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.
