Abstract

A method adapts an output image to a shape of a display surface. First, a structured pattern is projected onto the display surface by a projector. An input image of the structured pattern is acquired by a camera in a fixed physical relationship to the projector. From the input image, a mesh of the structured pattern is determined in a coordinate frame of the projector. Coordinates of a texture are determined in the coordinate frame of the projector. The coordinates of the texture are updated according to the display region. The texture then mapped to the mesh, and the textured mesh is rendered on the display surface.
