8.16.2.1 IfcCurveInterpolationEnum

8.16.2.1.1 Semantic definition

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

Type	Description
`LINEAR`	Indicates that values between the defined values are to be found by linear interpolation.
`LOG_LINEAR`	Indicates that values between the defined values are to be found by linear interpolation of the natural logarithm (base e) of the values.
`LOG_LOG`	Indicates that values between the defined values are to be found by linear interpolation of the Briggs' logarithm (base 10) of the values.
`NOTDEFINED`	No interpolation information is provided
