«Macla de dos cuboides abiertos» by the sculptor Jorge Oteiza. Located next to the apse of the old church of San Agustín, current seat of the Municipal Archive of Valladolid.
Made using a set of 174 photos captured with a Panasonic DMCTZ10 camera in .JPG format.
Photogrammetric survey was performed with Metashape resulting in a 1.2M Tris HP model. Thanks to a semi-automatic retopology with Instant Meshes, an LP model of 40.2K Quads was obtained.
The subsequent retouching as well as the baking of the texture maps was done in Blender.
Later it was revisited with a new set of photographs taken on a cloudy day. This time it is a set of 182 photos captured with a Xiaomi Mi5s smartphone in .RAW format and later developed with CameraRaw.
The photogrammetric survey was also carried out in Metashape, resulting in a 12M tris HP model.
A highly optimized manual retopology was done in Blender with a polygonage less than 10k Quads. It remains to perform the baking of textures to be able to render and spread this updated model.
