A 3D volume is constructed from a stack of 2D masks (slices). How to color each slice based on the area of the object inside. Suppose the volume is a trunk.

Do you want all the pixels selected by the mask of a slice to be the same color? Or do you want to shade by value, different brightness of the color according to pixel value?

colorval = repmat( sum( sum( masks3d, 1), 2) ), size(masks3d, 1), size(masks3d, 2), 1 ) .* masks3d;
vol3d('CData', colorval', 'alpha', double(masks3d))
