Curve On Surface

2.0

Entity type is:c:enumerator:~kA3DTypeCrvOnSurf.

For the canonical definition of this curve, see the “SerializeTransformationCurve” section of the*PRC Format Specification*.

A3DParameterizationDatamust have:c:member:A3DParameterizationData::m_dCoeffA <A3DParameterizationData.m_dCoeffA>set to 1,:c:member:A3DParameterizationData::m_dCoeffB <A3DParameterizationData.m_dCoeffB>set to 0 and an:c:struct:~A3DIntervalDataidentical to the one of:c:member:A3DCrvOnSurfData::m_pUVCurve <A3DCrvOnSurfData.m_pUVCurve>.

A3DMiscCartesianTransformationDatashould correspond to identity transformation.

A3DCrvOnSurfData::m_pUVCurvemust be a curve of type:c:enumerator:~kA3DTypeCrvLineor:c:enumerator:~kA3DTypeCrvNurbs.

Returns

A3D_SUCCESSon success, or an error code on failure
