5. Rendering 1960s - the visibility problem 1970s - raster graphics
Roberts (1963), Appel (1967) - hidden-line algorithms
Warnock (1969), Watkins (1970) - hidden-surface algorithms
Sutherland (1974) - visibility = sorting
1970s - raster graphics
Gouraud (1971) - diffuse lighting
Phong (1974) - specular lighting
Blinn (1974) - curved surfaces, texture
Catmull (1974) - Z-buffer
Crow (1977) - anti-aliasing
Shoup and Smith (1972) - paint programs
1970s

10. The graphics pipeline the traditional pipeline the new pipeline?
modeling
animation
rendering
the image-based graphics pipeline
when we get to image-based rendering, I’ll show you several other versions of this pipeline (mine a dn Mcohen’s from Sig97 panel)
3D scanning
motion capture
image-based
