Cylinder MK2

Functionality

This node generates primarily cylindrical shapes, but its settings allow to create a wide variety of tube like shapes.

Inputs

All inputs are vectorized and they will accept single or multiple values.

• Radius T - Top Radius

• Radius B - Bottom Radius

• Parallels - Number of Parallels

• Meridians - Number of meridians

• Height - The height of the cylinder

• Twist - Rotate parallel verts by this angle around Z from bottom to top

• Phase - Rotate all verts by this angle around Z axis

• Scale - scale the entire mesh (radii & height)

• Parallels Profile - parallels profile [1]

• Meridians Profile - meridians profile [1]

[1] : The profiles inputs do not take input values from the node, but can take multiple values form the outside nodes.

Parameters

The Separate, Cap T, Cap B, Center and the Angle Units can be given by the node only. The other parameters can take values either from the node or the external nodes.

Param	Type	Default	Description
Radius Top	Float	1.00	The radius of the top parallel.
Radius Bottom	Float	1.00	The radius of the bottom parallel.
Parallels	Int	2	The number of parallel lines. This is also the number of points in a meridian.
Meridians	Int	32	The number of meridian lines. This is also the number of points in a parallel.
Height	Float	2.00	The height of the cylinder.
Twist	Float	0.0	The amount of rotation around the z-axis of the parallel lines from the bottom to the top parallel.
Phase	Float	0.0	The amount of rotation around the z-axis of all the vertices in the mesh.
Parallels Profile	[Float]	[ ]	The scale modulating the radius of the parallels. [1]
Meridians Profile	[Float]	[ ]	The scale modulating the radius of the meridians. [1]
Caps T	Boolean	True	Generate the top cap or not.
Caps B	Boolean	True	Generate the bottom cap or not.
Separate	Boolean	False	Separate the parallels into separate lists. [2]
Center	Boolean	True	Center the cylinder around the origin.
Angle Units	Enum RAD DEG UNI	RAD	The Twist and Phase angles are interpreted as RAD : Radians [0.0, 2*pi] DEG : Degrees [0.0, 360.0] UNI : Unities [0.0, 1.0]

Notes:

• [1] : If connected the profiles need to have lists of at least 2 values.

• [2] : This splits the verts, edges, and polys into separate parallel sections.

Extended Parameters

The Property Panel provides additional parameters.

• Cyclic This parameter is used for treating the connected Parallels Profile as a cyclic spline curve and it is useful to ensure smooth parallel curves whenever there’s discontinuity in the value and/or in the tangent of the starting/ending points of the profile.

Outputs

Vertices, Edges and Polygons. All outputs will be generated when the output sockets are connected. Depending on the type of the inputs the node will generate only one or multiples independent cylinder shapes.

If Separate is True, the node will output the parallel sections as separate lists (verts, edges and polys).
