Today I had a presentation to give on Case Studies for File Sharing incidents. To make the presentation interesting I thought I’d try out my Rough Edges Editor and see how well it performed in a real world scenario.

Overall it went pretty well but there are big things I wish I would have done and/or not done in the engine. It taught me a lot of things to look for and to change the next time I take a stab at a 3D engine.

I’ve built a small application for use in encrypting / decrypting cryptography ciphers. For now, it covers the Shift Cipher, Hill Cipher, Affine Cipher, and the Substitution Cipher. Each cipher logs its process giving a step by step procedure showing the work completed. It was created with C# and therefore requires the .net framework 2.0+ to be installed.

EDIT (2/23/2010) – Fixed Inverse 2x2 Matrix in the Hill Cipher. Inverse determinant wasn’t being calculated to determine the inverse.

For my CS 5611 (Advanced Computer Graphics) class at Michigan Tech we were asked to create a program that displayed some common problems with lighting. This is my interpretation of the exercise which is almost identical in function as the educational tool PBR-Tutor. It uses MFC and OpenGL written with C++.

So I got a little bored tonight and wanted to make a program. Now a little background, my roommate is constantly downloading new videos, books, and other programs to the point that I’ve always wanted an RSS feed of his folders. So, I went ahead and created a simple RSS feed with ASP.net to do this. Then I took it a step further.

I created an application for Windows that scans any network share that you want, grabs the file information in descending order of earliest creation time on the file. The program will then pop up a notification every time a new file is added to the network share (scans at a designated interval). You can then open the file from the program or leave it until later.

So, with out further ado here is my Network Share Notifier : [Download]

Just finished my xna7day competition entry.

Script Used

if (tracking.Selected)
{
        REAnimModel model = tracking as REAnimModel;
        if (model != null && model.Track != "Walk")
             model.Track = "Walk";
             model.Translation = new Vector3(model.Translation.X + 0.05f, model.Translation.Y, model.Translation.Z);
}  else  {
         REAnimModel model = tracking as REAnimModel;
         if (model != null && model.Track != "Loiter")
             model.Track = "Loiter";
}

Code Needed :

Initialize

MoveableCamera cam = new MoveableCamera();
cam.CollideWithTerrain = true;
cam.LockToTerrain = true;
cam.HeightAboveGround = 4.5F;

string rootDir = Directory.GetParent(Application.ExecutablePath).Parent.Parent.Parent.Parent.FullName + "\\Resources\\";
XmlTextReader doc = new XmlTextReader(@"C:\Rough Edges\AnimatedModelTest2.rel");
AssetManager assetManager = new AssetManager(Services, rootDir);
Helper.LoadContent(assetManager, rootDir);

scene = REScene.ReadXML(doc, assetManager, GraphicsDevice);
scene.Camera = cam;

Update

scene.Update(gameTime, GraphicsDevice);
