This study was designed to investigate the ability of young children to use a particular computer graphics program Colorpaint and its effects on their artwork. It was conducted in two parts : the pilot study in which five children participated and the main study which involved two children. Four predictions were made. Prediction one stated that of the total number of children's interactions with the program, more would be in the category of independent use than in the category of teacher-assisted use. The second prediction was that children would use goal-oriented behavior in aesthetic decision-making and problem-solving when using the program. Prediction three stated artwork, done with computer media would be rated higher in each of the categories of "Variety within Shapes", "Variety between Shapes", "Complexity", and "Texture" than would images made with other media. The fourth prediction was that computer-generated artwork, would be rated lower in the category of "Image Autonomy" than the artwork done in other media. For both parts of the study, anecdotal data in the form of field notes, transcribed conversations, and videotapes were kept and analysed to provide insight into the children's behavior when using the computer. During the main study the children's interactions with the computer program were recorded on a checklist indicating whether they were able to use the program independently or if they needed help. Artwork made by the subjects in the main study using the computer and other media were saved for analysis and were rated by three independent judges. The judges used five criteria derived from the literature on children's art to rate each image on a five point Likert scale. Results indicated that prediction one, which stated that more interactions with the computer would be in the category of independent use, was supported as there were more independent interactions than teacher-assisted interactions with the computer for each subject. Prediction two, which indicated that children would use goal-oriented behavior in aesthetic decision-making and problem-solving when using the computer, was supported by the descriptive data collected. Prediction three, that the computer images would be rated higher in each of the categories of Variety within Shapes, Variety between Shapes, Complexity, and Texture, was supported in the two categories Variety between Shapes and Variety within Shapes. The fourth outcome predicted was that the computer artwork would be rated lower in the category Image Autonomy than artwork done in other media. This outcome was supported by the results of the analysis of the artwork. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate

Approved for public release; distribution is unlimited / Many 3D training simulations employ static, and to some extent, simplistic natural phenomena representation that often leaves much to be desired. Taking advantage of the latest advancements in computer graphics hardware allows modeling dynamic natural phenomena such as clouds. Specifically, utilizing procedural techniques and high-level shading languages, it is possible to produce considerably more realistic simulations. This thesis designed and implemented a visual simulation component, which renders convincing clouds using procedural noise-based texture mapping techniques. Both traditional rendering and shader-enabled rendering supported by the OpenGL Shading Language are utilized. This component has been included in the Delta3d simulation engine and is used to create convincing clouds in outdoor simulations while the performance penalty imposed is considered acceptable. Custom tools have been developed for easy noise texture parameterization and cross-platform compatibility has been demonstrated. / Lieutenant, Hellenic Navy

A major problem in robotics vision is the segmentation of images of natural scenes in order to understand their content. This thesis presents a new solution to the image segmentation problem that is based on the design of a rule-based expert system. General knowledge about low level properties of an image is formulated into production rules. A number of processes employ the rules to segment the image into uniform regions and connected lines. In addition to the knowledge rules, a set of control rules are also employed. These include meta-rules that embody inferences about the order in which the knowledge rules are matched. They also include focus of attention rules that determine the path of processing within the image. A third set of rules contains the strategy rules which are data-driven inferences about the control rules. They dynamically modify the processing strategy. Different rule ordering and focus of attention strategies are selected according to a set of performance parameters. These measure the quality of the segmentation output at any point in time. Experiments with the knowledge rules resulted in an optimal set based on output quality and processing efficiency. Overall system performance is shown to be qualitatively and quantitatively superior to previous segmentation algorithms.

With the advent of the computer, the world of design has been revolutionized. Many artists and designers have started to look to the computer to aid in their design processes. By using the computer, designers have been able to achieve a higher level of precision and design resolution. This project examines the processes involved in teaching the computer as a design tool to art students and faculty. By drawing on five years of computer application experience, the author has created and executed a plan for helping designers learn the advantages of incorporating the computer as a part of their design processes. This project deals with the difficulties of teaching designers the visualization and computer skills necessary for using the computer as a design tool. The project focuses upon two groups of students. The first group was comprised of advanced metals students learning MacintoshApplications. The second group was comprised of advance metals students working on Microstation, a CAD software application. / Department of Art

This Creative Project has investigated current methods being used to produce computer animation. This investigation has resulted in the creation of a computer rendering program capable of generating animation. In order for the program to be able to execute though, a model of the object to be viewed must first be specified. This is done by assembling together a series of graphic primitives that when viewed collectively, form the desired model. Next, the rendering software is told where to point an imaginary camera in space. This camera is used to focus the image found in the viewfinder onto the computer monitor. Lastly, the imaginary camera is provided with a three dimensional path to follow as it tracks its way through space. By combining this data with the rendering software, a person viewing the resulting computer animation is able to interact with the computer model. / Department of Computer Science
