The checkerboard node can be used to generate varoius geometric patterns. By default it generates a checkerboard
The pattern can be changed in size and color.
The Checkerboard can be used to generate a grid when the ‘line color” and “line width” are set.
The pattern is centered by default. To control the position of the lines you can add a G’MIC_ArrayRegular node with “X-Tiles”=1 and “Y-Tiles”=1. To make the pattern tileable you will have to change the Extent of the checkerborad to “Size” and choose a vulae that is a multiple of the “Box Size” parameter.
