Standard_EXPORT | Geom_Plane (const gp_Ax3 &A3) |
Creates a plane located in 3D space with an axis placement three axis. The "ZDirection" of "A3" is the direction normal to the plane. The "Location" point of "A3" is the origin of the plane. The "XDirection" and "YDirection" of "A3" define the directions of the U isoparametric and V isoparametric curves. . | |
Standard_EXPORT | Geom_Plane (const gp_Pln &Pl) |
Creates a plane from a non transient plane from package gp. . | |
Standard_EXPORT | Geom_Plane (const gp_Pnt &P, const gp_Dir &V) |
P is the "Location" point or origin of the plane. V is the direction normal to the plane. . | |
Standard_EXPORT | Geom_Plane (const Standard_Real A, const Standard_Real B, const Standard_Real C, const Standard_Real D) |
Creates a plane from its cartesian equation : Ax + By + Cz + D = 0.0 Raised if Sqrt (A*A + B*B + C*C) <= Resolution from gp . | |
Standard_EXPORT void | SetPln (const gp_Pln &Pl) |
Set <me> so that <me> has the same geometric properties as Pl. . | |
Standard_EXPORT gp_Pln | Pln () const |
Converts this plane into a gp_Pln plane. . | |
virtual Standard_EXPORT void | UReverse () |
Changes the orientation of this plane in the u (or v) parametric direction. The bounds of the plane are not changed but the given parametric direction is reversed. Hence the orientation of the surface is reversed. . | |
Standard_EXPORT Standard_Real | UReversedParameter (const Standard_Real U) const |
Computes the u parameter on the modified plane, produced when reversing the u parametric of this plane, for any point of u parameter U on this plane. In the case of a plane, these methods return - -U. . | |
virtual Standard_EXPORT void | VReverse () |
Changes the orientation of this plane in the u (or v) parametric direction. The bounds of the plane are not changed but the given parametric direction is reversed. Hence the orientation of the surface is reversed. . | |
Standard_EXPORT Standard_Real | VReversedParameter (const Standard_Real V) const |
Computes the v parameter on the modified plane, produced when reversing the v parametric of this plane, for any point of v parameter V on this plane. In the case of a plane, these methods return -V. . | |
virtual Standard_EXPORT void | TransformParameters (Standard_Real &U, Standard_Real &V, const gp_Trsf &T) const |
Computes the parameters on the transformed surface for the transform of the point of parameters U,V on <me>. me->Transformed(T)->Value(U',V') is the same point as me->Value(U,V).Transformed(T) Where U',V' are the new values of U,V after calling me->TranformParameters(U,V,T) This methods multiplies U and V by T.ScaleFactor() . | |
virtual Standard_EXPORT gp_GTrsf2d | ParametricTransformation (const gp_Trsf &T) const |

Standard_EXPORT void | Bounds (Standard_Real &U1, Standard_Real &U2, Standard_Real &V1, Standard_Real &V2) const |
Returns the parametric bounds U1, U2, V1 and V2 of this plane. Because a plane is an infinite surface, the following is always true: - U1 = V1 = Standard_Real::RealFirst() - U2 = V2 = Standard_Real::RealLast(). . | |
