class GeomBuilder from IGESConvGeom
|
|
|
|
---Purpose : This class provides some useful basic tools to build IGESGeom
|
|
-- curves, especially :
|
|
-- define a curve in a plane in 3D space (ex. Circular or Conic
|
|
-- arc, or Copious Data defined in 2D)
|
|
-- make a CopiousData from a list of points/vectors
|
|
|
|
uses XY from gp, XYZ from gp, Trsf, Ax1, Ax2, Ax3,
|
|
HSequenceOfXYZ, HArray1OfXY, HArray1OfXYZ,
|
|
TransformationMatrix, CopiousData
|
|
|
|
raises DomainError
|

is
|
|
|
|
Create returns GeomBuilder;
|
|
---Purpose : Creates a GeomBuilder at initial state.
|
|
|
|
Clear (me : in out) is static;
|
|
---Purpose : Clears list of Points/Vectors and data about Transformation
|
|
|
|
AddXY (me : in out; val : XY from gp) is static;
|
|
---Purpose : Adds a XY (Z=0) to the list of points
|
|
|
|
AddXYZ (me : in out; val : XYZ from gp) is static;
|
|
---Purpose : Adds a XYZ to the list of points
|
|
|
|
AddVec (me : in out; val : XYZ from gp) is static;
|
|
---Purpose : Adds a Vector part to the list of points. It will be used
|
|
-- for CopiousData, datatype=3, only.
|
|
-- AddXY and AddXYZ consider a null vector part (0,0,0)
|
|
-- AddVec adds to the last added XY or XYZ
|
|
|
|
NbPoints (me) returns Integer is static;
|
|
---Purpose : Returns the count of already recorded points
|
|
|
|
Point (me; num : Integer) returns XYZ is static;
|
|
---Purpose : Returns a point given its rank (if added as XY, Z will be 0)
|
|
|
|
MakeCopiousData (me; datatype : Integer; polyline : Boolean = Standard_False)
|
|
returns mutable CopiousData
|
|
---Purpose : Makes a CopiousData with the list of recorded Points/Vectors
|
|
-- according to <datatype>, which must be 1,2 or 3
|
|
-- If <polyline> is given True, the CopiousData is coded as a
|
|
-- Polyline, but <datatype> must not be 3
|
|
-- <datatype> = 1 : Common Z is computed as average of all Z
|
|
-- <datatype> = 1 or 2 : Vectors are ignored
|
|
raises DomainError;
|
|
-- Error if : <datatype> is not 1,2 or 3; or NbPoints is 0
|
|
|
|
MakeXY (me) returns mutable HArray1OfXY is static;
|
|
---Purpose : Returns the list of points as a HArray1OfXY. Z are ignored.
|
|
|
|
MakeXYZ (me) returns mutable HArray1OfXYZ is static;
|
|
---Purpose : Returns the list of points as a HArray1OfXYZ
|
|
|
|
|
|
Position (me) returns Trsf from gp is static;
|
|
---Purpose : Returns the Position in which the method EvalXYZ will
|
|
-- evaluate a XYZ. It can be regarded as defining a local system.
|
|
-- It is initially set to Identity
|
|
|
|
SetPosition (me : in out; pos : Trsf from gp) is static;
|
|
---Purpose : Sets final position from an already defined Trsf
|
|
|
|
SetPosition (me : in out; pos : Ax3 from gp) is static;
|
|
---Purpose : Sets final position from an Ax3
|
|
|
|
SetPosition (me : in out; pos : Ax2 from gp) is static;
|
|
---Purpose : Sets final position from an Ax2
|
|
|
|
SetPosition (me : in out; pos : Ax1 from gp) is static;
|
|
---Purpose : Sets final position from an Ax1
|
|
-- (this means that origin point and Z-axis are defined, the
|
|
-- other axes are defined arbitrarily)
|
|
|
|
IsIdentity (me) returns Boolean is static;
|
|
---Purpose : Returns True if the Position is Identity
|
|
|
|
IsTranslation (me) returns Boolean is static;
|
|
---Purpose : Returns True if the Position is a Translation only
|
|
-- Remark : Identity and ZOnly will answer True
|
|
|
|
IsZOnly (me) returns Boolean is static;
|
|
---Purpose : Returns True if the Position corresponds to a Z-Displacement,
|
|
-- i.e. is a Translation only, and only on Z
|
|
-- Remark : Identity will answer True
|
|
|
|
EvalXYZ (me; val : XYZ from gp; X,Y,Z : out Real) is static;
|
|
---Purpose : Evaluates a XYZ value in the Position already defined.
|
|
-- Returns the transformed coordinates.
|
|
-- For a 2D definition, X,Y will then be used to define a XY and
|
|
-- Z will be regarded as a Z Displacement (can be ignored)
|
|
|
|
MakeTransformation (me; unit : Real = 1)
|
|
returns mutable TransformationMatrix is static;
|
|
---Purpose : Returns the IGES Transformation which corresponds to the
|
|
-- Position. Even if it is an Identity : IsIdentity should be
|
|
-- tested first.
|
|
-- <unit> is the unit value in which the model is created :
|
|
-- it is used to convert translation part
