• Translucent or transparent quality of computer-generated 3-D images with a complex of reflected scene among boundary surfaces may be visualized using a constructive solid geometry model (CSGM) and a ray tracing method (RTM) on a color CRT. Generally, the CSGM is composed of a combination of some primitives and quadratic surfaces. The RTM has been widely used as the principal means for displaying computer-generated 3-D images with reality.The effects of additive and pseudo-subtractive color mixings are compared with a view to examining the visual appearance of color and image quality of transparent objects on a color CRT. The relation between the degree of transparency and the value of depth level : a kind of parameter for taking stock of the total number of times of specular reflection at the surface of opaque objects and/or that of reflection and refraction at the border of transparent media is discussed from a viewpoint of color rendering and color shift.
