This class implements the following algorithms used
to create a ConicalSurface from Geom.
* Create a ConicalSurface parallel to another and passing
through a point.
* Create a ConicalSurface parallel to another at a distance
<Dist>.
* Create a ConicalSurface by 4 points.
* Create a ConicalSurface by its axis and 2 points.
* Create a ConicalSurface by 2 points and 2 radius.
The local coordinate system of the ConicalSurface is defined
with an axis placement (see class ElementarySurface).
The "ZAxis" is the symmetry axis of the ConicalSurface,
it gives the direction of increasing parametric value V.
The apex of the surface is on the negative side of this axis.
The parametrization range is :
U [0, 2*PI], V ]-infinite, + infinite[
The "XAxis" and the "YAxis" define the placement plane of the
surface (Z = 0, and parametric value V = 0) perpendicular to
the symmetry axis. The "XAxis" defines the origin of the
parameter U = 0. The trigonometric sense gives the positive
orientation for the parameter U.
When you create a ConicalSurface the U and V directions of
parametrization are such that at each point of the surface the
normal is oriented towards the "outside region".

GC_MakeConicalSurface (const gp_Ax2 &A2, const Standard_Real Ang, const Standard_Real Radius) | |
A2 defines the local coordinate system of the conical surface. Ang is the conical surface semi-angle ]0, PI/2[. Radius is the radius of the circle Viso in the placement plane of the conical surface defined with "XAxis" and "YAxis". The "ZDirection" of A2 defines the direction of the surface's axis of symmetry. If the location point of A2 is the apex of the surface Radius = 0 . At the creation the parametrization of the surface is defined such that the normal Vector (N = D1U ^ D1V) is oriented towards the "outside region" of the surface. Status is "NegativeRadius" if Radius < 0.0 or "BadAngle" if Ang < Resolution from gp or Ang >= PI/ - Resolution | |
GC_MakeConicalSurface (const gp_Cone &C) | |
Creates a ConicalSurface from a non persistent Cone from package gp. | |
GC_MakeConicalSurface (const gp_Cone &Cone, const gp_Pnt &Point) | |

GC_MakeConicalSurface (const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3, const gp_Pnt &P4) | |
Make a ConicalSurface from Geom <TheCone> passing through 3 Pnt <P1>,<P2>,<P3>. Its axis is <P1P2> and the radius of its base is the distance between <P3> and <P1P2>. The distance between <P4> and <P1P2> is the radius of the section passing through <P4>. An error iss raised if <P1>,<P2>,<P3>,<P4> are colinear or if <P3P4> is perpendicular to <P1P2> or <P3P4> is colinear to <P1P2>. | |
