The Open source fSpy application by Stuffmatic (available from https://fspy.io) is a utility that uses vanishing points on an image to calculate a 3D camera's approximate focal length, orientation, and position in 3D space required to produce the image. This technique is called Camera matching. fSpy is made specifically to simulate a 3D camera in Blender.

With "fSpy Project Importer" for DAZ Studio, you can directly open an fSpy project file and recreate not only the camera view, but also floor planes and a lot more. Our utility automatically sets up your 3D viewport to the correct aspect ratio, loads the image data into the background, creates the 3D camera, and for the Iray render engine, even creates shadow/reflection catching planes in your scene at the click of a mouse.

Scaling is also automatically calculated based on a reference line length set in fSpy so that any 3D elements that you add to your scene are correctly scaled no matter how big or small.

Additionally, the center of your 3D scene relates exactly to the axis center set in fSpy allowing you to load your 3d items in the precise location you want. The utility can also reorientate the entire scene to have it facing the front view which helps immensely with added 3D lighting.

Want to show off a 3D item on a coffee table in your photo? Simply draw a box along the tabletop in fSpy, and run our utility to recreate the exact camera settings and even add shadow/reflection catching to the tabletop without affecting the rest of the scene.
