This was my final project for the course Geometric Modeling in computer graphics taught by Dr. Richard Zhang in Spring 2012. The algorithm and the results can be found here.
Q. How to run the executable?
A. Run the shell script named "runThisScript.sh". This will do everything for you. It has qmake, make and also adds path to the libraries which is required during the run time. Just running make outside won't work. To clean the object files use $make clean. I am using igraph and libQGLViewer which lies inside usr directory.
Note:- You need to make sure the library has the correct path. Have a look at A2P6.pro for more information.
GUI:- Important:- The software now only takes .off files as provided under the mesh benchmark paper. I am attaching some of the files with the code. You can download more from here.
After running the shell script you will get one window in which the mesh will be rendered. It has two drop down menus at the top left corner viz. file and operations. For this project, I have added three more options under
operations menu which have different shading(smooth/flat shading) and wireframe option. It has simplication option as well. Here are options added for running the segmentation algorithm.
1)Segmentation:- By the clicking this you will get a pop up window asking for the three input parameters. First two are the two threshold values for adding and deleting edges. Both values are between 0 and 1.
The third is the number of iterations for the fixing artifacts part.
After running the segmentation algorithm, you might wanna run the fixing artifacts once more. If you set the first threshold value as -1 and run it again. It will only run the fixing artifacts algorithm.
2)Load segments:- Load segments loads .seg file, which provides segments for different algorithm. These are files in the set of files provided by the mesh benchmark paper.
3)Refresh Colors:- After generating or loading the segments, you might not get ideal colors for viewing. Just click on refresh colors again and again, till you get better colors.
