Description

Methods

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

This checks whether xDimension and zDimension are >= 2, xSpacing and zSpacing are > 0 and height has at least the required number of values. If this returns False then it is understood that ElevationGrid is not rendered, doesn't have any vertices/triangles etc.
