Iso contours module

The iso contours module is designed to compare the values in the simulation to standards or expectations.

The window contains 3 widgets :

the analysis widget contains an histogram,
the settings widget contains settings to define the filters applied to the image and the iso contours color map and segments,
the preview widget contains a preview of the current post processed image.

Using this module, the save button has the following options :

LDR output : the processed output (the image currently displayed on screen) saved to a *.png file.

Filters

In order to smooth the iso contours, you can apply a median filter or a gaussian filter to the simulation.

Iso contours

The iso contours and segments sections define what is actually analysed and how :

Analysed data

The channel defines which channel is analysed from the layer selected in the texture widget.

Color map

The mode, color map and contours color define the visual aspect of the output. The Mode defines how the isocontours are drawn in the image : see examples bellow.

Mode "Zones and Contours" : each zone is drawn using the same colour, contours are drawn in a given colour

Mode "Zones" : each zone is drawn using the same colour, contours are not drawn

Mode "Contours" : each isocontour is drawn in a different colour, background is uniform

Mode "Overlay" : each zone is drawn using the original colour, contours are drawn in a given colour

Segments

The iso lines are placed at specific values defined in the segments section.

The segments can be :

regularly spaced along the [min;max] range,
defined with custom percentages : the segments are defined with values in [0;1] that represent a % of the values in the range [min;max],
defined with custom raw values.

You can save, copy and import these segments to be able to reuse the same display settings in different simulations.
