Shading techniques should be wavelength dependent, a fact which has traditionally been ignored in computer graphics: colour is usually represented in t.erms of an RGB coordinate system, which is inappropriat.e and has demonstrable problems. The use of spectral refl ectances for materials in place of the RGB values in t.he shading comput.at.ions would solve these problems. Our techniqne proposes using piecewise cn hic polynomials to approximate the re fl ectance spectra. With this met. hod, we t… CONTINUE READING
