In the mid-60's, J.E. Bresenham developed several computationally-inexpensive algorithms to draw two-dimensional graphics objects. The operation of the algorithms is obscure; see any standard graphics text for more information.
The NFB interface provides standard Bresenham line parameters for fast line drawing. The following routines are used for handling Bresenham objects:
| Routine | Description |
|---|---|
| nfbSetOptions(D3nfb) | set driver to gather multiple Bresenham lines before rendering them |
| ZeroSegs(D3nfb) | draw Bresenham lines |
