VS3D Region Mode

1.4.2 Region Application continued.

"Sculpt" continued :

• "Translate..." : This function will move the surface heights within the current region by a specified distance and direction. The "Apply Region Translate" dialog has four settings. The "Distance Measurement" setting is used to specify the coordinate system - Grid Units or Data Units. The "Translate Distance" specifies the XY distance (and direction) to move the surface. The "Backfill Mode" along with the "Backfill Plateau Value" specify what Z height (if any) to use to fill the vacated areas of the sculpture surface. It is possible for translated surface elements to end up outside the region.
  
• "Scale..." : This function will scale the surface (in the XY plane) within the current region by a specified factor. The "Apply Region Scale" dialog has five settings. The "Center Point Placement" setting is used to specify the coordinate system - Grid Units or Data Units. The "Scale Center" specifies the XY point to use for the scale center. The "Scale Factor" setting determines the scaling. This value should be greater than 0. Values less than 1 will shrink the XY dimensions of the surface. A value greater than 1 will expand the XY dimensions of the surface. The "Backfill Mode" along with the "Backfill Plateau Value" specify what Z height (if any) to use to fill the vacated areas of the sculpture surface (if any). It is possible for scaled surface elements to end up outside the region.
  
• "Rotate..." : This function will rotate the surface heights within the current region by a specified angle. The "Apply Region Rotate" dialog has five settings. The "Pivot Point Placement" setting is used to specify the coordinate system - Grid Units or Data Units. The "Pivot Center" specifies the XY point to use for the rotation center. The "Rotation Degrees" setting determines the rotation angle (degrees counter-clockwise). The "Backfill Mode" along with the "Backfill Plateau Value" specify what Z height (if any) to use to fill the vacated areas of the sculpture surface (if any). It is possible for rotated surface elements to end up outside the region.

"=" (equals) : The selected region operation will set the surface heights equal to the region "Z" height setting.

"+--" (plus-minus) : The selected region operation will add (or subtract) the region "Z" height to the surface.

"*" (multiply) : The existing surface heights within the region are multiplied by the region "Z" height.

"<" (less than) : The area within the region is set to the lesser of the existing surface heights and the region "Z" height.

"Z" : This field specifies the region Z height to use when applying a region.
