combine

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:
