Type definition

IfcCurveInterpolationEnum specifies the possible methods for the interpolation of property values given as a curve.

HISTORY  New type in IFC4.

Enumeration definition
ConstantDescription
LINEARIndicates that values between the defined values are to be found by linear interpolation.
LOG_LINEARIndicates that values between the defined values are to be found by linear interpolation of the natural logarithm (base e) of the values.
LOG_LOGIndicates that values between the defined values are to be found by linear interpolation of the Briggs' logarithm (base 10) of the values.
NOTDEFINEDNo interpolation information is provided
