SKetch To Tectonic Transalation



Overview: This research focuses on the "Human-in-the-Loop" workflow—using MLSD ControlNet to extract structural line segments from loose hand-sketches and translating them into high-fidelity architectural visualizations.








01. Conceptual Massing & Analog Realism

  • The Control: ControlNet: MLSD (Line Segment Detection). I used MLSD to isolate the structural edges of the initial concept sketch, ensuring the architectural perspective and vanishing points were locked before the rendering pass.
  • The Prompt: Analog film, Modern architecture, Wild1 LoRA. The objective was to blend the spontaneity of a raw sketch with a "found footage" aesthetic, exploring the "lived-in" quality of a home concept.
  • The Result: 35mm Grainy Film Effect. By using a 0.51 Denoising Strength, I achieved a balance between the hand-drawn spirit and a cinematic, vintage photographic finish that highlights texture and RTX lighting.

02. Nocturnal Facade & Lighting Simulation

  • The Control: ControlNet: MLSD. This allows for precise control over the building's facade lines, which is critical when testing how light washes over curved geometries and tree-lined landscapes.
  • The Prompt: Night view, Warm lighting design, GreenCondominium LoRA. This experiment focuses on Nocturnal Storytelling—simulating the interplay between artificial interior warmth and the natural textures of a summer night.
  • The Result: HD Night Photography. Through subtle 0.35 Denoising, the workflow preserves the original sketch's intent while injecting realistic light-bloom and star-lit environmental depth.

03. Volumetric Stacking & Professional Octane Render

  • The Control: ControlNet: MLSD. Strict line enforcement ensures that complex "stacked volumes" maintain their crisp edges and 3D modeling precision during the digital synthesis.
  • The Prompt: Octane render, Stacked_volumes LoRA, Volumetric lighting. The goal was to shift from "sketch" to a "Professional 3D Model" aesthetic, emphasizing structural depth and dramatic shadows.
  • The Result: Dramatic Volumetric Lighting. A hyper-realistic model finish with high-detail textures and Octane-style rendering, ideal for communicating form and site-specific topography in a client-ready format.
