Cullinan: Immersive Sales Gallery

Spatial Digital Twin Projection Mapping, Motion Graphics & Panoramic Drone Compositing, Laser & Spatial Audio Integration

2024 / The International Commerce Centre, West Kowloon, Hong Kong

A CAD-derived spatial projection mapping system for a large-scale architectural installation, integrating panoramic drone filming, GIS topographical data, data-driven motion graphics, rendered Blender 3D environments, multi-channel spatial audio, and laser synchronization into a consolidated playback environment.

The production pipeline of "Cullinan: Immersive Sales Gallery" relies strictly on physical-to-virtual registration: baseline measurements were extracted directly from topographical data and architectural CAD blueprints before aligning virtual geometry in Blender. This structured 1:1 digital twin integration ensures assets meet the exact tolerances required for physical venue projection mapping.

The deployment replaces traditional static architectural models with a data-driven, spatially accurate visual showcase. Urban infrastructure, transit connectivity, and environmental metrics are procedurally generated and mapped directly onto fabricated surfaces, ensuring spatial precision and immediate viewer comprehension of complex geographical datasets.

Hardware Scoping & CAD-to-Virtual Registration

Projection surface geometry and physical venue constraints were scoped using Rhino 3D NURBS modeling in direct alignment with fabrication schematics. While scaled 3D-printed mockups were utilized strictly for early-stage proof-of-concept and client validation, the core engineering relied on CAD blueprints to plot projector lens ratios, throw distances, and optical overlap zones, resolving hardware conflicts prior to site installation.


Pre-Visualization & Drone Choreography

Custom aspect ratios of the curved physical screen were modeled in Blender to establish exact digital viewport limits. Camera focal lengths and panoramic FOVs were calibrated within Blender’s virtual space, enabling full pre-visualization of drone flight paths and alignment with physical spatial boundaries before aerial filming commenced.


Offshore drone flight paths were matchmoved and camera-tracked in Blender, aligning real-world footage momentum with the virtual environment. Telemetry data guided the camera trajectory from Victoria Harbour toward the physical site coordinates, producing a continuous vector transition between live-action spatial capture and procedurally generated 3D geometry.


Procedural 3D VFX & Motion Graphics Compositing - Blender to AE

High-resolution drone footage served as the spatial reference baseline during compositing. To maintain accuracy, 3D camera tracking was utilised to integrate complex urban overlays over the matchmoved footage. Geographic data was also processed in Blender to generate a procedural point cloud city morphing effect, creating transitions between the live-action footage and the virtual environment. For the motion graphics, location introductions and contextual typography were crafted with premium metallic material textures and glowing light rays in After Effects, to achieve a cinematic finish.


Transit network data was proceduralized in Blender to generate dynamic vector geometry along CAD road outlines. Animation curves and time-remapping modifiers were then authored within Blender and After Effects, to synchronize the traffic flow visualizations with spatial audio cues, converting static transit routes into an accurate and multi-sensory data sequence.


The physical cityscape model functioned as the projection surface. The point cloud urban morphing, topographical elevation maps, animated urban zones, and illuminated infrastructure corridors were accurately aligned to the baseline measurements, enforcing a 1:1 physical scale and spatial fidelity between the projected virtual geometry and the physical relief substrate.

System architecture was consolidated into Touch Designer as a centralized media server for live site deployment, acting as the final recipient of the pre-optimized Blender and After Effects outputs. The master control handled high-bitrate multi-channel video playback and frame-accurate signal routing across multiple projection outputs, ensuring the pre-calculated Blender virtual camera coordinates translated flawlessly to the physical stage.

Final deployment required rigorous optical calibration on-site. Multi-display warping and edge-blending matrices were adjusted to eliminate geometric distortion across curved and relief surfaces, locking the procedurally generated Blender projection layers, laser paths, and spatial audio to the precise CAD reference markers established at the pipeline's inception.
