Modeling for architecture: Photo matching in Blender

The most common starting point for architectural visualization projects is a CAD file with some kind of technical drawing of the visualization subject, or at least a few sketches. With a CAD file we will import the lines and work with them to transform 2d lines into a 3d model. But, sometimes the starting point of a modeling project will be something like a photo. This is a usual way to create facelift projects for old buildings, where the facade should be represented to add or change elements.

In Blender we have a few scripts that can make the camera match easily, but with only a few changes on the camera and a 3d mesh cube, we can already try to match a photo with a 3d model.

The tutorial below shows exactly how to do that with a building:

When the 3d cube of Blender is perfectly matched with the photo, the artist starts to add details and edges to create the windows and other facade elements. By the end, it will be quite easy to recreate the same facade with new details or changes for a face lift.

If you have a photo of a real building that must be modeled with Blender, the technique showed on the video will help to achieve a photo match quickly.
