01 Apr 2014 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*CdC
This software is only a small demo I wrote for fun, and never tested with more than one user.

Probably it is also not really suitable for multiple users, because Matlab is in basis single threaded.

A solution is using a real HTTP server like Apache, in combination with PHP (see easyphp.org).
Then compile your matlab-code to a executable and simply parse the user inputs/outputs to that executable through PHP.

21 Feb 2014 Patch Software Render Patch Software Render with Phong-shading, shadows and textures Author: Dirk-Jan Kroon

Note, in this version is the following bug
Line 34 in renderpatch_shading.cpp:
if(L[3]==0)
Is a bug, must be:
if(LP[3]==0)

Thank you, there was a bug which I solved by removing abs from the eigenvalues. This version will probably be online in one or two days.

11 Oct 2012 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*Filipe S.
A Matlab GUI/Figure is user-interface thus client-side, this is a webserver thus server-side.
The only way to do client-side things like showing a GUI, is manually coding the GUI in javascript, html and css

30 Jul 2014 Kinect Matlab Microsoft Kinect, OpenNI wrapper, Skeleton, Depth Author: Dirk-Jan Kroon Ulrich

I have a few questions:
1) What is the difference between OpenNI1 and 2?
2) How do I change the Picture Size?
3) Why are mxNiSkeleton and other missing in OpenNi2?

Yes, Microsoft KinectSDK v1.8 works as well.

Does it work with Microsoft KinectSDK v1.8?

29 Jul 2014 Dicom Tags Read and Write Read / Write raw Dicom tags with large dictionary, for small file manipulations, like anonymize Author: Dirk-Jan Kroon Scott

I'm running into a situation where the ReadDicomElement function fails to read the PixelData because the defined size is -1 (line 139 of ReadDicomElementList.m). A comment in the calling functionReadDicomElementList says it will "Read all tags until the PixelData is reached" but it proceeds to read until the end of the file is reached. How can one handle the OB-type PixelData element with element.length = -1?

29 Jul 2014 Matlab 3D figure to 3D (X)HTML Converts 3D objects of a Matlab figure to XHTML embedded X3D file. Interactive 3D website graphics. Author: Dirk-Jan Kroon carlosgeldo

My problem is solved, to set options you must create

options = struct('output','both','height',500,...); %names in help or in figure2xhtml.m
figure2xhtml(options,h) % "save as" window is opened
