Spline Bridge Mapper Grayscale

Input connectors

Spline Coords ColorThe 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 ColorAdditional 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 IntegerThe number of input splines.

Color MapGrayscaleThe input grayscale image that should be mapped across the input splines.

Output connectors

Color GrayscaleThe result of mapping the input Color image across the splines, as a grayscale image.

Height GrayscaleThe height of the splines mapped across the splines, as a grayscale image.

UV ColorThe UVs (I.e., coordinates) of the mapped image, encoded in the red (U) and green (V) channels of a color image.

Mask GrayscaleA mask of the mapping across the splines.

Parameters

Segments Amount IntegerSplines are simplified into segments before image coordinates traverse them.
A higher amount of segments results in a smoother mapping along curves.

Reduce UVs Stretching BooleanAdjusts the method used to interpolate the image coordinates from one spline to the next to minimize stretching when the distance between splines is uneven.

UV Scale Float2Adjusts the scale of the image coordinates. Higher values result in more a densely tiled image.

UV Rotation FloatRotates the image coordinates around their center.
