TLDR
An algorithm to scan convert a line using method of deviation on hexagonal grid using only integer arithmetic to visualize design ideas through animation and photorealistic renderings and simulate how a design will perform in the real world in CAD tool with less aliasing artifact.
Abstract
In this paper an algorithm to scan convert a line using method of deviation on hexagonal grid is proposed. The method of deviation computes pixel nearest to analog line using only integer arithmetic. The proposed algorithm is compared favorably with the latest line drawing algorithm on a hexagonal grid. The main advantage of the proposed approach is that the same may be applied to an arbitrary curve. Owing to this approach we may visualize design ideas through animation and photorealistic renderings, and simulate how a design will perform in the real world in CAD tool with less aliasing artifact.

Bresenham's algorithm with Grey scale

TL;DR: The control parameter in Bresenham's algorithm, when interpreted as a measure of distance from a straight line boundary, gives a weighted average of the intensities on each side of the line that can be used to produce an aesthetically pleasing visual effect with modern display devices.

Fast line scan-conversion

TL;DR: In this paper an algorithm is developed based on the original Bresenham scan-conversion together with the symmetry first noted by Gardner [18] and a recent double-step technique that results in a speed-up of scan- Conversion by a factor of approximately 4.
