On its own, the main functionality of the Radial Tiling node is the ability to divide a 2D Cartesian coordinate system into as many radial segments as specified by the "Segments" input. Each segment has its own affinely transformed coordinate system, provided through the "Segment Coordinates" output, which can be used to tile textures in a radially symmetric manner. Additionally, a unique index is provided for every segment through the "Segment ID" output, the width of each segment at Y-coordinate of the "Segment Coordinates" output without normalization = 0 is provided through the "Segment Width" output and the rotation value of the affine transformation of the coordinate system of each segment is provided through the "Segment Rotation" output. The roundness of the coordinate lines of the "Segment Coordinates" output can be controlled through the "Roundness" inputs. This can be used to make the coordinate systems of the segments a mix of Cartesian and polar coordinates. Lastly, the lines of points of the "Segment Coordinates" output with constant Y-coordinates have the shape of polygon with rounded corners, which can be used to procedurally create rounded polygons.
