1. An image data processing apparatus comprising:

  • a storage to store a set of image data representing a three-dimensional scene;

    a data processor to sample data points from the set of image data representing the three-dimensional scene to generate projection data, the sampling based on the position of an image surface relative to the position of a presentation surface; and

    a projection device to project modulated light rays from the presentation surface onto the image surface based on the projection data and generating a three-dimensional image that is representative of the three-dimensional scene;

    wherein the data processor samples different data points from the same set of image data responsive to changes in the position of the image surface relative to the presentation surface to generate projection data that can be used to generate a three-dimensional image that is representative of the three-dimensional scene.
