[REQUEST]Implementing corresponding functions for IfcSpline
Elvira2227 opened this issue · comments
Is your feature request related to a problem? Please describe.
In #478 new unit tests were implemented for version IFC4X3_RC4 . For "bloss", "helmert", "sine", "cosine", "cubic", "viennese bend" curves we need to add corresponing functions to support them.
Describe the solution you'd like
The function convertIfcCurveSegment shoul be updated and new overloads for getPointOnCurve and getDirectionOfCurve should be added for:
- Sine curve (IfcSine) #553
- Cosine curve (IfcCosine)
The function for reading IfcThirdOrderPolynomialSpiral should be added for:
- Bloss curve #550
The function for reading IfcSeventhOrderPolynomialSpiral should be added for:
- Viennese Bend curve #552
The function for reading IfcSecondOrderPolynomialSpiral should be added for:
- Helmert curve #551
The function for reading IfcPolyonmialCurve should be added for:
- Cubic curve #539
Additional context
For examples of implementation please see #494 and #482
Great issue description!
A note to the developer: for first-, second-, and so on -orderpolynomial, a common function can be called by all with zeros at the corresponding locations.
