Low resolution images are a very important element in a well-implemented
user interface for a Mandelbrot browser program. Users who wish to
zoom in to a known feature are often already familiar with the
appearance of the features in the desired area, and can effectively use
low resolution to view the images at intermediate zoom levels. Using
low resolution decreases the time taken to generate the image, and thus
the time taken to determine the location for the next zoom.
Some popular techniques which use low resolution are as follows:
Successive Refinement, in which the resolution of the image is
gradually increased over time.
Limited-Region Refinement allows the user to select a region of
the image and refine just that small region to a higher resolution.
The low-resolution view of the image allows the user to see where to
select an area for refinement.
