Cologne Cathedral - with full interior 3D model
First of all, come and visit my new work in progress model. The official rebuild project of Cologne Cathedral in cooperation with the cathedral restauration workshop
And check out a nice reference of this model in a german animated film by Akkord Film.
This model is a 1:1 highly detailed reconstruction of the Cologne Cathedral based on 40 blueprints from the 19th century. I built the cathedral in roughly five month using SketchUp. It has full interior design exept the furnishing and some decor. Even the main spiral staircase is fully reconstructed to reach the different floor levels in the southern tower. You can access the whole triforium through various transitions.
The model has a full hierachy of components/instances and layers.
Other file formats (FBX, OBJ,...) are on demand because of the enormous exporting time and file size. This files can reach a size from 6 GB up to 20 GB depending on the level of detail you want.
