orthogonal projection of 2D point to a 3D plane



2019 Community Moderator ElectionHow do I find the orthogonal projection of a point onto a planeFastest way to determine if an integer's square root is an integerIs floating point math broken?Projection on a plane using a 2*3 matrixHow do I find the orthogonal projection of a point onto a planeHow may I project vectors onto a plane defined by its orthogonal vector in Python?Projecting 3D points to 2D planeHow do I reverse-project 2D points on a plane into 3D?Ortho projection of 3D points with a vectorprojecting points onto a plane given by a normal and a pointProject 3D coordinates to a 2D plane

There are some answers already to projecting a 3D point to a 3D plane. (How do I find the orthogonal projection of a point onto a plane)



However, I wonder if it is possible to do an orthogonal projection of a 2D point onto a 3D plane (defined either by a normal and a point or as a 4D vector normal form)?



The context is that I have fitted a 3D plane to an image scene and then I want to do an orthogonal projection of a 2D image pixel coordinates onto this plane.

    There is no 2D points in 3D world. They are 3D, so approach is the same,
