Combines SDFs in various ways.

Depending on which Combine option is selected, different parameters will be enabled. This operator only supports two input SDFs (along with a value field to control blending). To combine more than two SDFs, use one of the specialized operators like simpleUnion.

Parameters

  • Enable:
  • Combine: The type of combination operation to perform.
    • Simple Union: The combined areas of each of the inputs.
    • Simple Intersect: The overlapping areas of each of the inputs.
    • Simple Difference: The first input with the second input removed from it.
    • Smooth Union: Like `simpleUnion` but with the intersecting edges rounded out.
    • Smooth Intersect: Like `simpleIntersect` but with the intersecting edges rounded out.
    • Smooth Difference: Like `simpleDiff` but with the intersecting edges rounded out.
    • Round Union: Uses a quarter circle blending area along the edges.
    • Round Intersect:
    • Round Difference:
    • Chamfer Union: Uses a 45 degree flat slope to blend along the edges.
    • Chamfer Intersect:
    • Chamfer Difference:
    • Stair Union: Uses vertical and horizontal stairs to blend along the edges.
    • Stair Intersect:
    • Stair Difference:
    • Column Union: Uses multiple circular tubes to blend along the edges.
    • Column Intersect:
    • Column Difference:
  • Swap Inputs: Swaps the order of the inputs. This is only relevant for "diff" modes.
  • Radius: The size of the blending region.
  • Number: For stair and column modes, this controls how many steps are used in the blending regions.
  • Offset:
