vJSONRepeatTransform

Repeats an array in a line, circle, spiral or grid, with transforms spread across the copies.

AdvancedMograph / JSONJSONArrayScriptVal

vJSONRepeatTransform takes an array of XYZ points and outputs copies of it. Array Mode places the copies, and the Translate, Scale and Rotation controls change them from the first copy to the last. A second output holds the copy number of each point.

The copies are Number of Times in Linear, Circular and Spiral modes, and Grid Columns times Rows (times Depth for Grid 3D) in the grid modes. Circular puts copies on a circle of Radius in XY, Spiral adds a rise of Spiral Height over the copies, and the grid modes center a grid with the spacings. Translate, Scale and Rotation are totals reached at the last copy, with copy j getting the share j / (Number of Times - 1) of them.

Each copy is rotated around the Pivot in the Rotation Order, scaled by 1 + Scale * share, and moved. Random adds seeded offsets per copy, Shake adds smoothed noise over time, and Mirror negates every second copy. Position Array adds three numbers per copy. The Instance IDs output holds the copy number of each point, and ScriptVal Groups the points per copy.
