GONDURAS MEAT MARKET (GMM): "The Multi-Model Assemblage" transforms 20 years of physical analog paper collage (and custom-trained SD 1.5 gondurastration style generations) by multidisciplinary artist Alexander "Gonduras" Jitomirsky into a verifiable, kinematic 3D OpenUSD and WebGL spatial theatre—engineered locally on a consumer 12GB RTX 3060 workstation. THE PROBLEM: Standard generative video diffusion and 3D reconstruction fail catastrophically on physical collage: 1. The 3.5-Second Video Collapse: Autoregressive video diffusion holds paper texture for ~2–3 seconds before sharp scissor cuts soften, halftone newsprint dissolves into airbrushed gradients, and 350gsm cotton rag cardstock melts into rubbery CGI plastic. 2. The Ceramic Smoothing & Pastel Washout Trap: Off-the-shelf 3D reconstruction and naive flat emission shaders turn paper fibers, totemic flat-sticker eyes, and cut seams into glossy porcelain figurines. OUR SOLUTION (V7 MULTI-MODEL ASSEMBLAGE): Instead of faking collage with video diffusion, we treat AI models as specialized computational craftsmen reading the artist's layered PSDs from distinct perspectives to construct both a live interactive WebGL stage (COLLAGE_STAGE_WORKBENCH.html — 1.32M vertices, 2.42M triangles, 0 JS errors) and a 480-frame (20s @ 24fps) Blender EEVEE OpenUSD hero film (frankenstein_assemblage_stage_v7.usda): 1. True-Color Scan Preservation (Delta-E < 5): Original GLB scan textures drive self-emission (skins 0.35, grafts 0.25) under Standard color management, keeping the fish's vintage silver-grey paper eye and orange bird's flat sticker eye intact with zero glassy 3D eyeballs. 2. V7 Contour & Silhouette Precision: Opaque volumetric backing cores (SAM-3D + Meshy + Kaolin) are tucked to 0.90 scale with family-frame trim masks and pre-export WEIGHTED_NORMAL edge smoothing—eliminating cut-glass facet seams on reflected contours while keeping the front razor-cut silhouette untouched. 3. 21 Internal Copper & Cyan Spars (Z < -0.005m): Removing surface wireframe cages ("no waffle"), 21 structural spars (#f4a261 for birds/fish, #4cc9f0 for cliffs) sit strictly behind the opaque paper skin—invisible at 0° frontal lock, revealed at 32°–35° oblique orbit. 4. 3-Act Theatrical Kinematics & Light Ramp: Exact matrix-inverse clamping (attachment.js, error < 3.7e-16m) seats the wriggling fish tail (+/-0.12 rad) inside the orange bird's beak while flock mutual gaze (+/-0.10 rad), 5 staggered emission blinks, and a keyed sun/fill light ramp breathe across the stage.
