Abstract
The present invention provides a method, system, and computer program product for generating a digital image having spatially varying effects. A preexisting source image is selected and used to generate a three-dimensional texture volume by convolving the pixels of the selected source image with a predetermined convolution kernel. A display image having spatially varying effects is then generated using the pixels of the three-dimensional texture volume and the pixels of a reference image, where each pixel of the reference image acts as an index to the pixels of the three-dimensional texture volume. The display image may be generated by either copying pixels from the three-dimensional texture volume to a frame buffer or by blending pixels from the three-dimensional texture volume with the pixels of an image already stored in the frame buffer.
