This tutorial provides suggestions when using the Math module.
Working with the Math module to fill between two HeightField modules:
Create the top and bottom of the surface grid files in Surfer or another program.
In Voxler, click the File | Import command. Select the top surface grid file. Click the OK button. The data module is loaded into the Network Manager.
Click the File | Import command. Select the bottom surface grid file. Click the OK button. The data module is loaded into the Network Manager.
Click the File | Import command. Select data file that was used to grid the top surface. Set the X and Y columns to the correct columns. For the Z and C columns, set the value to the top of the surface.
Select the data file in the Network Manager. Right-click on the data module and select Computational | Gridder to add a Gridder module to grid the data.
Select the Gridder module in the Network Manager. In the Property Manager, click the Begin Gridding button.
Right click on the Gridder module in the Network Manager and select Computational | Math to add a Math module to the gridded data.
Select the top of surface grid module in the Network Manager. Right-click and select Connect output lattice. Drag the connection line to the Math module and select Connect Input Lattice B.
Select the bottom of surface grid module in the Network Manager. Right-click and select Connect output lattice. Drag the connection line to the Math module and select Connect Input Lattice C.
Select the Math module in the Network Manager. In the Property Manager, change the Expression[1] to IF Z > B OR Z < C, 0, A.
If necessary, attach a Transform to the Math module using the Network | Computational | Transform command. This may be necessary to scale the Z height.
Connect a VolRender to the Transform module, if it exists, or to the Math module using the Network | Graphics Output | VolRender command. Change any properties of the volrender.
This example shows all of the data
displayed as a VolRender module.
The Network Manager contains the original data file, the two grid
files, the Gridder, Math, Transform, and VolRender modules.
Using the Math module allows you to display fill between
two surfaces (as seen below).
The resulting output is a VolRender that displays
the fill between two clay surfaces.
