Bezier Curve Out¶
Functionality¶
This node generates Blender Curve objects of Bezier type. Blender’s curve bevelling feature is supported as well.
This node can be used to bring Sverchok’s Bezier, NURBS or NURBS-lie curves into Blender scene.
Note that Blender’s Bezier curves can have only one possible degree of 3. However, Sverchok can automatically elevate degree of the curve, so this node can also take curves of degree 1 or 2 as input.
Inputs¶
This node has the following inputs:
Curve. Sverchok’s Curve object to be generated as Blender object. This input is available and mandatory only if Input mode parameter is set to Bezier curve or BSpline curve.
ControlPoints. Control points of curve to be generated. This input is available and mandatory only when Input mode parameter is set to Curve control points or Segment control points.
Matrix. Transformation matrix to be applied to the generated object. By default, identity matrix is used (no transformation).
Radius. Bevel radius. The node can process either single value per curve, or a specific value per Bezier control point. Default value is 0.0.
Tilt. Tilt value. The node can process either single value per curve, or a specific value per Bezier control point. Default value is 0.0.
BevelObject. Blender’s Curve object to be used as Bevel object. If not specified and Bevel Depth is not zero, then round profile will be used.
TaperObject. Blender’s Curve object to be used as Taper object. This input is optional.
Parameters¶
This node has the following parameters:
Live - Processing only happens if update is ticked
Hide View - Hides current meshes from view
Hide Select - Disables the ability to select these meshes
Hide Render - Disables the renderability of these meshes
Base Name - Base name for Objects and Meshes made by this node
Select - Select every object in 3dview that was created by this Node
Material Select - Assign materials to Objects made by this node
Add material - It creates new material and assigns to generated objects
Bevel depth - Changes the size of the bevel. To disable bevelling, you have to set this to 0 and unset BevelObject input / parameter.
Input mode. This defines how input curves are provided. The available options are:
Segment control points. In the ControlPoints input, the node will expect a list of lists, each of which consists of exactly 4 control points for each Bezier segment.
Curve control points. In the ControlPoints input, the node will expect a single list of all (concatenated) Bezier segments.
Bezier curve. In the Curve input, the node will expect a Sverchok’s Bezier Curve object. Such an object can be generated, for example, by Bezier Spline node.
BSpline curve. In the Curve input, the node will expect Sverchok’s BSpline curve, i.e. non-rational NURBS curve or NURBS-like curve.
The default option is BSpline curve.
Outputs¶
This node has the following output:
Objects. Generated Blender’s Curve objects.
