Overview

A home builder had 25 models and a folder of PDFs. I built a pipeline that turns each PDF into an accurate 3D model, then into every photo the website needs: four seasons, night, every side, every colour option.

The 3D models and render passes are built in Blender. The final photoreal images are AI-assisted: Magnific turns the Blender frame into a photo, and every output is checked against the Blender frame.

Drawing, model, photo

Lotus 1, front, summer, photoreal render

Move between drawing, model and photo

Same camera. The model is built from the drawing. The photo is built from the model.

Every opening checked against the drawing.

The model is overlaid on all four elevations and each window and door is ray-checked. A build goes to the client only at zero problems. Drawing in red, model in blue.

Lotus front elevation, drawing in red overlaid with the Blender model in blue — Front

Lotus left elevation, drawing in red overlaid with the Blender model in blue — Left

Lotus right elevation, drawing in red overlaid with the Blender model in blue — Right

Lotus rear elevation, drawing in red overlaid with the Blender model in blue — Rear

Openings checked, Cape Cod

Problems at every sign-off

Lotus main floor plan with the extracted wall outline in red — Wall outline on the plan

Lotus main floor plan with the checked openings marked — Openings on the plan

Seven steps, no hand modelling.

1 · PDF
The builder's PDF, read as vectors.
2 · Vectors + scale

One file holds walls, roofs, openings and cameras.

4 · Model
Headless Blender builds the model from the spec.
5 · Passes
4K beauty, depth, normal, line and material ID.
6 · Photoreal
AI photoreal pass (Magnific), checked against the Blender frame.

7 · Delivered images

One 1792 × 1008 JPG per image, versioned, into the website folder.

15 selected final images, five per model: Lotus (across its three colour options), Cape Cod and Daphne. Photoreal pass is AI-assisted from the Blender frame.
