Justein Geis, the renowned sketchup trainer, shows some useful tricks to generate a model out of any photo by applying in-built photo matching tool in sketchup.
This is one of the exclusive features of sketchup. By learning just one measurement, it is possible to generate a whole model.
Photo matching facilitates a modeler to model out of a photograph after importing it. The 3d perspective is matched from the photograph and thus the users get the ability to model over the image and get it to visually appear the same. From there, the modeler will be able to rotate around and model accordingly.
Process for Importing a Match Photo
While importing a match photo, just go to… Camera>Match New Photo…
On the other hand, you can go to.. File>Import, choose your photo and turn on the Use as New Match Photo option.
Process for modifying the Perspective Lines.
Once the photo is imported, it is necessary to fix your perspective lines. Your red lines will match lines on one face of your 3d object, and your green lines will match lines on another face. With the help of mouse button, zoom in and out to verify your lines are as precise as possible.
As soon as your lines are fixed, shift your origin point to a discernible place that is adjacent to you in the photograph. It will be the place from where the modeling will be started.
