Calculation of volume from mesh

Post by Ingsayyad »

I have two mesh objects. I need to get change in volume.
1-I can get their difference. Now question is that is there method to convert this diffrence into volume.
2-Can I simply get volume from mesh. Then I can calculte Delta_Volume=Volume1-Volume2
3- Can I convert mesh into solid. So, that I can do further in Autocad.

Re: Calculation of volume from mesh

I've just added a method to compute the volume of a mesh. However, the result is only valid if the mesh is closed (what you call a 'solid' I guess?).

For the records I used the following method:

I'll try to see later if we can extend this algorithm to deduce the volume of displaced material (i.e. a mesh with an associated scalar field) but I'm far from sure ...
