Target Faculty: Computer Vision, Industrial Design, CAD / 3D Printing & Digital Arts
ERIC Statutory Topic Alignment: Science, Mathematics, and Environmental Education; Information and Technology
Primary Dataset: DS-3 (limewire-generative-ai-models-benchmark-2026.csv) · Monograph: LimeWire-Vol5, Vol6 & Vol7

1. Theoretical Core

Comparative architecture of latent and pixel text-to-image diffusion models (Stable Diffusion 1.5 vs SDXL vs DALL-E 2 vs DALL-E 3 vs Google Imagen vs BlueWillow). Single-image 3D point-cloud and triplane mesh reconstruction via Point-Aware 3D (SPAR3D). Cubic Bezier spline vectorization into SVG, EPS, and CAD DXF, plus 4x neural super-resolution upscaling and outpainting.

2. Zero-Install Browser Laboratory Assignment (Lab Manual #4: Cross-Model Diffusion Benchmarking, 4x Super-Resolution, DXF Vectorization & SPAR3D Mesh Synthesis)

  1. Execute a standardized isometric industrial prompt across 5 models in browser: https://limewire.com/tools/stable-diffusion, https://limewire.com/tools/stable-diffusion-sdxl, https://limewire.com/tools/dall-e-3, https://limewire.com/tools/google-imagen, and https://limewire.com/tools/bluewillow-ai.
  2. Remove the background via https://limewire.com/tools/remove-background, upscale 4x via https://limewire.com/tools/ai-image-upscaler, and trace contours to SVG/DXF via https://limewire.com/tools/vectorize-image.
  3. Reconstruct a watertight 3D GLB mesh from the 2D orthographic render using https://limewire.com/tools/image-to-3d-model (SPAR3D) and test canvas extension via https://limewire.com/tools/outpaint-image-ai.

3. Required Browser Tools (Zero Local Setup / Chromebook Compatible)

4. Verified Instructor Answer Key

Q1 Answer: In DS-3, DALL-E 3 achieves 95.4% prompt adherence and 91.8% OCR typography accuracy due to dense synthetic recaptioning, while Google Imagen achieves 93.8% adherence at 4.95s latency. Q2 Answer: SPAR3D generates a ~42,500-vertex manifold mesh in ~6.2s by conditioning a triplane transformer on an explicit point-cloud diffusion stage.
