On Data

People talk about all the stuff we’re going to be able to do once computers are fast enough and storage is cheap enough. Sadly, I don’t think technological advances will gain us much. Taken to the limit, the digital world of computers is just the analog world that we already have. And there’s nothing easy […]

Feature 8 Post Mortem – Conor

This feature was all about using textures to modify the base albedo of the terrain in my scene. The steps to do this are not really any different than texturing any other model. I needed to upload the texture that I wanted to use, and create a new shader that would take advantage of the […]

Feature 3 – Kevin

Applying specular lighting to different objects wasn’t too hard beyond the demonstration.  I did not encounter any problems beyond what Chris showed us. http://www.youtube.com/watch?v=ED56CjCJ2Qo

The Programming Gene

My wife and I read to each other. We ran into this the other day in Daniel Defoe’s Robinson Crusoe: So I went to work, and here I must needs observe, that as reason is the substance and original of the mathematics, so by stating and squaring everything by reason, and by making the most […]

Feature 1 – Emmertac

First thing: I do not have any recording software; my laptop has been dead for some time now and I do not have a smart phone. Besides we all know you didn’t come here to listen to someone talk. Look at the other object, besides the terrain, whats the first thing that comes to your […]

Sit Down and Code

At the 2012 Midwest Instruction and Computing Symposium, visualization researcher Daniel Keefe offered a keynote presentation on data-intensive visualization. His work involves the design of novel interfaces to navigate complex data sets. Visualization researchers always have the best demos. Mr. Keefe expressed his frustration with programmers: they hear the problem and then they sit down and write […]

What’s the Best Text Editor?

Students ask, “What’s the best text editor?” When talking about superlatives like best and worst, we really have to narrow down our scope to have meaningful discussion. You simply can’t say, “They’re the best band ever!” You’ve not gone through all of time and figured that out. Even if we could travel through time, there’s […]
