RayTK

v0.42

Repeats space along 2 axes.

This has the effect of making an infinite grid of copies of (slices/cells of) the input, but without the cost of having to separately calculate each copy.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable
Axis	The axis facing the plane along which space is repeated.	Runtime	Semi-Baked
YZ: Repeat space on the Y and Z axes. ZX: Repeat space on the X and Z axes. XY: Repeat space on the X and Y axes.
Size	The spacing of the grid along the two axes. This sets the size of the cell taken from the input.	Runtime	Baked
Offset	Shifts where the input cell is taken from without moving the position of the grid.	Runtime	Baked
Shift	Shifts the whole grid (and its contents).	Runtime	Baked
Mirror Type	How the cells are varied.	Semi-Baked	Semi-Baked
None: All cells are treated the same. Mirror: Every other cell is flipped. Grid: Flip every other cell along the diagonal axis as well. This means that for an input with something in one corner, there will be groups of 4 cells with all those corners facing each other.
Iteration Type	Whether and how to expose iteration values to upstream operators.	Semi-Baked	Semi-Baked
None: Pass along whatever is provided by the next op after this one. Quadrant Index (0-3) In Tiles: For each cluster of 4 cells, output 0 for the top left, 1 for top right, 2 for bottom left, and 3 for bottom right, and put that value in the x component, and set yzw to 0. Cell Coordinates: Use the cell coordinates as the x and y components of the iteration, with zw set to 0. Note that it always uses xy, even if the grid is along another plane. Alternating Cell Coordinates On Axes (0-1, 0-1): Cell coordinates that alternate between 0 and 1 along both axes in xy, with zw set to 0.
Limit Type		Semi-Baked	Semi-Baked
None: Both: Start Only: Stop Only:
Limit Start
Limit Stop
Limit Offset
