problem 1:
Illustrate the main criteria to be considered in the design of a line drawing algorithm for raster graphics display?
problem 2:
Illustrate an algorithm to fill a series of pixels running from (x_{0}; y_{0}) to (x_{1}; y_{1}) which meets these criteria, describing why it does so. Answers must comprise of more than a fragment of pseudo-code.
problem 3:
A new volumetric exhibit stores an image as a three-dimensional array of volume elements or voxels. Re-formulate the design and implementation of the line-drawing algorithm to fill a series of voxels running from (x_{0}; y_{0}; z_{0}) to (x_{1}; y_{1}; z_{1}).
problem 4:
How this line-drawing algorithm would be used to draw Bezier curves in three dimensions?
