Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich
Feature Preserving Continuous Level-Of-Detail For Terrain Rendering, Lucas Jay Shinkovich
Graduate Theses, Dissertations, and Problem Reports
Despite the vast processing power of modern GPUs, rendering terrain geometry at sufficient frame rates is still a very difficult task. This is mainly due to the large terrain data that must be managed, displayed and modified at high frame rates. While traditional level-of-detail algorithms for terrain utilize most of the CPU and a fraction of the GPU, our algorithm exploits the parallel processing capabilities of the GPU. We represent the terrain geometry as a set of geometry images which allows us to apply image processing techniques to preserve terrain features during level-of-detail transitions and to render terrain that has …
Computer-Assisted Learning Of Japanese Kanji, Adam D. Horne
Computer-Assisted Learning Of Japanese Kanji, Adam D. Horne
Graduate Theses, Dissertations, and Problem Reports
The purpose of the program described in this problem report is to assist learners of Japanese kanji in remembering the order, direction, and number of strokes for a given kanji. Using OpenGL and the Open Haptics toolkit, the program allows the user to both see and feel the kanji. Using a PHANTOM haptic device, the user can trace the different strokes using a height map of the kanji or following arrows that show the direction and order of strokes.
Information Dissemination By Compounding, Bohe (Bob) Wang
Information Dissemination By Compounding, Bohe (Bob) Wang
Graduate Theses, Dissertations, and Problem Reports
Gossiping and broadcasting are two problems of information dissemination. In gossiping, every point in the network knows a unique item of information and needs to communicate it to all other points. Most of the recent interest in gossiping is due to its importance in the area of network communications and other areas of parallel and distributed computing.;Determining precisely the values of the minimum number of edges in a gossip graph is known to be a very hard problem. Very few values are known in the general case. G. Fertin and R. Labahn[Fer00],[FL00] used the k-way compounding method to construct gossip …
Mechatronics For Sophomore-Level Mechanical Engineering Students, David Thomas Morris
Mechatronics For Sophomore-Level Mechanical Engineering Students, David Thomas Morris
Graduate Theses, Dissertations, and Problem Reports
As mechanical product designs become more complex, integrating electromechanical components with embedded control circuitry, the need for engineering graduates with a diversified educational background in multidisciplinary applications has been recognized within many facets of industry. The focus of this research was to create a series of laboratory experiments and a capstone project based on a survey of literature from current educators that could be used to introduce sophomore-level mechanical engineering students to fundamentals in the field known as "mechatronics", which incorporates the traditional disciplines of mechanical, electrical and software engineering. The lab exercises utilize the Handy Board microcontroller from MIT …
Four-Stage Activity-Based Costing (Abc) System Modeling And Computer-Based Application Design, Jianxin Zhu
Four-Stage Activity-Based Costing (Abc) System Modeling And Computer-Based Application Design, Jianxin Zhu
Graduate Theses, Dissertations, and Problem Reports
A Four-Stage Activity-Based Costing (4ABC) model and a computer-based system are created in this research to demonstrate the ABC cost allocation process. 4ABC uses four different levels of activity cost driver to allocate the cost from resource to product. These cost drivers are Resource-to-Department Cost Driver, Department-to-Function Cost Driver, Function-to-Activity Cost Drivers and Activity-to-Product Cost Driver. CoA is then categorized into four different activity levels: Department, Function, Activity and Product. The goal is to estimate how much cost represented by activities that a certain type of product absorbs. 4ABC model can trace both indirect cost and direct cost together at …
