Pixel Cut

The “Pixel Cut” pushes the Cross-Bar geometry into a more modern, high-contrast profile. It leans on the optimizer to chase contrast intensity while keeping the pavilion layout compact. Start from the pavilion mains, build a simple girdle reference, then let the meetpoint ladder walk with evenly spaced projections to sculpt the interior reflections.

For the crown, this variation adds a pair of edge-plane helpers that feed a stepped trio of facets (“pixels”) radiating inwards. Arrays keep the optimized angles organized, so you can dial in each band without hunting through the whole code block. Drop the snippet into the studio, tweak the [value] entries, and re-run the optimizer any time you want to re-balance brightness versus contrast.

In the design below, all angles can be adjusted (manually or by the optimizer), while keeping the same pixel layout. Magic.
