Abstract
A series of points on a surface is projected onto pixels of an image along a projection axis. Furthermore, texture coordinates are allocated to the points as follows. First a normalized coordinate which is a ratio of the texture coordinate to a depth of the point along the projection axis is determined by linear interpolation. Displacement of the pixel is determined relative to a line in the image onto which a part of the surface, which has a constant depth in the projection direction, is projected. Subsequently, an interpolation function is calculated which interpolates the depth as a function of the displacement. The texture coordinate is determined by multiplication of the normalized coordinate by the depth. The image contribution by the point to an image content of the pixel is determined on the basis of the texture coordinate.
