[lane A] MODELBEAST dresses the molecules: 5 matcaps, and the canal picks space-filling
The right axis wasn't "generate or don't" — it was WHICH HALF. Geometry stays procedural because a molecule's shape is already known exactly. **Material is exactly a generation problem**, and it's the whole difference between a textbook diagram and a game object. So MODELBEAST made the materials. 5 greyscale matcaps, flux_local, 69 seconds, $0.00, 68 KB total: mol_glass (O,N) — the big win: oxygen is a red glass marble with internal glow mol_matte (C) — graphite soot; carbon reads as the scaffold it is mol_chrome (Co) — B12's cobalt is now a chrome bearing in a cage mol_molten (P) — ATP's phosphate tail is incandescent AND pulses (uTime, free) mol_pearl (H) — satin white; hydrogens stop shouting The trick is Lane D's own law applied to spheres: author the LUMINANCE, tint in-shader. derive_maps already greyscales every matcap, so one glass ball serves oxygen AND nitrogen at their own CPK hues — 5 balls dress the whole periodic table we care about. They pack into one strip atlas indexed per-vertex by aMat, so **a molecule is still exactly 1 draw call** however many materials it's made of (7 molecules = 7 draws, unchanged). ?matcap=0 falls back to the built-in fake-lit path: the assets-optional law holds. SPACE-FILLING WINS FOR PICKUPS, and the canal decided it, not me. New `repr: 'space-filling'` draws every atom at its real van der Waals radius with no sticks. A/B'd at real pickup size against the real L2 wall, same camera: ball-and-stick goes spindly and dissolves; the solid blob holds its silhouette — and it's CHEAPER (21k vs 26k tris, no bond cylinders). Recommendation to B: space-filling in flight, ball-stick for hero/UI/collect close-ups where the chemistry is worth reading. Evidence: round2_molecule_materials.png (3-way). Two defects found by rendering it, both mine, both fixed: - Tint x luminance darkens TWICE: CPK carbon is 0.4 and a matte ball averages 0.5, so soot x soot vanished — the first pass sank glucose, caffeine and the cobalt into the background. Floored the matcap at 0.22, the same floor the fallback's key light always had. - The molten matcap was my own bad prompt: I asked for an "incandescent white hot CORE" and got exactly that — a black ball with a hot spot, so phosphorus lost its orange. Re-rolled for the whole sphere to glow (attempt 2 of the <=2 PIPELINE allows). Lesson for the kit, next to the organ/tissue one: a matcap is a LUMINANCE LOOKUP, so a dark-dominant ball makes a dark-dominant object. Also corrected the doc's own framing — v1 said "I'm authorised to burn GPU and I'm not going to", which was the wrong axis, not just the wrong tone. qa GREEN; 16/16 texture provenance verified (synced the FIXED batch json up first this time, so the box couldn't clobber it on the way back).

[lane A] Molecules as pickups: real gut chemistry, procedural, 1 draw each
PROTOTYPE + proposal, not wired into boot. Pickups are B's systems, their economy is C's, object art is D's — this is a renderer and an argument, offered to all three. Bench: web/dev/laneA_molecules.html · docs/MOLECULES.md THE PITCH: the pickups already in L2 ARE molecules. C authored `nutrient`, `mucin`, `B12` and `antacid ammo` before any of this existed — those are the real biochemistry of a digestive tract, and glucose/cobalamin/bicarbonate are real compounds with known shapes. We don't need to invent a pickup language; we need to stop hiding the one the fiction handed us. GUTS is already a science game (an eosinophil is a real white blood cell, candida a real yeast, the hiatus a real choke point) — it just doesn't LOOK like one, because everything on screen is tinted tissue. THE RULE THAT MAKES IT WORK: CPK is the scanner. Everything identified is drawn in the standard element palette (O red, N blue, P orange, metals pink); everything else stays monochrome tissue. Against six biomes of tinted wall a CPK molecule is the ONLY saturated foreign colour on screen — it reads as artificial, valuable and targetable with NO HUD marker. Proof: round2_molecules_in_canal.png. That's the ART_BIBLE's synthetic-scanner fiction paying rent, and it hands Lane E a free HUD palette. WHY PROCEDURAL AND NOT MODELBEAST — and I'm authorised to burn the GPU: a molecule's shape is already known exactly. Glucose is a hexagonal ring because it IS one. FLUX+TRELLIS gives a plausible blob in 3-8 min that a chemist clocks as wrong and that can never be re-derived. Ball-and-stick from an atom list is exact, rebuilds in ms, and is ONE DRAW CALL per molecule (measured: 7 molecules = 7 draws / 26.5k tris). The split is a principle: small molecules = procedural (exact geometry known); proteins/enzymes = MODELBEAST blobs (real ones are 3000-atom blobs nobody reads — and PIPELINE says blobby organics are TRELLIS's sweet spot); cells/creatures = MODELBEAST, D's lane, unaffected. BUILT: water (chaff) · bicarbonate (antacid ammo — HCO3- + HCl is the real neutralisation, it genuinely fizzes CO2) · glucose (nutrient/score) · caffeine (overdrive — really gut-absorbed, needs no tutorial) · ATP (boost — the orange triphosphate tail IS the charge, a pickup that's a diagram of its own mechanic) · capsaicin (burn hazard — long greasy tail reads wrong on sight) · B12 (rare treasure — a cobalt in a corrin cage, the only metal vitamin; C authored it as a pickup already). Size is a free rarity signal: `unit` mode keeps TRUE relative sizes, so water is a speck and B12 a chandelier. Found by rendering it, which is why the bench exists: fuseRing returns vertices starting adjacent to B, and bonding them from A instead draws a chord across the ring — still a valid 5-cycle so nothing errors, it just looked like a squashed pentagon. Fixed in caffeine + ATP's adenine, adjacency documented. Stated plainly: geometry is idealised (correct connectivity/rings/bond orders, believable angles, authored flat) NOT crystallographic — real glucose is a chair, not a hexagon. The B12 is a simplified corrin core. Untested above ~7 on screen; fifty would want instancing. qa GREEN. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |
