class MeshPrsBuilder from MeshVS inherits PrsBuilder from MeshVS
---Purpose: This class provides methods to compute base mesh presentation
uses
Integer from Standard,
Boolean from Standard,
Presentation from Prs3d,
PrsBuilder from MeshVS,
Mesh from MeshVS,
MeshPtr from MeshVS,
DisplayModeFlags from MeshVS,
DataSource from MeshVS,
BuilderPriority from MeshVS,
Drawer from MeshVS,
HArray1OfSequenceOfInteger from MeshVS,
MaterialAspect from Graphic3d,
AspectFillArea3d from Graphic3d,
AspectLine3d from Graphic3d,
AspectMarker3d from Graphic3d,
Array1OfReal from TColStd,
ArrayOfPolylines from Graphic3d,
ArrayOfPolygons from Graphic3d,
ArrayOfPrimitives from Graphic3d,
PackedMapOfInteger from TColStd
is
Create ( Parent : Mesh from MeshVS;
Flags : DisplayModeFlags from MeshVS = MeshVS_DMF_OCCMask;
DS : DataSource from MeshVS = 0;
Id : Integer = -1;
Priority : BuilderPriority from MeshVS = MeshVS_BP_Mesh ) returns mutable MeshPrsBuilder from MeshVS;
---Purpose: Creates builder with certain display mode flags, data source, ID and priority
Build ( me; Prs : Presentation from Prs3d;
IDs : PackedMapOfInteger;
IDsToExclude: in out PackedMapOfInteger;
IsElement : Boolean;
DisplayMode : Integer ) is virtual;
---Purpose: Builds base mesh presentation by calling the methods below
BuildNodes ( me; Prs : Presentation from Prs3d;
IDs : PackedMapOfInteger;
IDsToExclude: in out PackedMapOfInteger;
DisplayMode : Integer ) is virtual;
---Purpose: Builds nodes presentation
BuildElements ( me; Prs : Presentation from Prs3d;
IDs : PackedMapOfInteger;
IDsToExclude: in out PackedMapOfInteger;
DisplayMode : Integer ) is virtual;
---Purpose: Builds elements presentation
BuildHilightPrs ( me; Prs : Presentation from Prs3d;
IDs : PackedMapOfInteger;
IsElement : Boolean
) is virtual;
---Purpose: Builds presentation of hilighted entity
AddLinkPrs ( me; theCoords : Array1OfReal from TColStd;
theLines : ArrayOfPolylines from Graphic3d;
IsShrinked : Boolean;
ShrinkCoef : Real
) is protected;
---Purpose: Add to array of polylines some lines representing link

) is protected;
---Purpose: Add to array of polygons a polygon representing face
AddVolumePrs ( myclass; Topo : HArray1OfSequenceOfInteger from MeshVS;
Nodes : Array1OfReal from TColStd;
NbNodes : Integer;
Array : ArrayOfPrimitives from Graphic3d;
IsReflected : Boolean;
IsShrinked : Boolean;
IsSelect : Boolean;
ShrinkCoef : Real );
---Purpose: Add to array polygons or polylines representing volume
HowManyPrimitives( myclass; Topo : HArray1OfSequenceOfInteger from MeshVS;
AsPolygons : Boolean;
IsSelect : Boolean;
NbNodes : Integer;
Vertices, Bounds : out Integer );
---Purpose: Calculate how many polygons or polylines are necessary to draw passed topology
DrawArrays ( me; Prs : Presentation from Prs3d;
thePolygons : ArrayOfPolygons from Graphic3d;
theLines : ArrayOfPolylines from Graphic3d;
theLinkLines : ArrayOfPolylines from Graphic3d;
theVolumesInShad : ArrayOfPolygons from Graphic3d;
IsPolygonsEdgesOff : Boolean;
IsSelected : Boolean;
theFillAsp : AspectFillArea3d from Graphic3d;
theLineAsp : AspectLine3d from Graphic3d
) is protected;
---Purpose: Draw array of polygons and polylines in the certain order according to transparency
CalculateCenter ( myclass; theCoords : Array1OfReal from TColStd;
NbNodes : Integer;
xG, yG, zG : out Real ) is protected;
---Purpose: Default calculation of center of face or link. This method if useful for shrink mode presentation
-- theCoords is array of nodes co-ordinates in the strict order X1, Y1, Z1, X2...
-- NbNodes is number of nodes an element consist of
-- xG, yG, zG are co-ordinates of center whose will be returned
