19 Dec 2011 Polygon2Voxel Convert a triangulated mesh into a voxel volume Author: Dirk-Jan Kroon

*leo,
Only integer volume sizes are supported

*Tim

The x,y coordinates are aligned with the depth image, which is twice as small as the video-stream. Thus this code : x=(Pos(1:20,5)-0.5)*2; transfers the coordinates from depth to photo image.
But this is only true if the depth image and photo image are aligned, and I don't know if that is always true.

you have to compile eig3volume.c (see the example in the help) to use the function

*Ben,
The same viewpoint is not supported.

The camera in Matlab is a little bit strange, (almost) orthogonal, allows non-uniform x,y scaling and does some tricks to stay outside the rendered object. Thus porting the viewpoint to X3D gave strange results.

Do you get an error with your MRI data?, or know what is the problem?

Anyone tested yet with the new version 1.0.3 SDK released 1 February 2012 ?
04 Feb 2012 Read Medical Data 3D GUI to open most Medical file-formats: Dicom, V3D, ISI, NifTI, Analyze and other formats Author: Dirk-Jan Kroon maya

recently i have downloaded this tool.actually i have a setof 2D dicom slices and i converted to a 3D volume(.hdr) using a software,can i use your tool to read the intensity values of the voxels.I tried to use your tool,its giving error in the guifn
rror in ==> gui_mainfcn>local_openfig at 216
    gui_hFigure = openfig(name, singleton, 'auto');

Error in ==> gui_mainfcn at 94
        gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt);

Error in ==> ReadData3D at 68
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

pleases help

28 Jan 2012 B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid. Author: Dirk-Jan Kroon Gomez, Alberto

@Tripp, I have found that bug too, I think it suffice to replace M=[] with M=eye(4).

There is however another bug I am afraid. I have not gone deep into the code yet but it seems that, when doing 3D NonRigid registration only 1 direction out of 3 is computed, i.e. the resulting grid only has the estimated deformation in the third component, and components 1 and 2 remain unchanged. Ani hint on how to fix this?
