So far we do not have such a function, but because you can export (save) the respective structures, it should be fairly easy for you to write such a function, such as estimating the volume of from the neuron structure (swc file). You can use the V3D’s Matlab fileio toolbox to read the swc file and compute from there. Or, if you use C/C++, you can write a V3D plugin to do so (the examples are downloadable online).

Hope this helps.

Hi I am fairly new to v3d and am using the software to view blood vessels. I have found that I am able to either create a surface object (create surface from associated image) and determine a vessel's surface area, or I can create a neuron structure (right click/stroke to determine a marker/3d curve) and determine a vessel's length, howerver, I am unable to use either of the two methods to do both at the same time, nor can either of the methods determine the volume of the object/neuron. Do you have a newer version of v3d with any/all of these capabilities?
