth and garment pattern modeling methods. In this research, real time cloth modeling for costume design and making is proposed using mass-spring model and cellular structure space model. For representing realistic cloth, mass-spring model is parameterized under Newton laws, while cellular structured space model is defined for keeping the structure of each garment pattern. Then, the pattern is scaled to fit the input user's body size and clothed on user's virtual body. Furthermore, this pattern can be printed out as a set of ready-to-cut patterns. Proposed 3D modeling for costume design can reduce material cost and computational time for pattern making, and also enable dress remaking and refitting process in real time.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114328336","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 approximation of contours in sketching involves multiple overlapping strokes that are relatively long in regions of low curvature and shorter in high-curvature areas, yet unimportant high-curvature details are omitted in the initial stages of a sketch. Rendering contours with a single long stroke does not capture the feel of a sketch, and a simple strategy of breaking strokes at curvature maxima is easily confused by unimportant details and noise. We address the contour breaking problem for sketching by clustering samples of the contour based on proximity and orientation, making use of a global clustering algorithm (normalized cuts). The strokes generated by this approach qualitatively resemble those produced by real artists, and the successive approximation effect seen in sketching can be simulated by employing our approach at a succession of scales (increasing the number of clusters).","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122864923","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}

A curve on a mesh is frequently used as a boundary curve of a specific region of a mesh in mesh modeling and applications such as texture mapping, remeshing or morphing. Although the curve defined in this paper is a piecewise linear approximation of a strict parametric curve, it is guaranteed that such a curve is just on a mesh. The basic idea is creating a curve on a spherical parameterization instead of direct definition on a mesh. The computation of this curve is done by using only the control points on a spherical parameterization which does not depend on the number of vertices in a mesh. This enables interactive creation/modification of curves even for dense meshes.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115839717","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}
