    Newbie: best practice for perspective correction?

    by BrooksT » Tue Oct 24, 2017 1:04 am

    I hope the attached is somewhat clear -- trying to draw a projector at height throwing onto a flat lawn type area and a cylindrical surface, from an angle. The images should appear undistorted from the normal of each surface... looking down onto the lawn or from an angle normal to the cylinder, you'd see a square and two circles.

    I'd like to correct for the projector's perspective so shapes appear "normal" to viewers. In this image, the actual circle and square will be pretty stretched.

    I can get this set up by warping the output manually by eye, but I feel like there must be a better, more repeatable way to approach the problem. Ideally one where I can get the surfaces/corrections once, and apply them to multiple quads with different inputs.

    Best way to set up MadMapper for this?
