Member Function Documentation

context()

virtual OdGiContext* OdGiCommonDraw::context ( ) const

pure virtual

Returns the OdGiContext instance associated with this object.

Implemented in OdGiLayerTraitsTakerView, OdGiLayerTraitsTaker, OdGiWorldDraw_Dummy, OdGiViewportDraw_Dummy, OdGiBaseVectorizer, and OdGiWorldDrawImpl.

currentGiPath()

virtual const OdGiPathNode* OdGiCommonDraw::currentGiPath ( ) const

virtual

Returns the current drawable nesting graph.

Reimplemented in OdGiViewportDraw_, OdGiWorldDraw_, and OdGiBaseVectorizer.

deviation()

virtual double OdGiCommonDraw::deviation ( const OdGiDeviationType  deviationType, const OdGePoint3d &  pointOnCurve  ) const

pure virtual

Returns the recommended maximum deviation of the current vectorization for the specified point on a curve.

Parameters

deviationType	[in] Deviation type.
pointOnCurve	[in] Point on a curve.

Remarks

This function returns the recommended maximum difference (with respect to the current active viewport) between the actual curve or surface, and the tessellated curve or surface.

deviationType must be one of the following:

Value kOdGiMaxDevForCircle 0
kOdGiMaxDevForCurve 1
kOdGiMaxDevForBoundary 2
kOdGiMaxDevForIsoline 3 kOdGiMaxDevForFacet 4

Remarks

This function uses circle zoom percent or FacetRes as appropriate.

Implemented in OdGiLayerTraitsTakerView, OdGiDummyCommonDraw< OdGiViewportDraw >, OdGiDummyCommonDraw< OdGiWorldDraw_ >, OdGiDummyCommonDraw< OdGiWrapperViewportGeometry< OdGiViewportDraw_ > >, OdGiDummyCommonDraw< OdGiDummyViewportGeometry< OdGiViewportDraw_ > >, OdGiDummyCommonDraw< OdGiDummyWorldGeometry< OdGiWorldDraw_ > >, OdGiDummyCommonDraw< OdGiWorldDraw >, OdGiWrapperCommonDraw< OdGiViewportDraw >, OdGiWrapperCommonDraw< OdGiWorldDraw >, OdGiBaseVectorizerImpl, OdGiLayerTraitsTaker, and OdGiBaseVectorizer.

displayModelerSilhouettes()

virtual bool OdGiCommonDraw::displayModelerSilhouettes ( ) const

virtual

Returns whether silhouette curves should be generated (basically should return OdDbDatabase::getDISPSILH, but the behavior could be specialized).

isDragging()

virtual bool OdGiCommonDraw::isDragging ( ) const

pure virtual

Returns true if this vectorization process is the result of a "drag" operation.

Remarks

Implemented in OdGsBaseVectorizer, OdGiLayerTraitsTaker, and OdGiBaseVectorizer.

numberOfIsolines()

virtual OdUInt32 OdGiCommonDraw::numberOfIsolines ( ) const

pure virtual

Returns the number of isolines to be drawn on surfaces during this vectorization.

Implemented in OdGiLayerTraitsTakerView, OdGiLayerTraitsTaker, OdGiBaseVectorizer, and OdGiWorldDrawImpl.

ODRX_DECLARE_MEMBERS()

OdGiCommonDraw::ODRX_DECLARE_MEMBERS

(

OdGiCommonDraw

)

rawGeometry()

virtual OdGiGeometry& OdGiCommonDraw::rawGeometry ( ) const

pure virtual

Provides access to this object's "drawing interface."

Remarks

The "drawing interface" is a set of geometry functions used during the vectorization process.

Implemented in OdGiLayerTraitsTaker, OdGiWorldDraw_Dummy, OdGiViewportDraw_Dummy, OdGiWorldDraw_Stub, OdGiViewportDraw_Stub, OdGiBaseVectorizer, and OdGiWorldDrawImpl.

regenAbort()

virtual bool OdGiCommonDraw::regenAbort ( ) const

pure virtual

Returns true if and only if this vectorization process should be aborted.

Implemented in OdGiLayerTraitsTakerView, OdGsBaseVectorizer, OdGiLayerTraitsTaker, OdGiExtCalc, and OdGiBaseVectorizer.

regenType()

virtual OdGiRegenType OdGiCommonDraw::regenType ( ) const

pure virtual

Returns the regeneration type of the current vectorization process.

Remarks

regenType() returns one of the following:

Value eOdGiRegenTypeInvalid 0 kOdGiStandardDisplay 2 kOdGiHideOrShadeCommand 3 kOdGiRenderCommand 4 kOdGiForExplode 5 kOdGiSaveWorldDrawForProxy 6 kOdGiForExtents 7

Implemented in OdGiLayerTraitsTakerView, OdGiBaseVectorizerImpl, OdGiLayerTraitsTaker, OdGiExtCalc, and OdGiBaseVectorizer.

subEntityTraits()

virtual OdGiSubEntityTraits& OdGiCommonDraw::subEntityTraits ( ) const

pure virtual

Provides access to this object's subentity traits.

Remarks

This allows the modification of the vectorization attributes such as color, linetype, etc.

Implemented in OdGiLayerTraitsTaker, OdGiWorldDraw_Dummy, OdGiViewportDraw_Dummy, OdGiWorldDraw_Stub, OdGiViewportDraw_Stub, OdGiBaseVectorizer, and OdGiWorldDrawImpl.
