5. My Solution Develop a program that sorts, analyses, and displays data. Develop a program that sorts, analyses, and displays data.

6. Priorities Good sorting algorithm Good sorting algorithm Good graphical displays Good graphical displays Meets requirements of client Meets requirements of client Robustness, Modularity Robustness, Modularity Completed program Completed program

7. JCluster Written in C++ Written in C++ Uses OpenGL library for 3D graphics Uses OpenGL library for 3D graphics Clustering Algorithm Clustering Algorithm

8. Why C++ Documented as still the “faster” language Documented as still the “faster” language Allows for Object-Oriented design Allows for Object-Oriented design Works very well with OpenGL graphics Works very well with OpenGL graphics

9. OpenGL Widely used graphics library Widely used graphics library Allows for 3-dimensional graphics display Allows for 3-dimensional graphics display Language very similar to C++ Language very similar to C++

10. Program Design 4 Main Parts: GUI, Algorithm (Back-End), I/O, and Graphics 4 Main Parts: GUI, Algorithm (Back-End), I/O, and Graphics

11. GUI Created using MFC as part of Visual C++ Created using MFC as part of Visual C++ One of many potential designs One of many potential designs

12. Algorithm Euclidean Distances used Euclidean Distances used Variables Standardized Variables Standardized Admittance based on centroid distance Admittance based on centroid distance Variable Reduction on high-dimensional graphs Variable Reduction on high-dimensional graphs

13. Back-End Procedure Data comes in as streams on numbers Data comes in as streams on numbers Converted into Peak classes Converted into Peak classes Peak variables are given values Peak variables are given values Peaks are sorted into clusters Peaks are sorted into clusters

14. Graphics Clusters of Peaks are sent to graphics object Clusters of Peaks are sent to graphics object Clusters are color coded Clusters are color coded Window is 360 o rotation around X and Y-axis Window is 360 o rotation around X and Y-axis

15. Log File File gives text representation of data File gives text representation of data Identifies each cluster and the number of peaks Identifies each cluster and the number of peaks Average values within clusters Average values within clusters Factors taken into consideration Factors taken into consideration Date and Time Date and Time
