Walk-Through Program
5 Points Walk Through GraphicThe Project:

The project was to create a walk-through for 5-Points a ( a commercial district in downtown Columbia, SC ). I planned to do this by taking many b/w pictures while walking down the connecting streets. I decided to use non-color pictures because I was concerned with download speeds.

Computational Issues:

At the time, (and is still there is no simple answer) there was nothing on the net to take care of this automatically. The problem of presenting the pictures is really not a big problem. The real issue is picking the correct picture to display. This is because one picture is dependent on the last one presented.

Consider when you walk down a street: you can go forward, left, right, or turn around. This is a simple distillation because it does not include angles of movement. For each location there would be 4 pictures - forward, left, right, back.

Now consider you take a step in one of those directions. Now, four more pictures are needed to describe that location. You take another step and four more pictures are needed.

16

That's 4 steps and you need 16 separate pictures - and for each one of these pictures you need 4 more! You can not go far until naming and organizational issues of the pictures gets very complicated.

The problem is to create a graph where the nodes represent the pictures. You then write the code for this algorithm.

Conclusions:

The problems for this project are not the pictures or converting them to Java code navigational buttons. This is simple coding. The real problem is mapping a graph that contains a good portion of the area you want to traverse. Afterward the algorithm should be apparent.

Like I mentioned - this is still in development. Click here to go back.
