Despite the advances in computer graphics and the whole representation of virtual worlds on 3D environments, 2D-based games still have their space, specially on portable consoles and mobile devices. The visual quality of sprites have increased as a result of hardware improvements in processing power, memory, and a richer color gamut. However, most of the sprite editing task is still manual, using graphics editing tools. We present a method to automatically generate shading distribution on sprites, one important step during the editing process that is time demanding for most manual works on art design today. Our method allows to control the position of a local light source and to generate an approximation of shading distribution effect on sprites. Although our solution is not physically accurate according to the shape of the represented object, it can produce convincing and well usable results for 2D game systems in many practical cases. We compare our fully automatic results with handmade sprite shading, with very convincing results.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"304 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122799904","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 main goal of this work is to provide a procedural generation technique, robust enough in order to create different types of hairs. We propose a parametric model that can produce diversity of obtained results through parameters variation. The model is organized in three steps: firstly, the strands generation, followed by positioning them in the head of the characters. Finally, the third step is responsible for providing cartoon rendering, including common characteristics in cartoon shading, as the black edges and solid colors. Visual inspection of obtained results indicate that generated hairs are coherent with expected in terms of visual aspects.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130652650","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}

Developing games of this nature usually requires a high investment of time and money on Artificial Intelligence techniques, in order to provide better credibility to the characters. For the independent game developers’ community, affording this kind of extra complexity may be highly expensive. Therefore, this article proposes a way of developing character-based games while maintaining high quality and low-cost. This is done by using a modular Artificial Intelligence technique called Rule-Based Systems, integrated with a game development support tool, XNA. Since Java is better provided with Rule-based System tools, the IKVM application is used to allow this integration. All mechanisms and tools used are free. A comparison of free Rule-based Systems is presented, as well as an application of the proposed model on a real game project.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125408257","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 propose the combination of an efficient fluid model, that does not require solution of complicated equations, with a mass-spring approach to simulate the deformable surface. Firstly, we describe the fluid model for simulating the flow and its GPU implementation. The simulation method is based on a particle system, that evolves over a lattice. This lattice is defined over the surface domain. A set of local rules determine the interaction between particles. The elastic surface is simulated by a GPU based mass-spring system, geometrically represented by a regular mesh. The fluid particles are guided by the surface topography interacting with the elastic mesh due to external, elastic and damping forces. In the experimental results we emphasize the fact that physically plausible flow/deformation phenomena can be efficiently reproduced and animated in real time by the combined technique.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116287218","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}

Unfortunately, most of the systems currently available to perform that task are expensive and proprietary. In this work, an open source application for optical motion capture is developed based on digital image analysis techniques. The steps of initialization, tracking, reconstruction and output are all accomplished by the built OpenMoCap software. The defined architecture is designed for real time motion recording and it is flexible, allowing the addition of new optimized modules for specific parts of the capture pipeline, taking advantage of the existing ones. Experiments with two cameras with infrared LEDs and reflexive markers were carried out and the created methodology was assessed. Although not having the same robustness and precision of the compared commercial solution, this work can do simple animations and it serves as an incentive for research in the area.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114893280","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 animation of humanoids in real-time applications is yet a challenge if the problem involves attaining a precise location in a virtual world (path-planning), and moving realistically according to its own personality, intentions and mood (motion planning). In this paper we present a strategy to implement – using CUDA on GPU – a path planner that produces natural steering behaviors for virtual humans using a numerical solution for boundary value problems. The planner is based on the potential field formalism that allows synthetic actors to move negotiating space, avoiding collisions, and attaining goals, while producing very individual paths. The individuality of each character can be set by changing its inner field parameters leading to a broad range of possible behaviors without jeopardizing its performance. With our GPU-based strategy we achieve a speed up to 56 times the previous implementation, allowing its use in situations with a large number of autonomous characters, which is commonly found in games.","PeriodicalId":315122,"journal":{"name":"2009 VIII Brazilian Symposium on Games and Digital Entertainment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131374356","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}
