Viewing EIDORS images with Mayavi

Since, the Matlab graphics functions for 3D visualization are fairly poor, EIDORS provides the capability to work with VTK files, which may be viewed with Mayavi.

Install Mayavi

Install mayavi from mayavi.sourceforge.net/download.html

Calculate image and save to a vtk file

The following code will save to a file fname.vtk
img= compare_3d_algs(1);
writevtkfile('fname',img.fwd_model,img)
% writevtkfile('fname',img) % IN MORE RECENT VERSIONS

Image display


Step 1: Run Mayavi. Load file. Click: File -> Load. Select fname.vtk


Step 2: Close config dialog. Click on Close


Step 3: Visualize Surface. Click: Visualize -> Modules -> SurfaceMap. Decrease Opacity. Click: Close.


Step 4: Visualize Cut - Planes. On "Configure Surface", Unclick: Scalar Coloring. Click: Visualize -> Modules -> ScalarCutPlane. Modify Angles and Distance to suit. Add more CutPlanes to suit.
