Title
Interactive lighting manipulation application on GPU
Abstract
We present a technique for relighting an image such that different areas of the image are illuminated with different combinations of lighting directions. The key idea is to capture illumination data using a lighting apparatus system such as Hawkins et al. [2004], calculate radial basis function interpolation of light constraints specified by users and render the calculated illumination result in realtime using GPU. The application can simulate the result of unnatural lighting conditions, for example, the image of a whole face lit from per pixel view dependence reflection angles or from gazing angles (see Fig. 1, a). The application can also render a high-resolution result at 1920 x 1080 in three to four minutes.
