cue.spotlight

Takes the rest of the environment down — the other marks, the grid and the axes — and leaves what it wraps lit. Purely the dimming: nothing is drawn on the content itself, so pair it with a cue.highlight where a ring is wanted too.

cue.spotlightNode
Three frames of a spotlight: three curves at full strength, then the grid, the axes and two of the curves dimming, then only the teal curve lit.Three frames of a spotlight: three curves at full strength, then the grid, the axes and two of the curves dimming, then only the teal curve lit.
