With photogrammetry (3D scans) it's possible to build high photo realistic 3D models based on photos of real world objects. Depending on the complexity of the object and the desired accuracy of the model, up to 100 - 150 images of one object are needed.
Software like Agisoft Metashape use these images and build a 3D model. ZBrush cleans and simplifys the generated mesh of the 3D model. And with Substance Designer the necessary textures like Roughness, Height, Normal, AO etc are made.
In the early 90ties I started with photography and always loved the image editing process afterwards. Many years later, in 2005, I discovered 3D computer graphics and created some simple 3D landscape images. Then I came across the 3D software "Blender 3D" and was flashed by all the features of this free open source software. Since then this software is my favourite toy - sometimes causing frustration but definately generating much more fun.
While at first I tried to render everthing I meanwhile focus on architcural visualization (stills) and on "Photogrammetry" - 3D scans of real world objects.
