Match a camera to an image with Perspective Plotter

Match a camera to an image with Perspective Plotter, an interactive Blender add-on for modelers, architects and artists. This is useful for creating 3D models from 2D sketches, matching a 3D scene to a 2D photo, or animating a camera dynamically.
Defining perspective lines in the viewport sets a camera’s focal length, location and position in real time. The add-on will also work with more than one camera in a scene.
Additional tools allow you to match a camera’s background image proportions, quickly move vertices or objects along the view line, and automatically flatten the horizon.
The add-on is inspired by the freely available fSpy application, with the added benefit of being directly inside Blender.
If you have any issues, questions, or a feature request, don’t hesitate to get in touch via [email protected] or by visiting my Blender Market page.
One thing I noticed is that the videos don’t show what happens when you zoom in (use mousewheel) while in camera view.
Blender will let you zoom in a good little bit, and this might help you with precision, similar to fspy’s shift+click.
Thanks for giving the tip MFletcher!
Is Perspective Plotter Addon also useful for turning pictures of people and animals into 3d figures?
As long as the image has some identifiable parallel lines or points that are perpendicular to each other – such as two eyes and perhaps the front and back legs if they are in a uniform pose, or something else in the image you can match to. Organic forms such as people and animals will be more challenging though. Email [email protected] and I can give some advice.
