Member Function Documentation

analitycMode()

virtual OdUInt8 OdGiCollideProc::analitycMode ( ) const

pure virtual

Retrieves options that are used in the analytic mode.

Returns

options that are used in analytic mode. Must be implemented in derived classes.

enableAnalyticMode()

virtual void OdGiCollideProc::enableAnalyticMode ( OdUInt8  options )

pure virtual

Enables analytic mode for specified primitives. Must be implemented in derived classes.

Parameters

options

[in] Option for analytic mode.

extents()

virtual const OdGeExtents3d & OdGiCollideProc::extents ( ) const

pure virtual

Retrieves the extents of triangles that were collected during the OdGiCollideProc::kPhaseGatherInputData processing phase.

Returns

geometrical extents of the collected triangles.

linePrimitivesChecking()

virtual bool OdGiCollideProc::linePrimitivesChecking ( ) const

pure virtual

Checks whether line primitives should be checked. If line primitives checking is disabled, only triangles will be checked.

Returns

true if line primitives checking is enabled, false otherwise which means that only triangles are checked.

noFilter()

virtual bool OdGiCollideProc::noFilter ( ) const

pure virtual

Checks whether entity filtering is disabled.

Returns

true if entity filtering is disabled, false otherwise.

ODRX_DECLARE_MEMBERS()

OdGiCollideProc::ODRX_DECLARE_MEMBERS

(

OdGiCollideProc

)

processingPhase()

virtual ProcessingPhase OdGiCollideProc::processingPhase ( ) const

pure virtual

Retrieves the current processing phase.

Returns

current processing phase represented by the ProcessingPhase enumeration values.

processTriangles()

virtual void OdGiCollideProc::processTriangles ( )

pure virtual

Performs processing triangles that were gathered during conveyor node processing phases.

set()

virtual void OdGiCollideProc::set ( OdGsCollisionDetectionReactor *  pReactor, const OdGsCollisionDetectionContext *  pCtx = NULL  )

pure virtual

Associates this object with the collision detection reactor and collision detection context.

Parameters

pReactor	[in] Pointer to a custom object that detects collisions.
pCtx	[in] Pointer to the collision detection context.

setCheckWithDrawables()

virtual void OdGiCollideProc::setCheckWithDrawables ( OdGiPathNode const *const *  pInputList, OdUInt32  nInputListSize  )

pure virtual

Specifies an additional list of OdGiPathNode that is used in entity filtering during the OdGiCollideProc::kPhaseDetectIntersections processing phase;

Parameters

pInputList	[in] Pointer to a pointer to an input list of drawables.
nInputListSize	[in] Number of drawables in a list.

setDeviation() [1/2]

virtual void OdGiCollideProc::setDeviation ( const OdGeDoubleArray &  deviations )

pure virtual

Sets max deviation for curve tessellation.

Parameters

deviations

[in] Array with deviation values.

setDeviation() [2/2]

virtual void OdGiCollideProc::setDeviation ( const OdGiDeviation *  pDeviation )

pure virtual

Sets deviation object to obtain max deviation for curve tessellation.

Parameters

pDeviation

[in] Pointer to the deviation object.

setDrawContext()

virtual void OdGiCollideProc::setDrawContext ( OdGiConveyorContext *  pDrawCtx )

pure virtual

Sets the draw context object (to access to traits, etc).

Parameters

pDrawCtx

[in] Pointer to the draw context.

setExtentsExtension()

virtual void OdGiCollideProc::setExtentsExtension ( double  e )

pure virtual

Specifies extents extension.

Parameters

e	[in] Extents extension.

Remarks

This method is required for Clearance processing. If not to extend the extents, triangles may be filtered without clearance checking.

setInputDrawables()

virtual void OdGiCollideProc::setInputDrawables ( OdGiPathNode const *const *  pInputList, OdUInt32  nInputListSize  )

pure virtual

Specifies a list of OdGiPathNode items that are used in entity filtering.

Parameters

nInputListSize	[in] Number of drawables in a list.

setLinePrimitivesChecking()

virtual void OdGiCollideProc::setLinePrimitivesChecking ( bool  bCheck )

pure virtual

Specifies whether line primitives should be checked. If line primitives checking is disabled, only triangles will be checked.

Parameters

bCheck

[in] Flag that specifies whether line primitives should be checked.

setNoFilter()

virtual void OdGiCollideProc::setNoFilter ( bool  bNoFilter )

pure virtual

Disables entity filtering during.

Parameters

bNoFilter

[in] Flag that specifies whether

setProcessingPhase()

virtual void OdGiCollideProc::setProcessingPhase ( ProcessingPhase  )

pure virtual

Specifies the current processing phase that allows conveyor node collecting of triangles to different lists.

Parameters

ProcessingPhase

[in] Processing phase.
