- Vertices specified after bbbbggggnnnnlllliiiinnnn and before eeeennnnddddlllliiiinnnn are interpreted as
- endpoints of a series of line segments. Use the vvvv routine to specify a
- vertex. The first vertex connects to the second; the second connects to
- the third; and so on until the next-to-last vertex connects to the last
- one. The last vertex does not connect to the first vertex. Use bbbbggggnnnncccclllloooo
- to connect the first and last points. All segments use the current
- linestyle, which is reset prior to the first segment and continues
- through subsequent segments.
-
- Between bbbbggggnnnnlllliiiinnnn and eeeennnnddddlllliiiinnnn, you can issue only the following Graphics
- Library routines: cccc, ccccoooolllloooorrrr, ccccppppaaaacccckkkk, llllmmmmbbbbiiiinnnndddd, llllmmmmccccoooolllloooo, llllmmmmddddeeeeffff, nnnn, RRRRGGGGBBBBccccoooollll, tttt,
- and vvvv. llllmmmmddddeeeeffff and llllmmmmbbbbiiiinnnndddd can be used to respecify only materials and
- their properties. If the color changes between a pair of vertices, the
- color of the line segment will be constant if the current shading model
- is FLAT and interpolated if the current shading model is GOURAU. In
- color map mode, the colors vary through the color map; to get reasonable
- results, the color map should contain a ramp.
-
- There is no limit to the number of vertices that can be specified between
- bbbbggggnnnnlllliiiinnnn and eeeennnnddddlllliiiinnnn. After eeeennnnddddlllliiiinnnn, the current graphics position is
- undefined.
-
- By default, line vertices are forced to the nearest pixel center prior to
- scan conversion. Line accuracy is improved when this coercion is
- defeated with the ssssuuuubbbbppppiiiixxxx command. Subpixel vertex positioning is
- especially important when lines are scan-converted with antialiasing
- enabled (see lllliiiinnnneeeessssmmmm).

- On the IRIS-4D B and G models, and on the Personal Iris without Turbo
- Graphics, if the color changes between a pair of vertices, the color of
- the line segment will be constant regardless of the current shading
- model.
-
- On the IRIS-4D GT and GTX models, if the color changes between a pair of
- vertices, the color of the line segment will be interpolated regardless
- of the current shading model.

-
- On the IRIS-4D B and G models, the linestyle is reset at the start of
- each segment, rather than only at the start of the first segment.
