madmapper output to projector not in full screen mode

You have to install the plugin for your version of Blender. Keep in mind the number of vanishing points you have, different options will give you different results. Open the image and use fSpy to calibrate focal length, camera position, center point.

Keep in mind that you need to define 2 or 3 sets of vanishing points (lines that are parallel in reality but that would eventually converge when projected to 2D perspective. While watching the real, scene that should now have the placeholder image projected on it, trace as many straight lines as you can. Now you must draw lines that will help you understand the scene when you import the image into fSpy. The idea is to place yourself inside the projector so you can obtain an image of what the projector 'sees'. Enter full screen with the following commands alt+F9 and alt+F11. Drag that window into the second display (the projector). While still in the UV/Image Editor go to View -> Duplicate Area into New Window.

Go to Blender-> UV/Image Editor, create a new image matching the projector and render size, enter paint mode, set radius to 1 and paint stroke to line (choose high contrast background/line), and draw diagonals precisely to mark center and corners.Open Blender, set the render size to match projector.Based on the the example in the previously mentioned link by stuffmatic, the workflow is as follows:ĬREATE A PLACEHOLDER IMAGE: Use any drawing software that allows you to work in full screen mode. If you want to use fSpy (because its better).
