Class TModel3D

Unit

a3dge.World3D

Declaration

type TModel3D = class(TObject)

Description

Base for models.

TModel3D implements an abstract class to define how objects will use models.

An instance of TModel3D is never created directly, instead a descendant class such as TPolygon should be created. This is because TModel3D is an abstract class which does not implement all methods; TModel3D also doesn't store any information about the model, this is the functionality introduced in descendants.

Description

Methods

	CONSTRUCTOR Create; VIRTUAL;
To force to override the constructor.

	FUNCTION BoundingSphereRadius: SINGLE; VIRTUAL;
Calculates the bounding sphere radius of the model. By default it returns zero. See also TObject3D.Radius Bounding sphere radius. TModel3D.BoundingBox Returns the bounding box limits.

	function BoundingBox: TBox; virtual;
Returns the bounding box limits. By default it returns zero in all parameters. See also TObject3D.BoundingBox The bounding box. TModel3D.BoundingSphereRadius Calculates the bounding sphere radius of the model.

	PROCEDURE Render (CONST aOwner: TObject3D); VIRTUAL; ABSTRACT;
Renders the object.

Properties

	property Name: String read fName write SetName;
Model name. Names are converted to lower-case.

	property Transparent: Boolean read fIsTransparent write fIsTransparent;
Has model transparent or translucent parts. Default is False.
