TrinityBridge, Crowland, unrolled to soffit

3D Model

This odd model is a distorted model of Trinity Bridge in Lincolnshire. The original model was prepared for Lincolnshire County Council, to make a detailed record of the remarkable structure. Here, we have transformed every vertex by an algorithm that brings the soffit into a single plane.

This technique is very valuable, also in more typical structures, as it allows an overview of surfaces curving through 180 degrees or more.

We would normally crom the model to include only areas close to the surface of interest. Transformation of the whole model here is for illustrative purposes.
