proof1-render.mjs — PROOF 1: the lit chamber, split into planes.
|
||
Takes the locked golden merge composition (REFINED_Backlit7,
|
||
the mirror event, uniform-lace merge) and emits it as SEPARATE
|
||
transparent planes for a backlit acrylic stack, plus a manifest
|
||
and a parallax/backlight simulator to art-direct the depth
|
||
BEFORE committing to print.
|
||
|
||
Plane map (deepest → nearest), causal depth cause→world→evidence:
|
||
1 sun faded disk · pure transmitted colour · zero white
|
||
2 sea-far sheet[0]
|
||
3 sea-mid sheet[1]
|
||
4 sea-near sheet[2]
|
||
5 event-halo merged bubbles, blurred by the air gap (glow)
|
||
6 event-core merged bubbles, sharp · white underlay
|
||
+ front-glass grain + aging (the surface, multiply)
|
||
|
||
Golden frame (φ) is preserved and FLOATED in an A3 sheet later;
|
||
this stage renders the art square only.
|
||
|
||
Usage: node tools/proof1-render.mjs [width]
