Abstract (en)
[origin: WO2017013068A1] The invention relates to a method and to a device for displaying a three-dimensional scene on a display surface having an arbitrary non-planar shape, for correct viewing by a user having a given position in a three-dimensional spatial reference system. The method comprises displaying a display image comprising pixels which represent the three-dimensional scene. The invention comprises: a first step (A1) of projecting a three-dimensional model of the display surface onto a projection plane (PL) in perspective, the projection in perspective having a projection centre which is dependent on the position of the user in the spatial reference system, making it possible to obtain a projection image (Iproj) of the display surface from the point of view of the user; and a second step (A2) of calculating a projection of the three-dimensional scene on the display surface using said projection image (Iproj).
