Description

Methods

Protected function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override;
 
Public constructor Create(const AX3DName: String = ''; const ABaseUrl: String = ''); override;
 
Public function TexCoordField: TSFNode; override;
 
Public function SolidField: TSFBool; override;
 
Public function ConvexField: TSFBool; override;
 
Public function CrossSection3D(Index: integer): TVector3;

For given Index, return appropriate FdCrossIndex item as 3D vertex. That is, uses FdCrossIndex values as X, Z of 3D vertex and sets Y = 0 (that's how Extrusion is defined in VRML / X3D).

Public function SpineClosed: boolean;

Check is spine closed. This happens when "spine" field is non-empty and it's first and last points are equal.

Public function CrossSectionClosed: boolean;

Check is crossSection closed. This happens when "crossSection" field is non-empty and it's first and last points are equal.
