Extrude to Point

Functionality

This node generates a Surface by extruding some Curve (called “profile”) towards one point (also called “tip”). So the resulting surface is, generally speaking, a conical surface.

• Generator-> NGon

• Curves->Curve Primitives-> Fillet Polyline

• Surfaces-> Evaluate Surface

• Transform-> Randomize

• Viz-> Viewer Draw

Surface domain: along U direction - the same as of “profile” curve; along V direction - from 0 to 1. V = 0 corresponds to the initial position of profile curve; V = 1 corresponds to the tip point.

Inputs

This node has the following inputs:

• Profile. The profile curve. This input is mandatory.

• Point. The point towards the profile is to be extruded. The default value is (0, 0, 0) (origin).

Outputs

This node has the following output:

• Surface. The generated surface.

Examples of usage

Extrude a pentagonal polyline towards one point, to make a pyramid:

• Generator-> NGon

• Curves->Curve Primitives-> Polyline

• Surfaces-> Evaluate Surface

• Viz-> Viewer Draw

It is possible to use this node to fill planar (or semi-planar) curves with some grid:

• Generator-> NGon

• Curves-> Cubic Spline

• Surfaces-> Evaluate Surface

• Viz-> Viewer Draw
