GUI Tutorial

Loading a FlowDataset

Push the "load FlowData" button. Search for a dataset .gri file with the file browser and click the open button.

Draw background

activates the texture representation.

Color channels

specifies which of the additional data channels should be used with the transferfunction.

Transfer function: creating a new point

Right click on the position where you want to create a new point and choose "new point" (is only possible if there is no point at that position).

Transfer function: deleting a point

Right click on a existing point and choose "delete point".

Transfer function: change the color of a point

Right click on a exsisting point and choose "set color".

Transfer function: saving the current color and alpha points

The points get saved automaticly each time they change.

Draw arrows

activates the arrow plot.

Quantity

specifies the number of arrows plotted in direction of the larger dimension fo the dataset.

Draw streamlines

activates the streamline representation.

Mode

specifies the integration method, Runge-Kutta or Euler.

dsep

the seedpoint separation distance of the streamline algorithm.
due to different dataset sizes it is calculated relative to the smaller dimension of the dataset (sidelength/dsep).

dtest

the minimal allowed streamline distance, realtive to the separation distance.

dt

the steplength used by the integration, realtive to the testdistance.

Period

the periodlength used by the intensity function in texture line mode.
