General Module Function
The Interp data module interpolates nodal data from a 3D or 2D field to either a 2D mesh or 1D line. Typical uses of this module are mapping of nodal data from a 3D mesh onto a geologic surface or a 2D fence section. In these applications the 2D surface(s) simply provide the new geometry (mesh) onto which the adjacent nodal values are interpolated. The primary requirement is that the nodal data be equal or higher dimensionality than the mesh to be interpolated onto. For instance, if the user has a 2D surface with nodal data (perhaps z values), then a 1D line may be input and the nearest nodal values from the 2D surface will be interpolated onto it.
Module Input Ports
Interp data has two input ports. The left input port will accept a 2D or 3D field (mesh AND nodal data) which contains the parameter to be interpolated. The right input port accepts a mesh of equal or higher dimensionality. Nodal values are not needed for data sent to the right input port, because the mesh from the right input port is used strictly to obtain coordinate locations where the left ports nodal data will be interpolated.
Module Output Ports
Interp data has two output ports. The left port outputs the data field with interpolated nodal data. This port can be connected to any module that can process data fields, such as the isolines module, which can use the data field to display isolines if the output were a surface. The right port outputs a renderable geometry of the surface that can be input to the viewer. This port can also be connected to the color legend module to set the limits of the displayed color scale.
Module Control Panel
The control panel for Interp data is shown in the figure above. The data component radio buttons are used to select which scalar data component is to be interpolated onto the surface or line of interest. The default selection is the first (0th) data component. Any number of check boxes may be chosen to pass downstream. The 0th data component is selected by default.
