INTRODUCING PHOTOSKETCH
Welcome to the PhotoSketch urban 3D modeling plugin for SketchUp. PhotoSketch is designed to make it easy for you to build phototextured 3D models of buildings directly from
photographs. We simplify the 3D modeling workflow by leveraging the SketchUp push-pull interface with computer vision and photogrammetry techniques. The PhotoSketch plugin merges
the benefits of automatic feature extraction, camera pose recovery, an intuitive sketching interface, and texture mapping to produce lightweight photorealistic 3D models of buildings. These
models, which typically consist of a few hundred polygons each, makes them well-suited for
use in high-performance visualization, online gaming, and web-based applications such as
Google Earth.

lightweight phototextured 3D models.
