Description

Generates splines traversing all splines in the input list, along these splines.

The generated splines can be Linear (straight) or Quadratic Bezier (curved).

Tip:

The generated splines go from the first spline in the list to the last and traverse the intermediary splines by strictly following the order of these splines in the list.

Therefore, you should be mindful about the order in which you append splines together beforehand.

Input connectors

Preview Grayscale
The preview of the input splines as a grayscale image.

Spline Coords Color
The coordinates of the input splines’ points encoded in the RGBA channels of a color image:
    R - X position
    G - Y position
    B - Height
    A - Packed data:
        - Sign: Spline is closed (negative) or open (positive);
        - Absolute value: Thickness + 1.

Spline Data Color
Additional data of the input splines encoded in the RGBA channels of a color image.
    R - Tangents X
    G - Tangents Y
    B - Unused
    A - Unused

Spline Amount Integer
The number of input splines.

Output connectors

Preview Grayscale
The preview of the output splines as a grayscale image.

Spline Coords Color
The coordinates of the output splines’ points encoded in the RGBA channels of a color image.
    R - X position
    G - Y position
    B - Height
    A - Packed data:
        - Sign: Spline is closed (negative) or open (positive);
        - Absolute value: Thickness + 1.

Spline Data Color
Additional data of the output splines encoded in the RGBA channels of a color image.
    R - Tangents X
    G - Tangents Y
    B - Unused
    A - Unused

Spline Amount Integer
The number of output splines.

Parameters

Bridge Spline Amount Integer
The number of splines generated across the input splines.

Bridge Splines Type Integer
The type of spline that is generated:
- Linear: a sharp spline connecting intermediary splines with straight trajectories from Start to End;
- Quadratic Bezier: a curved spline connecting intermediary splines with smooth trajectories from Start to End.
Note: At least 3 input splines are requires to compute a Quadratic Bezier spline.

Input Splines are Closed Boolean
Controls whether the first and last points of input splines should be processed as a single point. This prevent duplicating the first and last traversing splines.

Flip Direction Boolean
Inverts the direction of the spline.

Close Bridge Spline Boolean
Extends the traversing splines to connect back to the first spline in the input list.

Start Offset Float2
Applies an offset to the start of all traversed splines. The value is the normalized length of the input splines.
Generated splines that meet the start or end of the traversed splines are left there.

End Offset Float2
Applies an offset to the end of all traversed splines. The value is the normalized length of the input splines.
Generated splines that meet the start or end of the traversed splines are left there.

Uniform Distribution Boolean
When True, the points of the generated splines are evenly spaced from start to end.

Non-Square Correction Boolean
Adjust the points’ positions and thickness to retain the spline shape in non-square resolutions.
This also impacts uniform distribution.

Show Direction Helper Boolean
Displays a dot at the start of the spline and an arrowhead at its end in the Preview output.

Show Thickness Envelope Boolean
Displays additional lines at the edges of the spline’s thickness.

Segments Amount Integer
Adjusts the number of segments used to draw the spline visualization in the Preview output.
A higher value results in a smoother line.

Thickness (px) Float
Adjusts the thickness of the spline visualization in pixels in the Preview output.

Background Preview Intensity Float
The intensity of the Preview visualization.
