RayTK

v0.42

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

Name	Description	Regular Handling	Read-Only Handling
Enable
Combine	The type of combination operation to perform.	Runtime	Baked
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: Simple XOR:
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.
