|
|
tubularSegments — [page:Integer] - The number of segments that make up the tube. Default is `64`.<br />
|
||
|
|
radius — [page:Float] - The radius of the tube. Default is `1`.<br />
|
||
|
|
radialSegments — [page:Integer] - The number of segments that make up the cross-section. Default is `8`.<br />
|
||
|
|
closed — [page:Boolean] Is the tube open or closed. Default is `false`.<br />
