The architecture has been developed in JAVA and uses the Jason's BDI engine, being the Jason's agent-oriented programming language utilized as the means for performing the drama management and for authoring the characters' behaviors. Additionally, it makes use of ontologies to support the creation of different stories and to feed the system with story-related information. Also, the architecture can help in the development and research of interactive dramas, by including several facilities for developing the story. Finally, in order to demonstrate the use of the architecture, it has been also created a story implementation that supports some interactivity mechanisms such as a simple Natural Language Processing.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129261287","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}

Although driven by a regular uniform grid, the resulting flows correctly follow and interact with arbitrary boundary walls and internal obstacles. This is accomplished by using Jacobian matrices to relate field derivatives in the world and parameter spaces, which allows us to solve the reduced Navier-Stokes equations directly in the latter. The technique is demonstrated by using a GPU-based Eulerian Stable Fluid solver to generate real-time animations of flows confined in river-like geometry with arbitrary boundaries.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121925984","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 game is based on the fauna and flora of a desert-like field of the sand dunes in the middle São Francisco River, located inside the Caatinga biome. One of the player's goals is to manage the behavior of species of lizards that inhabit this biome, with consequences to their ecology and evolution. In this paper, we report functional aspects of the game, the features that have been developed until the present time and, mainly, the initial results concerning the game level (Level 4) in which the players will deal with the evolution of the lizards simulated in Calangos. More specifically, a simulator for Level 4 was developed and a genetic algorithm was used in order to understand what types of strategies a player may use in environments with different levels of difficulties. It was observed that favorable environments (with sufficient food and slow predators) may easily lead to an explosion in the number of lizards within the environment, hostile environments (with little food and very fast predators) lead to an extinction of lizards, no matter what strategy a player may adopt, and a balanced environment (with sufficient food and fast predators) lead to suitable survival strategies. These results are very important, from an educational point of view, because they show that there are situations in which the students will be challenged to devise survival strategies (based on an ecological and evolutionary basis) and succeed, but there will also be cases in which students will fail, no matter how good their strategy is. This failure due to hostile environments will be understood by the students if they succeeded in grasping the key concepts of ecology and evolution embodied in Calangos.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124971810","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}

This paper concludes that the \"excitement\" emotion, a key factor in order to achieve fun, is successfully achieved in the game, mostly due to the high level of competitivity provided in it.

In spite of that, it is a NP-Hard problem that can be very difficult to solve depending on the initial conditions of the board. In this paper, we propose the combination of metaheuristics with techniques from the Constraint Satisfaction Problem (CSP) domain that speed up the solution's search process by decreasing its search space and its processing time. Experiments performed with boards of size 3, 4 and 5 show that this approach allows the resolution of a greater number of instances when compared to an initial baseline.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131373945","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, not much effort has been put into accounting for the physics of sound. The simulation of the real behavior of sound through an environment, when considering the speed of sound, reflection, and absorption, is computationally expensive and is usually left aside. In this work, an algorithm that calculates sound wave propagation using a finite difference method is used and extended to present a novel approach to sound rendering. This approach reaches the objective more quickly, and the sound generated has no perceptible loss of accuracy. The approach is designed to be implemented in GPU architectures and eventually enable real-time results.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126754019","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 solutions for rendering these environments fall into two possible categories: controlling the amount of geometry displayed, and billboard-based solutions. Using the full geometry is prohibitively expensive when dense forests are needed, therefore level-of-detail solutions are commonly used to reduce the amount of polygons in the scene, however demanding more processing or increased texture memory usage. On the other hand, dynamic billboards rely on render-to-texture operations, which are also costly. We describe an alternative hybrid solution that does not use full geometry, but instead builds trees from textured billboards and simple geometry. By using a simple rule-based L-system and a small set of textures, we can achieve realistically looking visual results of dense vegetation adequate for close to far distance viewing. Our approach provides controlled tree variability and employs fewer polygons than current techniques.","PeriodicalId":354953,"journal":{"name":"2011 Brazilian Symposium on Games and Digital Entertainment","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123689989","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}
