A3DCrvHyperbolaData

Functions

A3DStatus	A3DCrvHyperbolaGet
A3DStatus	A3DCrvHyperbolaCreate

Detailed Description

group a3d_crvhyperbola

Entity type is kA3DTypeCrvHyperbola.

Version

2.0

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

The A3DParameterizationData struct specified by the A3DCrvHyperbolaData::m_sParam member specifies reparameterization and trim for the curve.

Attention

In version 2.1 and earlier, values for the parameterization type named by the A3DCrvHyperbolaData::m_cParamType member are inverted compared to the corresponding values in the .
