Ray tracing is a very popular rendering algorithm in the field of computer graphics because it can generate highly-realistic images from three-dimensional models. Unfortunately, the computational cost is very expensive. To speed up the rendering process we present both static and dynamic scheduling (balancing) strategies for a multiprocessor system. Hence, the load balancing among the processors is the most important problem in parallel processing. The implementation of the algorithm is based on a modified octree structure.

Many applications have been developed for Virtual Reality (VR) during the new wave of VR technology. These new technologies make it possible to create 3D meshes in a virtual environment in real time. However, the usability of VR as a modelling tool is still a new area of research. This study’s research created a VR 3D modeling tool that will provide the user with tools to interactively generate and edit 3D meshes in real-time and teach the users how to create 3D models. The study had two groups of participants, one group used Autodesk Maya, and another used the VR modeling tool. All participants were from Purdue University and all data was collected in the Polytechnic Institute. Both groups were given a task to create a teacup with the time it took to complete it recorded. The VR tool was evaluated with a SUS (System Usability Scale). The participants provided feedback and rated how difficult it was to use the application. With the SUS, it was determined that the application did not meet the industry standard average score of 68. However, further analysis on users’ responses showed many areas to improve in the application. A few recommendations for future research include implementation of multi-selection, a undo and redo feature, and improvements of how the user interacts with the 3D meshes.

In the field of Computer Graphics, Ray Tracing has so far been the the best algorithm for rendering of realistic three dimensional images created by mathematical models. Ray Tracing is also known for its very large computation times, where the computation depends on the picture resolution, the number of objects and the complexity of the scene.

The FunGraf project was commenced with two broad aims: to explore the suitability of functional programming for graphics and to test the usability of the functional I/O models that have evolved recently. / Master of Science

Most current commercial automated IC inspection systems use gray-level or binary images for IC defect detection in spite of the fact that color permits defect detection where gray-level information is insufficient. Three color image processing techniques including the spectral-spatial clustering, principal components, and hue-saturation-value (HSV) color features have been investigated to evaluate the usefulness of color for IC defect detection. The AMOEBA spectral-spatial clustering algorithm, an un-supervised color segmentation approach, with a sequence of image processing procedures resulted in segmentation results with high accuracy and discriminated successfully an isolated and homogeneous defect with an unique color signature. The principal components transformation and the HSV color features, two color enhancement/separation algorithms, have proven useful for enhancing and isolating weak spectral signatures in the defect regions. The results of this investigation into the use of color are promising.
