### NVIZ - Mkdspf Panel

The Mkdspf panel provides facilities for creating display files (dspf) of isosurfaces from volume data (grid3 files).

### Mkdspf Panel

Input File: Enter name of grid3 file from which to create isosurfaces.

Output File: Name of display file produced. Should have .dspf extension.

Color File: Another grid3 file from which to find color values for isosurfaces.

Lighting Model: Choose one of flat or gradient . Flat shading is somewhat faster in computation and display, but gradient allows gouraud shading for isosurfaces with nicer display results.

Threshold type: Current must be one of Complete, Range, or Individual. Click on name of current selection to pop up list from which new threshold type can be selected. Panel changes depending on Threshold type selected.

Individual:Type in individual threshold values. List of selected values will appear in Iso Levels box. Use add and delete buttons to add or delete current value from list.

Complete: Type in Interval Size . Isosurfaces will be computed at Interval-size steps from minimum to maximum data values.

Range: Type in values for Min, Max and Num Levels and select one of the Interpolation toggles: linear logarithmic Quadratic Arbitrary. The number of levels specified will be computed within the range Min to Max, with interval computed according to Interpolation method chosen.
