// COPPER REEF — rasterbars reborn as 3D lacquered slabs: a stack of
|
|
// full-width copper bars sine-dancing and weaving in depth. Pattern
|
|
// taught: the choreography CROSSFADE — `mode` (sine) rolls into
|
|
// `mode_b` (curtain) and back on every bar via `p3: "0.5-0.5*cos(bar*
|
|
// tau)"` (curtain keeps each bar's side of the centre, so the morph
|
|
// never collapses the stack); `p0` pumps the dance amplitude with the
|
|
// bass and `p1` is the classic rasterbar thickness breath.
