VS3D File Menu

1.1.5 Region - Load/Save/Import/Export.

"File / Region => Load Region (.vs3)..." : This will load a ".vs3" relief sculpture surface as the current region. After selecting a file, the "Import Region" dialog will appear. This dialog has one setting.

• "Region Load Mode" : "Load" - replace existing region with region data from file. "Merge" - the resulting region (at each sculpture grid point) is the greater of: the existing region, and the imported region.

The location where the loaded/merged region is placed depends upon the current Data Coordinate scales, and the Data Coordinate scales from the loaded/imported file. The current region is shown as red outlines in the sculpture grid window.

The current region is a mask, the same size as the sculpture grid, which specifies which sculpture grid points are inside the region and which are outside. The region mask contains values ranging between 0 (outside) and 1 (fully inside). It is possible for a sculpture grid point to be partially inside the region (a corresponding region mask value of greater than 0 but less than 1). When a region is loaded or merged, all incoming region mask values less than 0 are set to 0, and all incoming region mask values greater than 1 are set to 1.

"File / Region => Save Region (.vs3)..." : This will save the current region mask values to a ".vs3" file. The saved values will range from 0 to 1.

"File / Region => Import => VS3D Raw ASCII (.vsa)..." : This will load a ".vsa" file as a region mask. After selecting a file, the "Import Region" dialog will appear. This dialog is exactly the same as that for the "File / Region => Load Region (.vs3)..." menu.

"File / Region => Export => VS3D Raw ASCII (.vsa)..." : This will save the region mask values as a ".vsa" file. The saved values will range from 0 to 1.
