VS3D Region Mode
1.4.1 Region Definition/Modification continued.
"Modify" : This pull-down menu contains functions for modifying the current region. These operations modify the region only - they only affect the sculpture surface if the modified region is subsequently used in sculpting the surface.
- "Swap in/out" : This function will turn the region inside-out. The resulting region will enclose everything that was outside the region before the swap.
- "Smooth..." : The "Smooth Region" dialog has one setting for the smooth window width. The larger the number, the greater the degree of smoothing. This function, in effect, imparts a permanent "feathering" to the region.
- "Crosshatch..." : The "Crosshatch Region" dialog is used to apply a series of parallel drop-out lines across a region. The Crosshatch settings include the drop-out line width and line spacing (both in grid coordinates), the dropout height (a factor from 0 to 1), and the crosshatch angle (in degrees counter-clockwise from horizontal).
- "Random Texture..." : The "Random Texture Region" dialog is used to apply a quantity of randomly-located drop-out points across a region. The texture settings include the drop-out density (from 0 to 100%) and the dropout height (a factor from 0 to 1). A drop-out density of 100% will not result in all points of the region dropping out because many random points can map to the same region point.
- "Expand..." : The "Expand Region" dialog has one setting for the "Expand Width". The larger the number, the greater the degree of expansion. This function, in effect, will grow ("dilate") the region.
- "Contract..." : The "Contract Region" dialog has one setting for the "Contract Width". The larger the number, the greater the degree of contraction. This function, in effect, will shrink ("erode") the region.
- "Perimeter..." : The "Region Perimeter" dialog has one setting for the "Perimeter Width". The larger the number, the wider the perimeter. This function, in effect, hollows out the region, leaving only it's perimeter.
- "Spine" : This will collapse the region shape down to it's spine. Similar to "Skeleton", but with fewer branches.
- "Skeleton" : This will collapse the region shape down to it's skeleton with all branches connected.
- "Linear Replicate..." : The "Region Linear Replicate" dialog has settings for the coordinate system, XY "Replicate Direction Vector", and the number of copies. Use this function to duplicate the current region multiple times in a straight path.
- "Angular Replicate..." : The "Region Angular Replicate" dialog has settings for the coordinate system, XY "Pivot Center" point, the Replication Angle (degrees counter-clockwise), and the number of copies. Use this function to duplicate the current region multiple times along an arc.
- "Flip Vertical" : This function will flip the current region top-to-bottom.
- "Flip Horizontal" : This function will mirror the current region side-to-side.
- "Scale..." : The "Scale Region" dialog has settings for the coordinate system, XY "Scale Center" point, and the "Scale Factor". The scale factor should be set greater than 0. A value less than 1 will reduce the region size. A value greater than 1 will increase the region size.
- "Rotate..." : The "Rotate Region" dialog has settings for the coordinate system, XY "Pivot Point", and the rotation angle (degrees counter-clockwise).
"Show | Hide" : This setting controls the visibility of the region perimeter (red outlines). It is often useful to hide the region momentarily (without deleting it) to view the sculpture surface without the region outlines. For most operations, the region is inactive when hidden.
