Sweep

generators/sweep·v1.5.1

IN:2 OUT:1

SUMMARY

The Sweep copies a cross-section along every input curve and skins it into polygons: a round tube, a square tube with optional rounded corners, or your own profile from the second input. With Reorient Curve on, the built-in Orient Curve gives each curve a twist-free frame with a seed orientation and optional twist by ramp, TOP or attribute.

Width and scale can vary along the curve by ramp, TOP or attribute, and color by ramp or TOP. Skin options connect rings per curve or across curves, open or closed, as quads or triangles, with vertex normals and attributes transferred from the backbone curves and cross-sections.

PARAMETERS

PAGEOrient Curve

Reorient Curve	Reorientcurve	Reorient the curve frames before use.
[+]Seed Orientation	Seedorient	Determines the frame at each curve start: Curvature or Up Vector.
[+]Up Vector	Upvector	Sets the up direction when Seed Orientation is Up Vector.
Twist Amount	Twistamount	Twist along the curve, scaled by the twist ramp. Angles are given in degrees.
Open Twist Ramp Editor	Opentwistrampeditor	Open the editor of the twist ramp.
Reset Twist Ramp	Resettwistramp	Resets the twist ramp.
Custom Twist TOP	Customtwisttop	Reference to a TOP used as the twist ramp, overriding the ramp editor.
Twist by Attribute	Twistbyattr	Scale the twist by a point attribute instead of the ramp.
Twist Attribute	Twistattr	Sets the point attribute that scales the twist.

PAGESurface

[+]Surface Shape	Surfaceshape	Determines the cross section: the cross sections from the second input, a round tube or a square tube.
Width	Width	Sets the width of the swept surface. A LineWidth attribute overrides it.
Columns	Columns	Sets the number of sides of the round tube. Not used by the square or input cross sections.
Round Corners	Roundcorners	Enable round corners.
Corner Radius	Cornerradius	Sets the radius of the rounded corners.
Corner Sides	Cornersides	Sets the number of sides on round corners.
Scale Cross Sections	Scalecrosssections	Sets the scale of the input cross sections.
Unique Points	Uniquepoints	Enable not sharing points between primitives.
[+]Skin	Skinops	Determines how the cross sections are skinned: per line strip, all primitives, groups of N primitives, or skipping every Nth primitive.
N	Inc	N value when skinning groups of N input primitives or every N input primitives.
Closed Surface	Closedsurface	Enable connecting the last vertex to the first.
Output Quads	Outputquads	Whether to output quad primitives instead of triangle primitives.
Apply Scale Along Curve	Applyscale	Enable varying the scale along the curve.
Open Scale Ramp Editor	Openscalerampeditor	Open the scale ramp editor.
Reset Scale Ramp	Resetscaleramp	Resets the scale ramp.
Custom Scale TOP	Customscaletop	Reference to a TOP used as the scale ramp, overriding the ramp editor.
Scale by Attribute	Scalebyattr	Enable taking the scale from a point attribute instead of the ramp or TOP.
Scale Attribute	Scaleattr	Sets the point attribute used as the scale when scaling by attribute.
Apply Color Along Curve	Applycolor	Enable varying the color along the curve.
Open Color Ramp Editor	Opencolorrampeditor	Open the color ramp editor.
Reset Color Ramp	Resetcolorramp	Resets the color ramp.
Custom Color TOP	Customcolortop	Reference to a TOP used as the color ramp. It overrides the ramp editor.
Generate Vertex Normals	Generatevertexnormals	Generate vertex normals on the output.
Max Number of Primitives per Point	Maxprimsperpoint	Used to allocate temporary storage, it should be set to the maximum number of primitives a point can be a part of in the input geometry.
Angle	Anglenormal	For vertex normals, the threshold angle between faces above which the shared edge vertices don't share normals.

PAGEAttributes

From Backbone Curves	Frombackbonecurves	Sets the attributes transferred from the backbone curves.
[+]From Cross Sections	Fromcrosssections	Sets the attributes transferred from the cross sections.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
