Method

This node extrudes n-gon shapes along a spline. The spline used to generate the shape must be connected via the Spline Sources input.

Attributes

Name Description
Visible Control whether the node is visible or not to the scene.
Seen By Rays Enable the mesh to be seen by the raytracer.
Radius The radius of the shape to be extruded along the spline.
Num Radial Segments How many sides the extruded shape will have.
Num Spline Segments How many sections the extruded shape is broken up into when following the spline.
Use Spline Colours use the colours from the input sspline to
Max Visible Age The maximum length the extruded geometry can get to as a function of age. Only functions with a Node Trail input.
Fade Front Duration How long the front edge fades for as a percentage of the whole spline.
Fade Back Duration How long the back edge fades for as a percentage of the whole spline.
Fade Alpha Fade the alpha values of the generates spline along its length using Fade Front and Back Duration. Requires an alpha supporting blend mode.
Fade Scale Scale the radial size of the spline using the Fade Front and Back Duration.
Draw Triangles Toggle whether the mesh faces are drawn.

Lines

Name Description
Lines Visible Control whether the node is visible or not to the scene.
Lines Alpha Control the alpha value of the lines.
Colour Control the colour value of the lines.
Use Vertex Colours Colour lines based on the vertex colours of the geometry.
Blend Mode Control how the lines blend with the rest of the scene.
Thick Lines Use lines with thickness relative to their distance to the camera.
Hide Back Face Lines Hides the lines around back faces of geometry.
Lock Width Lock the line width to be consistent regardless of distance from the camera. Only functions with Thick Lines enabled.
Thick Line Width Control the thickness of all the lines. Only functions with Thick Lines enabled.
Show Silhouette Lines Draws lines along the edges of the object relative to the camera.
Show Normal Difference Lines Draw a line along the edges of the mesh, depending on the angle difference between their mutual faces.
Show Unshared Lines Draw lines along all edges of the shape.
Show Other Lines Show all the lines for each edge of the Mesh.
Unshared Lines Weight Greater control over the alpha of the unshared lines.
Silhouette Lines Weight Greater control over the alpha of the silhouette lines.
Normal Difference Lines Weight Greater control over the alpha of the normal difference lines.
Other Lines Weight Greater control over the alpha of the other lines.
Line Normal Difference Angle Change the threshold angle between two face normals that will generate a line along their common edge. Only functions with Show Normal Lines enabled.
Line Normal Fade Sharpness How much the drawn normal lines will fade away the closer the edge angle is to the Line Normal Difference Angle.
Line Depth Bias Exaggerate the width of the lines based on the distance to the camera. not functional with Lock Width enabled.
Line Silhouette Fade Sharpness How much the drawn silhouette lines will fade away based on the size of the edge angle to the camera.

Inputs

Name Description Typical Node Input
Spline Sources Spline nodes used to draw the extrusion along. Spline
Material Override the default material with another material. Materials
Transform Modifier Links all transform properties to the input node. Null
Target Node Always faces the x-axis towards the inputs anchor point. Null
Local Transform Override Override the transformation values of the node, relative to its parent. Null

Outputs

This node outputs the normal transformation and translation values, but it also outputs geometry which can be Deformed or used as a mesh source by other nodes.
