Realtime fluid dynamics on iPhone and iPad
|
This is the first iPhone (and iPad) application I made.
It is a realtime Navier Stokes equation solver for the iPod, iPhone or iPad. You can draw colors on the canvas using a single finger. When using multitouch gestures you can twist and twi... |

Marker Detection for Augmented Reality Applications
|
Many augmented reality applications are based on the detection and reconstruction of the orientation and position of some markers.
First step is the detection of black-on-white squares in an image. We implemented (just for fun) such an algor... |

Yes, it is running in real time using my iSight on a MacBook Pro (640x480) and my iMac (1280x1024). At the end of the blog post you can find a video of the marker detection in action. This video was captured while the algorithm was running in re... |

rendering with distance fields
|
Two weeks ago I spend 7 hours to implement a very simple distance field renderer using de Go language (as an experiment and just for fun). You can find my results here:

portal engine visibility math, alternative approaches
|
'My' aproach works best with large sectors. The sector's can be non-convex (unlike descent) if you render the sectors using z-buffering which is pretty standard today :-).
I think this method is a very good for 'hardware accelerated' rendering becau... |

portal engine visibility math, alternative approaches

You can also project the vertices of a portal to screen coords and calculate the bounding square.
When you draw the next sector you clip the bounding squares of the portals with the bounding square of the first portal.

Doom 3 .map question
|
the .proc files contains the 'level' data (sectors and portals) and some pregenerated shadow volumes. The .cm file is used for collision detection.
The level is rendered using a portal-based visibility algorithm.
I wrote some demo's reading the .pr... |
