WITH DODECAHEDRON THREE DIMENSIONAL DIGITAL LOCK

Abstract

With this study, the Android Studio development environment and Java language in three-dimensional space, three-dimensional It can be easily applied to the user with graphics and a reliable solution with the number of solution combinations.  It is aimed to create a digital lock program.

Graphics and Rotation: This application running on Android devices has been written successfully of the screen The corners of the regular dodecahedron placed in the middle are indicated with different colors a desired moving from one point to the other and a white line between the marked points occurs.

Point tracking: It can move the corner points of a certain range to the center of the field of view and record the order of the link with the next corner point.

In the current development, the screen lock pattern cannot be drawn with the physical buttons while the app is running.

The application also used SDK version 23 and the corresponding Android version is 6.0 (Marshmallow). Devices running below 6.0 may experience graphics scaling and color problems. 

Nby expanding the number of point-to-point combinations to three-dimensional and more vertices A related graphical discussion presents a workable solution based on nine point pattern drawing. A screen lock will be created by combining six dots with nine dots.  will offer the number of combinations equivalent to the screen lock. But when the seven dots are combined The number of combinations to be formed is much higher than the nine-dot pattern drawing screen lock system is high. In the observation of a second person with the number of combinations and three-dimensional movement, it is reliable because it is not an easy-to-remember lock.
