Voxler can calculate volume from an Isosurface module or a FaceRender module. With an Isosurface or FaceRender module is selected in the Network Manager, click the General tab in the Property Manager. Expand Isosurface or Facerender respectively. Check the box next to Compute Volume to display the volume values. The Isosurface will display the value above and below the specific isovalue. The FaceRender module shows approximate volume which is controlled by the blocks that are visible.
Voxler 1 and 2 do not calculate volume directly, but can export slices to the Surfer [.GRD] file format.
- In Voxler, save data as [.GRD]:
- Choose the File | Save Data command to export a uniform lattice to the Surfer Grid format. The exported lattice has a "z" dimension of one, i.e., the lattice is two-dimensional. If an input lattice with a z dimension of greater than one is exported, then Voxler prompts the user to save multiple slices into separate [.GRD] files.
- If a multi-slice uniform lattice is output to a [.GRD] file format, it is output as a series of slices in the Z direction. The Select Slices dialog appears and the user is prompted for the range of slices to output and a file name template that adds the slice number to each generated file name.
- In Surfer, calculate volume:
- Choose the Grid | Volume menu command to calculate the area above a certain level, and multiply it by the thickness of the slice to get the volume.
- Repeat for each slice.
- You could automate the task with a script in Surfer.
