Abstract
There is provided a method including obtaining an initial spatial coordinate of a pixel of an image to be projected. The method may also include generating a pre-warped spatial coordinate associated with the initial spatial coordinate. The pre-warped spatial coordinate may be calculated as a sum of a value of a warp path function at the initial spatial coordinate and a delta. Moreover, the method may include outputting the pre-warped spatial coordinate.
