Abstract

Along with the growth of Petra Christian University, more college students and guests will come to visit this university. Petra Christian University has more than few buildings and it does not rule out the possibility that new buildings will be build later. Then, Petra Christian University will need location maps and directions to help visitors of the university find specific locations inside campus area. There are physical and digital maps of Petra Christian University, and a Final Project which displays few floor maps of Petra Christian University. But an application which especially provides an interactive map and virtual tour of Petra Christian University hasn’t been made.Thus, a system is being developed, which has two separate applications. The first application is an Android-based apllication called Petra PanoraMap, its goal is to provide interactive maps for Petra Christian University. This application provides a virtual tour for users which displays panoramic views of several locations inside Petra Christian University. The second application is a web-based application called PanoraMap Editor, its goal is to provide all data and pictures needed by Petra PanoraMap. Thus, it is needed to create a data structure that can represent Petra Christian University as a whole entity based on object-oriented approach.Tests have been performed to both Petra PanoraMap and PanoraMap Editor. Petra PanoraMap application can display panoramic views so that users can feel that they are inside Petra Christian University. It is proved that PanoraMap Editor application can produce a type of data that can readily deployed into and read by Petra PanoraMap, so that contents and panoramic photos inside Petra PanoraMap is a dynamic data.

Abstract

Javanese letter are a representative and a proof of Indonesia’s rich and diverse. Nowadays the use of Javanese language in oral and written conversation Indonesia is getting rare. Our people prefer to learn our national language or international languages such as English and Chinese. Another work to conserve Javanese letter is make Javanese letter optical recognition. Therefore, in this thesis an application that could be used in the preprocessing phase of Javanese letter recognition was developed.Hough transform and projection profile are the methods that used in this application. Hough transform is a method that perform skew detection on the document. Projection profile is a method that process segmentation.In Chapter 5 light intensity, consistency range between rows, font size and type, the difference of font weight would affect the result. The result of projection profile method can segment 77% of document with consistent range between rows. The hough transform method can detect skew on the document up to 94%.

Abstract

Rendering is the process by the end of the whole process of modeling or computer animation to change the form of three-dimensional objects into two dimensions. One popular method of rendering known today is ray tracing. Ray tracing is a technique for generating an image by tracing the path of light through pixels in the image.Ray tracing method is able to produce realistic images because it is calculating lighting effects such as ambient, diffuse and specular. Reflection and refraction of light is also calculated in ray tracing. In addition, ray tracing method is divided into two kinds, known as the tracing rays from the eye (backward ray tracing) and tracing rays from the light source (forward ray tracing).Caustic effect produced by emitting light in a transparent object. Refracted light will gather in an area so that the area will appear brighter than the surrounding areas. In previous studies, the effect of caustic applied to the primitive object, where the light checks done once per object. In this study, the object used is mesh. Checking the light will be performed on each triangle in the mesh.Results showed the greater refractive index, the more caustic effect gathered in certain areas of the body bare round, but spread on a flat and taper grounded object. The increase in the complexity of the mesh will increase linearly time. Comparison with other software shows the difference in the form of caustic effects and rendering time.

Abstract

Making mockups for display to investors often requires a very high cost, manufacture mock floater if deemed there are less suitable in the making. To overcome this age often the designers will re-create the mock-scale model if it is not in accordance with the wishes of investors. But the problem that arises is the purchase of an expensive tool visual examples, so it is not efficient in generating cost manufacturing maket.To overcome this, invented a visualization application mockups city park by using markers made of paper, so that the cost of making these mockups cheap, compared with money must be spent to buy equipment such as, trees, park benches, etc. Users can also add mockups according to keingginannya, can add objects that are free on the Internet, then choose a marker in accordance with his wishes, the User can print the even own mockups that will be used.To make the visualization process is carried out mock-long process ranging from changing color to gray, change the color to black and white, edge detection, square detecting, matching the template to print the object desired dimensions. Through the test results, it was found that the result object that is displayed on the screen is in conformity with the position marker, the downside of this process is that the process that takes a long time rendering and 3D printing process object that still has texture and recognizable marker must rectangular.

Abstract

Technology development, particularly in video game, has reached to all human life aspects. Many game developers seek not only for innovations to a more interesting gaming system, but also for added values to the game itself. Virtual reality game becomes one of the alternatives to develop the gameplay aspect. Players are highly immersed in the video game world, and convinced as if they were in the game itself. This thesis aims to make a virtual reality game with Dodgeball sport theme using Kinect and XNA Game Studio integrated development environment.The Kinect used in this Dodgeball game is meant to control a game character to follow the real one. The character moves in the same way in real life. Therefore, players will find the game more realistic, and they will feel the sensation of playing the real Dodgeball. Besides, players do not need to use a game controller. Players’ movement also become more natural in the absence of the game controller.Our Dodgeball game has gone through several adjustments, such as, each team’s players are limited to 4 people, which at most 2 of them are human players. The number of balls used in this game is reduced to 2, and before the game begins, the balls are assigned to teams by coin tosses. Dodgeball game is also packed with physics and simple artificial intelligence to enhance players’ gaming experiences in playing Dodgeball game.

Abstract

The development of technology can make human being to do a lot of things more simple. Teaching method currently has many variations so that the learning process is more alive. Learning by explaining the process which can be seen is very beneficial. Sometimes in a process, hand gestures play an important role in understanding the whole process. The use of webcam can be another alternative to digitize what is written by users. This thesis aims to digitize lecturing notes on paper using a device webcam.The system includes processes like image retrieval, paper detection, projection mapping, skin detection and removal, and processing results with threshold method. Paper edge detection process uses the method of canny edge detection. In paper edge detection, webcam image becomes image with white color for area of paper. Projection mapping process is used to map the image with trapezoid shape of paper into image with rectangular shape of paper. Skin detection process uses HSV and YCbCr color space. In skin detection process, hand which still appears in image becomes image without hand. The application was created using the C# programming language with Visual C# 2010 as its IDE.The experiment results indicate that the color, ink thickness, threshold value, height of the webcam, size and distance between scratches, and lighting level will affect the final outcome of the application. In addition, the hand’s position during the writing may cause a shadow on the paper. The best result of all methods which have been tried is the result of the threshold method.
