Wrangle Node Example - Dice Illusion

Inspired from the Straight Dice example on http://brainden.com/line-illusions.htm

I implemented this in Houdini. Overall it was a collection of grid nodes, color, point wrangles and delete nodes.

The technique used is as follows:

• small grids are copied onto a source grid of points
• modulus toggle between the color selections
• then a delete node using a bounding volume cuts out the center source points
• further delete using selected and non-selected for the special cases and finally point wrangles to rotate the grid elements correctly

The overall network appears below:

Since we are in Houdini, we can also experiment with copy:
