MATLAB: Showing inner volumes of any filled 3d volume.

cylinderfilled volumeImage Processing Toolboxinner part of volumesphere

Hello all, With having filled volume say a sphere or cylinder , I want to show their inner volume part which is some portion of 3D shape , how it can be done ? for example- in daily life we have an apple , we cannot see any inner part until we slice that .After cutting we can see slices and take one of them which is part of apple . thank you

MATLAB does not have superior 3-D volume visualization methods. About all you can do are cutaway views and isosurfaces. To do what I think you want to do, take a look at the slice() function. Also type "volume visualization" into the help search field and find other related functions.

Just have a 4-D matrix where the 4th dimension is the slice number.

So it sounds like you have a binary three dimensional volume that you are essentially summing to get the volume of the points? If this is correct, I would first calculate an isosurface of this using isosurface:

doc isosurface

Then with vertices from the isosurface, calculate the convex volume using convhulln. To calculate the non-convex volume, you can do what you're doing now which will be an overapproximation or you could convert the mesh to convex tetrahedra and sum up their volumes.

This might help with that:
