ScalarSettings

class cee.ug.ScalarSettings()

Specification of how to render scalar results on the model, on cutting planes, on isosurfaces and on particle traces.

Use this object to control the visual appearance of scalar results in the 3D viewer. You can specify which colorScheme to use for the color legend and how many levels (unique colors) it should have with levelCount. You can also control the legend’s scaling, either by using autoRangeMode or by specifying rangeMinimum and rangeMaximum.

Example: Setup a custom color legend

var modelSpec = myModel.modelSpec;

var resultId = modelSpec.fringesResultId;
if (resultId >= 0) {
    var scalarSettings = myModel.getScalarSettingsById(resultId);

    var min = myModel.getScalarResultMinimumValue(resultId);
    var max = myModel.getScalarResultMaximumValue(resultId);
    var range = max - min;

    // Setup custom scale 50% -> 100% of the range using a green to brown legend.
    scalarSettings.setRange(min + range*0.5, max);
    scalarSettings.colorScheme = cee.ug.ColorScheme.WHITE_TO_BROWN;
    scalarSettings.levelCount = 3;
}

Accessors

ScalarSettings.aboveRangeColor()

The color for the parts of the model that are above the current range.

Default is null, which means that the top color of the colorScheme will be used.

Note: Changing the colorScheme will set aboveRangeColor and belowRangeColor to null.

Return type:	Color3Like

ScalarSettings.aboveRangeColor(color)

Arguments:	color (`Color3Like`) – None
Return type:	void

ScalarSettings.autoRangeMode()

Auto range mode. Set this value with setAutoRange.

To disable auto range, set a manual range with setRange.

Return type:	AutoRangeMode

ScalarSettings.belowRangeColor()

The color for the parts of the model that are below the current range.

Default is null, which means that the bottom color of the colorScheme will be used.

Note: Changing the colorScheme will set aboveRangeColor and belowRangeColor to null.

Return type:	Color3Like

ScalarSettings.belowRangeColor(color)

Arguments:	color (`Color3Like`) – None
Return type:	void

ScalarSettings.colorMarkerArray()

Additional color legend markers that can be shown above or below the main markers in the legend.

Useful for describing above, below and undefined colors.

Example: Add a “No result” marker below the color legend:

scalarSettings.colorMarkerArray = [
    {
        position: cee.ug.LegendColorMarkerPosition.BELOW,
        color: new cee.Color3(0.5, 0.5, 0.5),

ScalarSettings.colorMarkerArray(colorMarkers)

Arguments:	colorMarkers (`unknown`) – None
Return type:	void

ScalarSettings.colorScheme()

The color scheme to use for the color legend and mapped colors on the model.

Use this property to set the color scheme to any of the pre-defined color schemes.

The colorScheme cannot be set to CUSTOM with this property. This is done with the setCustomContinuousColorArr() method or customFilledContoursColorArr property. colorScheme will return CUSTOM if one if these setters are used.

Note: Changing the colorScheme will set aboveRangeColor and belowRangeColor to null.

Return type:	ColorScheme

ScalarSettings.colorScheme(colorScheme)

Arguments:	colorScheme (`ColorScheme`) – None
Return type:	void

ScalarSettings.customContinuousColorArr()

Get the custom continuous color array if defined.

This is setup with the setCustomContinuousColorArr() method.

Return type:	[Color3Like]

ScalarSettings.customContinuousTickMarkArr()

Get the custom continuous tick mark array if defined.

This is setup with the setCustomContinuousTickMarks() method.

Return type:	[number]

ScalarSettings.customContinuousValueArr()

Get the custom continuous value array if defined.

This is setup with the setCustomContinuousColorArr() method.

Return type:	[number]

ScalarSettings.customFilledContoursColorArr()

Setup the color legend with the given level colors.

The color scheme will be set to CUSTOM, and the number of levels will be set to the length of the provided array.

Return type:	[Color3Like]

ScalarSettings.customFilledContoursColorArr(colorArr)

Arguments:	colorArr (`[Color3Like]`) – None
Return type:	void

ScalarSettings.filledContoursColorArr()

Get the colors of the current color legend (if in levels mode)

If levelCount > 0, this will return the colors for each level on the color legend, starting from the bottom of the legend.

Note: If not using customFilledContoursColorArr, the color legend info needs to be received from the server before this method will return valid info, so make sure the current update of display model is fully completed.

Return type:	[Color3Like]

ScalarSettings.filteringRangeMaximum()

The maximum value the result needs to have to be visible when filtering is enabled. This will be undefined if filtering is disabled.

Return type:	number

ScalarSettings.isFilteringEnabled()

Whether filtering of this scalar result is enabled.

Return type:	boolean

ScalarSettings.legendVisibilityMode()

Specifies the visibility of the color legend.

The legend can be set to appear if used by any part in the model (AUTO, default), to always be shown (ALWAYS) or to never be shown (NEVER)

Return type:	LegendVisibilityMode

ScalarSettings.legendVisibilityMode(mode)

Arguments:	mode (`LegendVisibilityMode`) – None
Return type:	void

ScalarSettings.levelCount()

The number of levels (unique colors) in the color legend.

If you want a continuous (smooth) legend, set the number of levels to 0. This will create a continuous legend with tick marks at round numbers.

Return type:	number

ScalarSettings.levelCount(numLevels)

Arguments:	numLevels (`number`) – None
Return type:	void

ScalarSettings.logarithmicMapping()

If true, a logarithmic range will be used for the color legend and results mapping. If false, a linear mapping will be used.

Return type:	boolean

ScalarSettings.logarithmicMapping(logarithmicMapping)

Arguments:	logarithmicMapping (`boolean`) – None
Return type:	void

ScalarSettings.nodeAveragedValues()

Specify if the scalar result should be shown as a node averaged result or not.

If false (default) the result is shown as is computed. If true, a node averaged result will be shown that is derived from the original result.

Also, setting this value for a result used to compute a feature extraction (like isovolume) affects the way the feature extraction is generated. For example, for per-element result mapping, the isosurface will be generated as a smooth node-averaged surface when this is set to true, instead of the usual “blocky” appearance.

Return type:	boolean

setCustomContinuousColorArr

ScalarSettings.setCustomContinuousColorArr(colorArr[, valueArr])

Arguments:	colorArr (`[Color3Like]`) – None valueArr (`[number]`) – optional None

Sets custom color scheme for a continuous color legend.

Specify an array of colors to use to create the interpolated continuous legend.

If values are specified (valueArr) the color will be set at that value and interpolated between the values. If no values are provided the specified colors will be distributed evenly between min and max.

The range will be adjusted if needed to include the specified values (if any).

Please note that there is no correlation between the values specified and the tick marks on the legend. The values specify the position of the color on the legend. The tick marks will be distributed on round numbers.
