Brdf acquisition with basis illumination
WebAt a given point on a surface the BRDF is a function of two directions, one toward the light and on To create a realistic image we need to characterize how light reflects off a … Webhighlight shifts. Since a BRDF measures how light is reflected, it must capture this view- and light- dependent nature of reflected light. Consequently, a BRDF is a function of …
