CS123 | INTRODUCTION TO COMPUTER GRAPHICS Response to Stimuli (1/3) We draw a frequency response curve like this: l) to indicate how much a photoreceptor responds to light of uniform intensity for each wavelength To compute response to incoming band (frequency distribution) of light, like this: I l) l We multiply the curves, wavelength by wavelength, to compute receptor response to each amount of stimulus across spectrum l Andries van Dam Color 36/57
CS123 | INTRODUCTION TO COMPUTER GRAPHICS Response to Stimuli (2/3) Response Curve Incoming Light Distribution f ( l ) I ( l ) l l Product of functions R ( l ) l Gray area under product curve R represents how much receptor “sees,” i.e., total response to incoming light Let’s call this receptor red. Then: red perception = R(l)d(l) = I(l)f(l)dl Response Cell Applet: http://www.cs.brown.edu/exploratories/freeSoftware/repository/edu/brown/cs/exploratories/applets/spectru m/single_cell_response_guide.html Andries van Dam Color 37/57
