© Method and apparatus for displaying a translucent object.
Fi g . 1
© A method for displaying a translucent object on
a display screen is disclosed which includes a step
of displaying a translucent object by providing a
diffused transmitted light component (Itr) instead of a
diffused reflection light component (Idiff) and a
specular reflection light component (Ispec) as are
necessary for displaying an object as an opaque
object. A method for displaying a translucent object
on a screen is also disclosed which includes a step
of judging whether or not an object to be displayed
is to be displayed as a translucent object based
upon the relation of the viewpoint and a light source
(L1, L2) to the object to be displayed.
