Function Documentation

A3DStatus A3DCrvProjectPoint(const A3DCrvBase *pCrv, const A3DVector3dData *pPointToProject, A3DUns32 *puiNbSolutions, A3DDouble **ppdSolutionParameter, A3DDouble **ppdSolutionDistance)

This function projects a point on a curve.

ppdSolutionParameter and ppdSolutionDistance arrays give the parameter on the curve and the spatial distance between pPointToProject and the solution (on the curve). In order to free output arrays call again A3DCrvProjectPoint with curve sets to NULL.

Version
5.0

Parameters:
  • pCrv – [in] The input curve.
  • pPointToProject – [in] The input point to project on curve.
  • puiNbSolutions – [out] The number of returned solutions.
  • ppdSolutionParameter – [out] Array of parameters on the curve.
  • ppdSolutionDistance – [out] Array of spatial distances between pPointToProject and the solution (on the curve).
Return values:
  • A3D_SUCCESS –
  • A3D_ERROR –
Returns:

A3D_SUCCESS on success, or an error code on failure
A3DStatus A3DSurfProjectPoint(const A3DSurfBase *pSurf, const A3DVector3dData *pPointToProject, A3DUns32 *puiNbSolutions, A3DVector2dData **ppdSolutionParameters, A3DDouble **ppdSolutionDistance)

This function projects a point on a surface The number of returned solutions is given by puiNbSolutions and for each one, ppdSolutionParameters and ppdSolutionDistance arrays give the 2D point in surface parametric domain and the spatial distance between pPointToProject and the solution (on the surface).

In order to free output arrays call again A3DSurfProjectPoint with surface sets to NULL.

Version
5.0

Parameters:
  • pSurf – [in] The input surface.
  • pPointToProject – [in] The input point to project on surface.
  • puiNbSolutions – [out] The number of returned solutions.
  • ppdSolutionParameters – [out] Array of 2D points in the surface parametric domain.
  • ppdSolutionDistance – [out] Array of spatial distances between pPointToProject and the solution (on the surface).
Return values:
  • A3D_SUCCESS –
  • A3D_ERROR –
Returns:

A3D_SUCCESS on success, or an error code on failure
A3DStatus A3DCrvLocalProjectPoint(const A3DCrvBase *pCrv, const A3DVector3dData *pPointToProject, A3DDouble dGuessParameter, A3DBool *pbFindSolution, A3DDouble *pdSolutionParameter, A3DDouble *pdSolutionDistance)

This function projects a point on a curve with a guess parameter pdSolutionParameter and pdSolutionDistance give the parameter on the curve and the spatial distance between pPointToProject and the solution (on the curve).

Version
5.0

Parameters:
  • pCrv – [in] The input curve.
  • pPointToProject – [in] The input point to project on curve.
  • dGuessParameter – [in] The input guess parameters.
  • pbFindSolution – [out] Result status.
  • pdSolutionParameter – [out] parameter solution.
  • pdSolutionDistance – [out] spatial distance (optional).
Return values:
  • A3D_SUCCESS –
  • A3D_INVALID_ENTITY_NULL –
  • A3D_CRV_INVALID_PARAMETER –
  • A3D_ERROR –
Returns:

A3D_SUCCESS on success, or an error code on failure
A3DStatus A3DSurfLocalProjectPoint(const A3DSurfBase *pSurf, const A3DVector3dData *pPointToProject, const A3DVector2dData *pGuessPoint, A3DBool *pbFindSolution, A3DVector2dData *pSolutionParameter, A3DDouble *pdSolutionDistance)

This function projects a point on a surface with a guess parameter pSolutionParameter and pdSolutionDistance give the 2D point in surface parametric domain and the spatial distance between pPointToProject and the solution (on the surface).

pGuessPoint must be contained by the domain of the surface.

Version
5.0

Parameters:
  • pSurf – [in] The input surface.
  • pPointToProject – [in] The input point to project on surface.
  • pGuessPoint – [in] The input guess parameters.
  • pbFindSolution – [out] Result status.
  • pSolutionParameter – [out] parameter solution.
  • pdSolutionDistance – [out] spatial distance (optional).
Return values:
  • A3D_SUCCESS –
  • A3D_INVALID_ENTITY_NULL –
  • A3D_SRF_INVALID_PARAMETERS –
  • A3D_ERROR –
Returns:

A3D_SUCCESS on success, or an error code on failure

Version
7.0

Parameters:
  • pCrv – [in] The curve: A3DCrvBase.
  • pOptInterval – [in] The interval of restriction of the curve (if NULL, the natural interval of the curve will be used).
