Abstract

Development and competition in Indonesian University is extremely tight. Petra Christian University is also a University's with long-standing and well known to many people in Indonesia. Prospective students would like to see more clearly the shape, structure and atmosphere held at the University. Thus someone created a virtual map for Petra Christian University building by using a Head-Mounted Display Oculus Rift to display a simulation of the map Petra Christian University building. But the virtual map that has been created earlier is simply an empty simulation maps that contain only furniture - furniture and does not contain a virtual character, so that the simulation does not have any college atmosphere. So it was decided to implement a virtual character in a map that looks like a real simulation using a rule-based system.In the development of prior research program conducted every object in the form of the building, so hopefully the results obtained could resemble its original state. Giving materials to the models at the Unity are expected match the colors of the original state. Giving collision features intended to make the user cannot penetrate what as original state.Results on this program, the position and shape of character object in the building resemble the original state that existed at Petra Christian University. Time constraints in making become a major factor, so it’s cannot make the character more in detail. The whole room and the character of the building P 2nd floor has been made, there are only a few sections still incomplete, example on the large staircase of the building P and other small parts. Disadvantages of this program require computer high specification enough to run the program. This is because the resulting resolution on this program can be fairly large.

Abstract

A lot of digital images processing methods that were developed to meet the needs of digital image processing which began to appear in various fields of science. In outdoors image retrieval, often arise problems, the backlight effect, that caused the digital image processing became more difficult. Therefore digital image processing applications will be made to meet the above requirement, which is based on retinex theory.Retinex is algorithm to eliminate the effects of illumination light from front/rear, and repair colors in digital image by eliminating color lighting that can make changes in digital image. In this study, digital image processed by retinex and then flatten the contrast with histogram equalization technique to eliminate the backlight effect on the digital image. Based on the test results, the application can display digital images with the backlight effect is reduced and the detail is more visible in the area that covered with the backlight shadow. In another test with images that have no backlight and bright, after the retinex process, the results is not satisfying, the images are broken, fade color and the color changes significantly.

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

In this period of time, a photo is a common thing. Photo serves as a medium to store memories of important events around us. Mastering the science of photography requires the skill and techniques so that photographs or works produced will be good enough to be sold. However, the skill and results of good photography lack the container to turn photography as one’s income. The lack of such containers resulted in the photographs being viewed only as works of art. This causes the hobby as a photographer as well as skills in photography sometimes do not gain their economic value.So, a container is needed to facilitate the sale and purchase of photographs produced by photographers or the public. In the Photostock application also has a built-in watermark feature that can automatically add a watermark in your photos in order to avoid copyright infringement. In this application users also can chat with the photo seller.Based on the results of the questionnaire obtained for the application display quality, 60% of other respondents answered not bad and 40% of the other respondents answered well. For feature completeness, 40% of respondents answered not bad, 40% answered well, 20% answered very well.
