BACKGROUND Previous analysis of a single data set in acute pain following third molar extraction demonstrated a strong relationship between the speed of reduction of pain intensity and overall pain relief, as well as need for additional analgesia.

We have developed a new method for transforming images with per-pixel displacements into textures that have correct parallax when texture-mapped, in the usual way, onto polygons. Our new method results from factoring the 3-D image-warping equations of McMillan and Bishop into a prewarp followed by standard texture mapping. The pre-warp handles only the parallax effects resulting from the direct...
