Design Principles

"Leverage synergistic combinations of modelling techniques to achieve superior detail and accuracy in complex digital representations."

This approach addresses the limitations of single-technology solutions for intricate designs. By integrating data from various sources, designers can achieve a richer, more accurate digital model, which is crucial for documentation, analysis, and visualization in heritage preservation, architectural design, and urban planning.

What This Means for Your Design

Using different 3D scanning tools one after another, instead of just one, helps capture all the details of complicated old buildings like castles much better.
