Dear ALL,

in 3D space, (e.g., x=1:1:100,y=1:1:200,z=1:1:400)

at every combination of (x,y,z), there is a W value

it is like If I have a 3-D object, which has a nonuniform mass density w at coordinate (x,y,z)

how can i visualize the mass density, w(x,y,z), of this 3-D object?

Thanks a lot.

Andy

help isosurface

Hi,

You can use MATLAB isosurface function.

However MATLAB isosurface function has a lot of problems for complex data.

I have created a program that renders exact error-free surfaces from 3-D voxel data, such as from MRI, CT Scan.

The following is the link to the discussion thread

http://www.mathworks.com/matlabcentral/newsreader/view_thread/268226#755017

You can download the program from
