New article about the midpoint method
Op 2012-05-21 12:07:27 gepost door Wouter Buddingh'.
Recently I have written an article about the midpoint method. It gives a proof of its correctness and it discusses how to apply the midpoint method for second order ODEs.
Also, some aspects of implementing this integrator are discussed.
The article can be found here:

Linear and Quaternion Algebra Template Library

Hello dear viewer,
Below, you can find a link to a C++ template based algebra library I wrote. With this library, you are able to manipulate small matrices e.g. 16x16 entires, vectors and quaternions:
Linear and Quaternion Algebra Template Library
It is template based, in such a way that you have to specify the size of the matrices/vectors at compile time. This gives some performance gain. I have encountered several other libaries (usually included within some library, which I consider to be inferior). Note that this doesn't always hold. There are professional libraries, that do better in the general case. This library is supposed to score because it it simple. You can use it to build a game, or a physics simulation (that's where I use it for). A nice thing about this library is that it is contained in a single header file.
Regards,
Wouter
Renewed wosabi.com

Hello everyone,
Wosabi.com has been renewed.
This site has mostly been translated to English.
You might find some Dutch here and there. Sometimes this is intentional, sometimes it is not.
I would guess that many non-Dutch reading visitors would press the back button when they would find a non-English site. I usually leave when I find a German page.
You may also have noticed that the domain-name wosabi.com simply forwards to wouterbuddingh.nl.
Regards,
Wouter

Dag iedereen,
Sinds vandaag is deze website ook te bereiken via
www.wosabi.com.
Met vriendelijke groet,

Een gelukkig nieuwjaar

Disappointing quality stereoscopic
Op 2011-12-18 09:08:58 gepost door Wouter Buddingh'.
The output of the stereoscopic application is a bit disappointing. The algorithm only gives good output in example cases. I was planning on releasing stereoscopic v 1.3 building on the same poor basic algorithm. If there will be a new version, it will be based on a new approach.
Stereoscopic Version 1.2
Op 2011-11-02 03:11:30 gepost door Wouter Buddingh'.
A new version of stereoscopic has been released.
You can find it under this link Stereoscopic V 1.2.
Both the algorithm and the user interface have changed. The algorithm now supports a two-dimensional search window, vertical parallax and RGB matching.
Depth extractor update

The program has been updated and test data has been added to the site.
See Stereoscopic v 1.1 .
Depth extractor (Stereoscopic)
Op 2011-10-24 09:28:46 gepost door Wouter Buddingh'.
Recently, I wrote a program than tries to extract the depth from a left/right image pair.
I searched the web for such an application, but I was unable to find a free one.
The quality of the depth extraction depends highly on the quality of the input pictures. In ideal situations, i.e. rendered images conforming to certain criteria, the algorithm preforms pretty well.
You can find it in here: Stereoscopic v 1 .
Prototype Engine v 2.1
Op 2011-10-17 11:43:34 gepost door Wouter Buddingh'.
Het programmatje bleek niet te werken op enkele andere videokaarten. v 2.1 zou dit als het goed is moeten fixen.
Tevens is er een Linux x64 binary meegeleverd.
