How to plot 3D image in MATLAB?

Hello, I have a matrix containing reflectivity of the 3D image of a Millimeter wave imaging system. I want to plot 3D image such that pixels having reflectivity lower than a threshold are not shown. The final image must be something like this:

How can I do this in MATLAB? Any help would be appreciated. Thank you

volshow(Image.*(Image>=threshold))

There are also a number of 3D viewers offered on the File Exchange.

Is not it possible to show intensity of image using colorbar?

Is there any other function? It is not the same as the image shown in the question.

The colume viewer doesn't seem to support a colorbar, but I'm not sure a colorbar makes sense for a 3D rendering. It is more than just the RGB color values that affect the appearance of a voxel. It's the transparency values as well.
