Abstract
Computer artists and designers are using increasingly sophisticated software packages in the generation and manipulation of images. Many software tools use complex algorithms with a number of parameters to achieve specific visual results, requiring the user to have some understanding of the algorithm and the way in which the parameters control it. This paper looks at methods for manipulating parameters based on the metaphor of navigating a parameter space.
