Floor casting After I added a quick prototype of floor-casting, it was obvious the technique I’m familiar with (from the permadi tutorials) would be too slow for the android version. There is definitely a way to speed this up, but I’ve removed the floor casting for now until I come up with an alternative method [...]

Switch to LibGDX I really wanted to make my raycast engine compatible with cell phones, but I also wanted to be able to play it on my own machine. Because of this, I decided to switch my raycast engine from QT over to the java based LibGDX. This allows me to run the same project [...]

I’ve recently started building a raycasting engine using QT. Here are my (simple) results so far. Implementation I created a View based on QGraphicsView. I then added a scene to this (inherited from QGraphicsScene) which contains 240 rectangles. Each rectangle represents a slice from the raycasting algorithm (one ray = one rectangle). The math was [...]

My girlfriend and I recently embarked on a trip to Washington DC for the first weekend of spring break. We managed to do this for under $300 by staying with her friend, Xiao Yu, too. In fact, our final bill was: $140 gas both ways + $90 food + $10 transportation (subway tickets) + $18 [...]

I’ve been working quite a bit with WebGL for one of my research projects, so here goes: Skeletal Animation I want to see a graphics library built on top of WebGL that supports rigged meshes. For instance, there was a blog post recently about combining the Kinect with WebGL, but there is currently no easy [...]

If you’re having problems running Haptek Player, or it’s running super slow, on Windows Vista or Windows 7, it’s probably because you have a multi-core system. The fix is to make Haptek run on just 1 core.
