There are many rendering algorithms used. Two of the most famous algorithms are Gouraud Shading Algorithm and Phong Shading Algorithm. These algorithms handle location of light source, location of the camera, and surface reflection properties in different manners and produce different results. Their computational complexities are also very different; Phong Shading being very complex compared to Gouraud Shading. In this talk, the rendering problem is analyzed using 3-d geometry to see how location of light source, location of the observer, and the surface reflection properties play their role. The equations for the two shading algorithms is derived, the computational complexities of the algorithms are compared, and an adaptive shading scheme is presented that chooses between computationally complex Phong Shading algorithm to render the parts of a 3-d object where it is really needed. For other parts of the 3-d object, computationally simple Gouraud Shading is used. This type of adaptive shading scheme has been in existence for some time. However, the algorithms for selection between two rendering methods are not very robust. A new algorithm, developed by the author, for such selection is presented. The comparative results of existing algorithms vs.. the new algorithm are also presented.","PeriodicalId":276741,"journal":{"name":"2005 International Conference on Information and Communication Technologies","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115647401","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}

It covers the major challenges which usually hinder the successful electronic business functions. Due to the magnitude and growth in e-culture, the need for such studies has become very important but there is a still lot of room available to have theoretical and empirical work on the topic. This paper investigates the impact of technological size and organizational complexity of IT systems. Moreover, the paper also focuses on the study of Major IT issues from the individual perspective and organizational exposure with substantial and diverse involvement of ERP, DSS and MIS in Electronic Business platform. The paper comprises on four main sections: First is about the introduction of IT systems concerning Electronic Business environment. Second is about the success and failure phenomena of electronic business. Third section relates to the detailed comparative analysis among major IT systems and Fourth part is followed by few suggestions and conclusion as well.","PeriodicalId":276741,"journal":{"name":"2005 International Conference on Information and Communication Technologies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126688043","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}

In this new architecture GAIA layer is embedded in the RTI, thus creating active space in distributed operating system (ExRTI). This architecture promotes physical spaces with hundreds of specialized embedded devices that increase productivity, alleviate some specific everyday tasks and provide new ways of interacting with the computational environment. Physical spaces become computer systems, or in other terms, Active Spaces. However, these Active Spaces require novel system software capable of seamlessly coordinating their hidden complexity. Our goal is to extend the RTI model in order to allow interaction with physical spaces and their contained entities (physical and virtual) by means of a single abstraction called Active Space, with this architecture mobile node can also take part in the simulations. When communicating between different mobile agents it is important to encrypt communication information between agents for the security of the network intrusion detection system itself. During the agents on different layer or on the same layers, communication information is easily to be monitored; intercepted and modified because of the exposed position that agent lies in.","PeriodicalId":276741,"journal":{"name":"2005 International Conference on Information and Communication Technologies","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131327215","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}

With the advent of the Internet and related Technologies, all barriers have been broken down and the world has become one large Global Village where doing business across the world has become as simple as doing business with ones neighbors living next door. Information Revolution has dramatically magnified our ability to acquire, manipulate, store and communicate information and conduct business though hyper-technology and open systems architecture of the Internet. While this provides all the facilities to conduct business smoothly and quickly it has also created a threat to the users of Hyperlink to engage in ethical and unethical business practices electronically anywhere in the world. There are Ethical Philosophies that most religions talk about, ethical values and models that guide the ethics of conducting business. These values apply to Information even more so, as now information is very easily available and mis-utilization of this information leads to very serious consequences. This paper looks at the Ethical and societal dimensions of IT and ethical principles governing IT and finally how IT is effecting the lives of everyday man, especially in the privacy realm. Pakistan is practically in the infancy of global e-business thus faces this threat even more then the other countries. This paper first looks at the ethical and unethical issues and then how the Pakistani are dealing with it. What are the youth learning and how are they spending most their leisure time.","PeriodicalId":276741,"journal":{"name":"2005 International Conference on Information and Communication Technologies","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130783015","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}
