1. A computer-implemented method of displaying a simulated three-dimensional scene without performing three-dimensional rendering, comprising:

  • storing first computer-readable data representative of the display of a background scene defining a plurality of locations, said background scene corresponding to a two-dimensional array of pixels;

    storing second computer-readable data representative of at least a first figure;

    storing third computer-readable data for providing a plurality of scaling factors associated with at least some of said locations, said step of storing said third computer-readable data includes storing (1) a first set of scaling factors corresponding to a first plurality of said pixels, and (2) storing a second set of scaling factors corresponding to a second plurality of said pixels, wherein there is at least one pixel common to said first and second pluralities of pixels;

    receiving, in a computer, user input indicating a location on said background scene at which said user wishes to position said figure;

    displaying, under computer control, an image which is the combination of a first image of at least a portion of said background scene with a second image of at least a portion of said figure, wherein said second image is scaled by a scaling factor which is selected from said plurality of scaling factors in response to said location indicated by said user input and wherein said image is located, with respect to said background scene, substantially near said location indicated by said user input.
