The group of polygons to convert to wires.

This is the radius of the wire to sweep over the polygon.

A float point attribute that will be multiplied with the wire radius to set the radius of the wire.

Scale the intersection point of edges to avoid a collapse when sharp turns are made.

Prevent Joint Buckling scales up the intersection points so that they lie on the intersection of two tubes, rather than a width-sized sphere. This can cause the points to be scaled past the first segment of the tube, however, causing buckling. This parameter allows you to change on a point level what the maximum scale applied to the points is.

If the expression evaluates to a non-zero value for a point, the generated tube is smooth and connected through that point. If the expression is zero, the corresponding segment is disconnected. A value of zero will leave ends uncapped.

A float point attribute. If it is less than 0.5 for a point the point will be disconnected, as if the Smooth Point was set to zero.

Points with more than this number of edges connected to them will be treated as if the smooth point was set to zero. They will thus be disconnected. Such highly connected points will often produce bad results regardless, and more critically, require increasing time and memory to process that swiftly becomes prohibitive.

This is the number of divisions in the circle which is to be swept over the polygon. It can vary on a point basis.

An integer point attribute to override the number of divisions at each point. This will override the Divisions parameter.

The number of segments to divide each edge of the polygon into. It can vary on a point basis.

An integer point attribute to override the number of segments each edge of the polygon will be broken into. The segment will use the average of the values of the end points. This overrides the Segments parameter.

These are how far into the segment to make the first circle and how far towards the end to keep going. Both values are in the range 0-1, where 0 is the start and 1 the end. These are segment specific values. The local variable $NSEG is available here for the number of segments in the previous parameter.

If this is disabled, the values of 1/Segments and 1 - 1/Segments will be used.

Toggles whether vertex textures are generated for the geometry. For best texturing of branch points, the points of the wire should be ordered so the “important” side has least point number. For example, in a Y branch, the bottom of the Y should have the smallest point numbers.

A per segment parameter which cycles how far around the tube the seam is placed. The seam is always snapped to the nearest polygon edge.

Per segment values for the starting/ending values of the u texture.

Per segment values for the starting/ending values of the v textures.

A float point attribute providing the v-coordinate for each point. Segments will get this value for all the points generated at the intersection point.

The Edge Transport SOP can be used to compute the lengths of curves from an origin to compute v texture attribute.

If enabled, the up vector at each joint is set to the specified value. This will result in twisting of the branches.

A vector point attribute providing the up-direction for each point. This affects the twisting of the branches at this junction.
