One frosted pane as a die set, taken apart into the layers it is drawn from and stacked bottom up on four guide pillars that stand on the corners of the pane’s 360 × 220 box. At the bottom, the picture behind the pane. Above it, the frosted copy I make of it: it covers the box plus 100 px on every side, the reach of the bend and the blur (6 × 11.8 + 3 × 9 + 2), and I draw it at half size, 280 × 210. Then the distance field, just the size of the box, engraved here in rings 12 px apart. On top, the glass, 40 px thick, flat in the middle and curved only in its 34 px bezel, the one band where the picture bends, by 71 px at most. The result is copied into the pane’s 2D canvas, the small frame on the front ledge.

Drawn while the skill was being made, for a long article on rendering frosted panes in WebGL.
