Description

Merges all splines in the input list into a single spline.


Input connectors

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 merged splines as a grayscale image.

Spline Coords Color
The coordinates of the merged 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 merged 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 merged splines.


Parameters

Closed Spline Distance Threshold Float
The distance in texture space below which two extremities of a same spline are processed as a single point closing that spline.
This prevents overlaps when scattering shapes or mapping images along the splines.
