ABSTRACT:
A method for computing, in a computer with a television terminal, spatially transformed locations for samples in three-dimensional image space, of which a two-dimensional view is afforded on the television terminal. The spatial transformation of sample locations allows objects to be rotated, precessed or translated on the viewing screen of the television terminal. The original locations of samples are considered to be along a path in image space proceeding from a starting point sample. A spatial transform of the starting point is computed. The successive vector differences between successive samples along the path are determined, and the various values of these vector differences are spatially transformed. Spatially transformed samples are successively generated along the spatially transformed path in image space by successively adding the spatially transformed vector differences to the spatially transformed starting point sample, in an accumulation procedure. Where the number of various values of vector differences is substantially smaller than the number of vector differences, the method is more efficient than spatially transforming the locations of samples individually, the measure of efficiency being the number of digital multiplications required for the number of sample locations spatially transformed.
