Member Function Documentation

DestroyRuntimeCache()

virtual void ON_HLD_Object::DestroyRuntimeCache ( bool  bDelete )

pure virtual

EnableOccludingSection()

void ON_HLD_Object::EnableOccludingSection

(

bool

bEnable = true

)

Description: Enable Occluding Sections option for this object Parameters: bEnable - true enables Occluding Sections option, false disables

EnableSelectiveClipping()

void ON_HLD_Object::EnableSelectiveClipping ( bool  bEnable )

protected

This function is only called by This function is only called by ON_HiddenLineDrawingImplBase::SetSelectiveClipping()

Geometry()

virtual const ON_Geometry* ON_HLD_Object::Geometry ( ) const

pure virtual

Geometry() is in world coordinates if UseXform() is false, otherwise geometry is in object space coordinates (see GetXform() below).

GetXform()

const ON_Xform& ON_HLD_Object::GetXform

(

)

const

Description GetXform returns the mapping from object space to world coordinates. If UseXform() is false then GetXform() returns the identity transform.

OccludingSectionOption()

bool ON_HLD_Object::OccludingSectionOption

(

)

const

Returns true iff the OccludingSectionOption is enabled.

operator=()

ON_HLD_Object& ON_HLD_Object::operator= ( const ON_HLD_Object &  )

default

SelectiveClippingOption()

bool ON_HLD_Object::SelectiveClippingOption

(

)

const

UseXform()

bool ON_HLD_Object::UseXform

(

)

const

Description Returns true if there is an xform that must be applied to transform geom into the world coordinate system
