What is 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 Bender.

This add-on assumes understanding of 1, 2 and 3 point perspectives as well as a working knowledge of Blender.


  • Dynamically match the camera in real time using perspective guides.

  • Choose from 1, 2 or 3 point perspective modes.

  • Determine scale of the scene using a measuring guide.

  • Animate the camera using keyframe buttons.

  • Match background image proportions.

  • Flatten horizon line automatically.

  • Customize colors and opacity of guide lines.

  • Freeze guides in place to prevent accidental changed.

  • Use the bundled Move Along View tool to help model 3D meshes from 2D sketches.

  • Change axes of vanishing points.

  • Change camera midpoints and camera target location.
