Syntax
class FDMXGDTFMeasurementBase : public UE::DMX::GDTF::FDMXGDTFNode
Remarks
The measurement defines the relation between the requested output by a control channel and the physically achieved intensity. XML node for measurement is
The order of the measurements corresponds to their ascending physical values. Additional definition for additive color mixing: It is assumed that the physical value 0 exists and has zero output. Additional definition for subtractive color mixing: The flag is removed with physical value 0 and it does not affect the beam. Physical value 100 is maximally inserted and affects the beam.
Note 1: Some fixtures may vary in color response. These fixtures define multiple measurement points and corresponding interpolations.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
EDMXGDTFMeasurementInterpolationTo | InterpolationTo | Interpolation scheme from the previous value.The currently defined values are : "Linear", "Step", "Log"; Default: Linear |
 |
float | LuminousIntensity | Used for additive color mixing: overall candela value for the enclosed set of measurement. |
 |
TArray< TSharedPtr< FDMXGDTFMeasurementPoint > > | MeasurementPointArray | As children the Measurement Collect has an optional list of a measurement point. |
 |
float | Physical | For additive color mixing: uniquely given emitter intensity DMX percentage. |
 |
float | Transmission | Used for subtractive color mixing: total amount of lighting energy passed at this insertion percentage. |
