6.4 Scalability
activity.
The highest possible frame rate without any rendering is 2050 fps on the GF 8800
architecture and 530 fps on the reference system. Referring to diagram 6.12 the frame
rate decreases for concurrently rendered GPU based visualizations nearly on an exponential
curve.
For stream line based visualizations the limit of switching through the time has to
be considered as well. All lines will need exactly m render frames to fully evaluate for
the use of a n × m buffer for each time step. Due to our interactive implementation,
the user need not wait for a full line evaluation to get to a certain time position. The
course of the lines can be estimated even after the calculations of a few sampling points
and the time step can be changed independently from the line calculation.
