<h2>Methods</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>THREE.TubeGeometry.FrenetFrames([page:Curve path], [page:Integer segments], [page:Boolean closed])</h3>
|
||
|
|
<div>
|
||
|
|
path — A path that inherits from the [page:Curve] base class <br />
|
||
|
|
segments — The number of segments that make up the tube <br />
|
||
|
|
closed — Is the tube open or closed
|
||
|
|
</div>
|
||
|
|
<div>
|
||
|
|
A static method that generates the Frenet Frames. This is internally run on any new TubeGeometry and then the
|
||
|
|
generated tangents, normals, and binormals are exposed as properties on the TubeGeometry object.
