Member Function Documentation

intersectWith()

virtual IntersectionStatus OdGsCullingVolume::intersectWith ( const OdGsCullingPrimitive &  prim ) const

pure virtual

Intersection test between culling volume and culling primitive (returns complete and incomplete intersection statuses).

Parameters

prim	[in] Input primitive for culling detection.

Returns

one of the following intersection statuses: Value Description kIntersectNot 0 No intersection detected. kIntersectOk 1 Intersects with culling volume boundary. kIntersectIn 2 Culling volume primitive is completely inside culling volume boundary.

intersectWithOpt()

virtual bool OdGsCullingVolume::intersectWithOpt ( const OdGsCullingPrimitive &  prim ) const

pure virtual

Optimized intersection test between culling volume and culling primitive.

Parameters

prim	[in] Input primitive for culling detection.

Returns

true if the provided primitive intersects with this culling volume, false otherwise.

ODRX_DECLARE_MEMBERS()

OdGsCullingVolume::ODRX_DECLARE_MEMBERS

(

OdGsCullingVolume

)

projectionType()

virtual ProjectionType OdGsCullingVolume::projectionType ( ) const

pure virtual

Returns type of projection for this culling volume object.

Remarks

Value Description kProjOrtho 0 Orthogonal projection. kProjPerspective 1 Perspective projection.

transformBy()

virtual void OdGsCullingVolume::transformBy ( const OdGeMatrix3d &  xfm )

pure virtual

Transform culling volume by transformation matrix.

Parameters

xfm	[in] Xform matrix.
