Sunday, September 10, 2006 11:54 AM Terrain Visualization

As part of my research I've experimented with a number of terrain visualization techniques. I typically use GLSL Shaders. These pictures use contour based rendering technique which changes the colors based on height and includes contour lines at various intervals. In addition, I've used a technique which was developed by a colleague of mine in the University of Calgary Graphics department, which does edge detection on the GPU.


In my research I am taking a look at the usefulness of Multiresolution details for synthesis purposes. One of the applications is Iris Image Synthesis, and Terrain Repair. So I've built a program which uses Chaikin Reverse Subdivision Filters, developed by my supervisor Dr. Faramarz Samavati, to reduce the resolution of SRTM terrain. These pictures are renderings of some terrain along the California coast at varying levels of resolution. The plan is to get a good friend of mine to sketch these onto some canvasses and my wife will paint them for my office.


Speaking of thesis based work. I should get back to writing. And my wife is here, continually reminding me of that fact. It's too bad that she's right.

11:29 AM Javascript Inheritance

I can understand that Javascript itself doesn't have built in classical-inheritance. It's a dynamic language, and it allows people to build their own object models.

What I don't understand is how Prototype, and Scriptaculous get along without it. Thankfully Dean Edwards has come to my rescue and provided me with exactly what I wanted: Base.

Mike and I finally got something done out of one of these brainstorming sessions. Our idea of implementing a chess board has been released as version 1. I didn't think that I'd be quite so excited and nervous about doing this. It's a good idea right? ;-) The emotions must come from this being our first time releasing something into the wild. I know that I'll be loading the page a few hundred times a day looking for new hits.
