Mesh Comparison - Javascript & ASP.NET service

Web page for mesh comparison

Pure JS, client-side scripting

• For the interactive servicing of mesh comparison(or retrieval), I made the web page for it using X3DOM for visualization and JS for calculation.
• It was pretty successful, and you can see the result in the below link.
• You can test with your OBJ or OFF mesh data or,
• You can download sample model from here.

• (OBJ and OFF parser may have some limitation.)

Using ASP.NET

• Soon, I realize that the client-side scripting is not enough for maintaining DB for mesh data, and shape descriptors.
• I'm not familiar with the various web technologies and choose a server-side programming method that I can develop fast-ASP.NET
• First step is develop the calculation module with C# DLL, which is just a conversion task from JS.
• Second step is designing the layout, which I'm not good at, and connecting the module with elements in the page.
• Also, one functionality added is storing the uploaded mesh data into server machine for later development.
• For dynamic visualization of X3DOM, "HTMLGenericControl" of ASP.NET was used to change the attribute value in X3D node.(Is there any performance issue?)
• You can test with your OBJ of OFF mesh data, but you should keep in mind that the DATA YOU UPLOADED WILL BE STORED IN MY SERVER MACHINE.
• (OBJ and OFF parser may have some limitation.)

Further Issues

In development

• The postback harms the UX...

• Performance itself seems worse than JS

• Hopefully, I will solve the problems by modifying the structures.

• Model DB displaying, selection and retrieval.

In methodology

• I didn't clearly understand the Histogram --> PDF part yet.

• Several approaches on normalization, bin width selection and PDF comparing.
