gp_Hypr () | |
Creates of an indefinite hyperbola. . | |
gp_Hypr (const gp_Ax2 &A2, const Standard_Real MajorRadius, const Standard_Real MinorRadius) | |
Creates a hyperbola with radii MajorRadius and MinorRadius, positioned in the space by the coordinate system A2 such that: - the origin of A2 is the center of the hyperbola, - the "X Direction" of A2 defines the major axis of the hyperbola, that is, the major radius MajorRadius is measured along this axis, and - the "Y Direction" of A2 defines the minor axis of the hyperbola, that is, the minor radius MinorRadius is measured along this axis. Note: This class does not prevent the creation of a hyperbola where: - MajorAxis is equal to MinorAxis, or - MajorAxis is less than MinorAxis. Exceptions Standard_ConstructionError if MajorAxis or MinorAxis is negative. Raises ConstructionError if MajorRadius < 0.0 or MinorRadius < 0.0 //! Raised if MajorRadius < 0.0 or MinorRadius < 0.0 . | |
void | SetAxis (const gp_Ax1 &A1) |
Modifies this hyperbola, by redefining its local coordinate system so that: - its origin and "main Direction" become those of the axis A1 (the "X Direction" and "Y Direction" are then recomputed in the same way as for any gp_Ax2). Raises ConstructionError if the direction of A1 is parallel to the direction of the "XAxis" of the hyperbola. . | |
