Description

Draws a cross-sectional profile of an input. Can be adjusted to slice vertical or horizontal, and has controls for drawing style and graph offset and scaling.

This node is especially useful for debugging and analyzing heightmaps. giving you a pixel-perfect profile view, without needing complex nodes or a lengthy, less precise setup in the 3D View. Alternatively it can be used to create 2D shapes and silhouettes that are hard to achieve otherwise. Combined with a Curve node it can directly visualize the curve profile applied to a linear gradient.

Parameters

  • Cross section coordinate:  0.0 - 1.0
    Set at what coordinate to sample the slice. Can be X or Y coordinate depending on Section Axis.
  • Section axis:  X, Y
    Set if the slice is vertical or horizontal.
  • Height scale:  0.0 - 1.0
    Scales entire graph down. Useful for HDR viewing.
  • Height offset:  -1.0 - 1.0
    Shifts entire graph up or down. Useful for HDR viewing.
  • Drawing style:  Solid, Gradient, Gradient mirrored, Line
    Switch between solid fill and line drawing.
  • Invert Gradient: True - False
    If Drawing Style is set to Gradient or Gradient mirrored, lets you invert that gradient without affecting the background.
  • Smooth / Polygonal:  Smooth/Polygonal
    Switches shape between perfect smooth profile, or jagged, polygonal.
    Not available with Line drawing style. 
  • Segment amount:  2 - 256
    Sets the amount of segments used to draw when in Polygonal Style, or in Line Style.
  • Line thickness:  0.0 - 0.1
    If line drawing is enabled, sets thickness of the line.
  • Line style:  Smooth, Solid, Segment ID, Gradient along line
    If line Style is enabled, lets you choose coloring and falloff of the line.
  • Line smoothness:  0.0 - 1.0
    Sets gradient falloff of the line, only when Smooth Line Style is active.
  • Color:  (Grayscale value)
    Grayscale color of the line or shape.
  • Background color:  (Grayscale value)
    Grayscale color of the background.
