Description

Methods

Public constructor Create(const AX3DName: String = ''; const ABaseUrl: String = ''); override;
 
Public function IsNotEmpty: boolean;

Do we have (correct) data to render.

Checks whether - xDimension and zDimension are >= 2, - xSpacing and zSpacing are > 0 - height list has at least the required number of values.

Public function ColorField: TSFNode; override;
 
Public function InternalFogCoord: TMFFloat; override;
 
Public function AttribField: TMFNode; override;
 
Public function SolidField: TSFBool; override;
 
Public function FieldSetByEvent(const Event: TX3DEvent): TX3DField; override;
 
Public function Proxy(var State: TX3DGraphTraverseState): TAbstractGeometryNode; override;
 
Public function LocalBoundingBox(State: TX3DGraphTraverseState; ProxyGeometry: TAbstractGeometryNode; ProxyState: TX3DGraphTraverseState): TBox3D; override;
 
Public function VerticesCount(State: TX3DGraphTraverseState; ProxyGeometry: TAbstractGeometryNode; ProxyState: TX3DGraphTraverseState): Cardinal; override;
 
Public function TrianglesCount(State: TX3DGraphTraverseState; ProxyGeometry: TAbstractGeometryNode; ProxyState: TX3DGraphTraverseState): Cardinal; override;
 
Public class function InternalCreateTriangles( const AXDimension, AZDimension: Integer; const AXSpacing, AZSpacing: Single; const AHeight: TSingleList; const ATexCoord: TAbstractTextureCoordinateNode; const TriangulationIgnoreHeights: Boolean): TIndexedTriangleSetNode;

Create triangle set to render the elevation grid. Useful for - Proxy in this class - TCastleTerrain which wants direct TIndexedTriangleSetNode (faster to later update than to maintain TElevationGridNode).

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;
 
Public procedure SetAttrib(const Value: array of TAbstractVertexAttributeNode);
 
Public procedure SetHeight(const Value: array of Single); overload;
 
Public procedure SetHeight(const Value: TSingleList); overload;
