Cssgrid timing table


The execution times for Cssgrid are essentially linearly proportional to the number of output data points (doubling the number of output data points will double the execution time). For smaller numbers of output data points, the number of input points is more of a time consideration, since the triangulation step represents a larger portion of the total time.

The following table is offered as an example of execution times. The times were obtained on a Sun sparc Ultra-1 running SunOS 5.5.1 using version SC4.2 of the C compiler:

Number of input points Number of output points Time in Secs.
400 400 0.57
1600 400 0.77
6400 400 1.66
400 1600 2.17
1600 1600 2.35
6400 1600 3.20
400 6400 8.32
1600 6400 8.79
6400 6400 9.68
400 25600 32.91
1600 25600 34.19
6400 25600 35.17
