Perspective Plotter is an interactive add-on for matching camera settings to reference images directly in the 3D viewport. It functions similarly to fSpy, allowing users to define perspective lines to automatically set the camera's focal length, location, and rotation in real time.

The tool supports one, two, and three-point perspective modes and includes a measuring guide to determine scene scale. Additional utilities let you match background image proportions, automatically flatten the horizon line, and keyframe the camera adjustments. A bundled 'Move Along View' tool assists in positioning vertices or objects along the viewing angle to build 3D geometry accurately from 2D reference images.
