Volume rendering in Matlab using inbuilt GUI functions

[physical101]

Hi there.
I have become a bit stuck with a little project I am working on. I have a series of RGB Tiff images which I have loaded into matlab, over 120 separate images in total. I am hoping to use the functionality of MATLAB to render a volume by stacking each of the 2D images one top of another. I would like to in MATLAB define a cube where at each z position there is a different image. I have managed to render grey scale values in the z direction but I loose most of the information I was hoping to gain from a 3D model.

What I would like is a GUI built which has a sliding scale at the bottom to go from 0 to 120 in the z direction and display the different images at the different locations.

This is just a start and I would like to develop the program much further. Does anyone know of a good place to start?

Any help would be great guys

p.s. I don't think MATLAB is built for true colour image volume rendering but I like the language and it is very easy to distribute the code to others

Hi Physical101,
It sounds like you are trying to create a 3D volume from 2D images. You could try using the MATLAB function "imshow3D" which allows you to quickly visualize 3D data. You can also use the vol3d function to create a 3D surface plot of the RGB images. Alternatively, you could try using the isosurface function to create a 3D mesh from the RGB images. It might be worth checking out the MATLAB documentation for more details on these functions. Good luck!
