Visualizing OpenCL computations within OpenGL

admin — Sat, 06 Aug 2011 14:17:57 +0000

I've been fiddling with OpenCL computations for different projects in the past. One such project is the implementation of a specific triangulation algorithm for a structured light measurement system. The other one is a parallelized implementation of a 3d binary … Continue reading →

Interactivitiy with Mayavi and python callback

admin — Mon, 22 Nov 2010 23:31:37 +0000

Today i found out that i may use figure.on_mouse_pick(function) to get a callback on a mouse_pick on mayavi-objects and it opened up a whole new way of dealing with mayavi-scenes. Right now, i'm trying to do a semi-automatic point cloud … Continue reading →

Residual of planefitting using svd

admin — Sun, 24 Oct 2010 22:58:04 +0000

Note to self: Find out about residuals of planefits using singular value decomposition. And while you're at it: find out, how least square fitting works with singular value decomposition anyhow. Right now - as with any transformation matrix bigger than … Continue reading →

Trying out Python for image manipulation and matlab-alternative?

admin — Tue, 21 Sep 2010 13:34:49 +0000

Learning new languages can be sometimes a little bit frustrating. Mostly, because you not only have to learn the syntax and conventions of the language but mainly because initially it's hard to know, what kinds of libraries are available - … Continue reading →

Here is a nice article describing the problems that rise due to the methods used in nowadays computers to calculate simple mathematics. Interesting read.

iRobot explores new ways of robotic transition

admin — Mon, 19 Oct 2009 10:43:32 +0000

With the use of mechatronically controllable flexible material, the shape-shifting robot created by iRobot can actively roll around in order to get from one place to another. Interesting and long-overdue transition mode.

More about it.

Zoom into Human Skinvon Weird_Weird_Science Nice visualization of the use of multiscale measurement systems. Used sensors include a simple video camera, an opto-microscopic camera (maybe a confocal microscope) and i think they had to use an electronic microscope for the … Continue reading →

Nice Fourier poem

admin — Thu, 09 Jul 2009 07:56:06 +0000

A poem written in honor of the ever-enlightening Fourier-transform, which is often hated by students, mainly because they don't know what it means.. Here is to the Fourier-transform:

One day in a land far away
Some mathematicians at play
Found a transform of convenient form
The basis of physics today.

Creating Gray-Code sequences using gimp

admin — Mon, 15 Jun 2009 09:00:32 +0000

I needed to implement gray-code sequences for a fringe projection system i'm trying to build. To avoid hard to understand and not really intuitive C-code, i used gimp to produce the projection images. In this article i'm going to document the code used.
