v0.36

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

• Enable:
• Axis: The axis facing the plane along which space is repeated.
  • 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.
• Offset: Shifts where the input cell is taken from without moving the position of the grid.
• Shift: Shifts the whole grid (and its contents).
• Mirror Type: How the cells are varied.
  • 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.
  • 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:
  • None:
  • Both:
  • Start Only:
  • Stop Only:
