Parabolic Curve

Parent module: Curves Module

group a3d_crvparabola

Entity type is kA3DTypeCrvParabola.

Version

2.0

For the canonical definition of this curve and its corresponding parametric equation, see the “SerializeParabola” section of the .

The A3DParameterizationData struct specified by the A3DCrvParabolaData::m_sParam member specifies reparameterization and trim for the curve.

When A3DCrvParabolaData::m_cParamType is set to 1, X value must be taken as param2/sqrt(16*focus2+param2), and Y as corresponding value 2 * A3DCrvParabolaData::m_dFocal * sqrt( fabs(X) / A3DCrvParabolaData::m_dFocal ).

Attention

In version 2.1 and earlier, values for parameterization named in the A3DCrvParabolaData::m_cParamType member are inverted compared to the corresponding values in the .

Version

2.3

A3DParameterizationData allows for reparameterization and trim.
