Objective

For this project, the client wanted a 3D model representing the damage caused to a Ukrainian children’s library from bombing in 2022. The final model would be integrated into a digital animation to highlight the effects of war.

Approach

A point cloud existed on Sketchfab.com of the post-bombing state of the library. Though this was not downloadable, digital photogrammetry was carried out to create a reference model. This is where the point cloud or original model is rotated in the online viewer and screenshots are taken just as photography would be taken if doing photogrammetry in real life. Using this reference model, as well as a reconstruction model of the library pre-bombing, the damage was recreated digitally and the photogrammetry mesh of the impact crater was kept and retextured for use in the final product.

3D modeling and texture work was carried out in 3DS Max, Blender, and Adobe Substance Painter.

Outcome

The final post-bombing model was exported in the required file formats along with its textures. This was used by the client to create a digital animation highlighting the impacts of war.

Innovation

This project is another example of how digital photogrammetry can be used to turn an existing point cloud, mesh, or model into a reference in a reconstruction. It’s also a great example of how photogrammetry and 3D modeling can be used for Humanitarian purposes
