Real-time rendering of 3-D scenes using subband 3-D warping
Three techniques for increasing the frame rates of three-dimensional warping, namely subsampling, wavelet baseband, and wavelet transform (including high frequencies) are presented. Additionally noninteger and integer splats are applied for the techniques. The Haar baseband and subsampling methods using integer splats; both produce excellent frame rates and perceptual quality of warped images.
