Detailed Description

This class defines the functionality for viewport -dependent entity-level vectorization.

Remarks

Consider a circular cone. A circular cone can be drawn as a circle and two silhouette lines. The circle could be drawn with the subWorldDraw() function, but the silhouette lines are dependent on the view direction, and must be computed with by subViewportDraw().

Member Function Documentation

geometry()

virtual OdGiViewportGeometry & OdGiViewportDraw::geometry ( ) const

pure virtual

Returns the OdGiViewportGeometry object associated with this object.

Remarks

This instance contains the functions that can be used by an entity to vectorize itself.

Implemented in OdGiViewportDraw_.

isValidId()

virtual bool OdGiViewportDraw::isValidId ( const OdUInt32  viewportId ) const

pure virtual

Checks whether the specified Viewport ID is a valid Viewport ID.

Parameters

viewportId

[in] Viewport ID.

Returns

true if the specified Viewport ID is a valid Viewport ID, false otherwise.

Remarks

viewportId is typically obtained from viewport().viewportId().

Implemented in OdGiBaseVectorizer, and OdGiBaseVectorizerImpl.

ODRX_DECLARE_MEMBERS()

OdGiViewportDraw::ODRX_DECLARE_MEMBERS

(

OdGiViewportDraw

)

sequenceNumber()

virtual OdUInt32 OdGiViewportDraw::sequenceNumber ( ) const

pure virtual

Returns the number of viewports that have been deleted from the current database during this editing session.

Implemented in OdGiBaseVectorizer, and OdGiBaseVectorizerImpl.

viewport()

virtual OdGiViewport & OdGiViewportDraw::viewport ( ) const

pure virtual

Returns a reference to the OdGiViewport object associated with this object.

Remarks

The OdGiViewport contains information specific to the viewport being drawn.

Implemented in OdGiBaseVectorizer, and OdGiBaseVectorizerImpl.

viewportObjectId()

virtual OdDbStub * OdGiViewportDraw::viewportObjectId ( ) const

pure virtual

Returns the Object ID of the OdDbViewport object associated with this object.

Remarks

Returns NULL if TileMode == 1.

Implemented in OdGiBaseVectorizer, and OdGiBaseVectorizerImpl.
