Detailed Description

Basic NodeVisitor implementation for rendering a scene.

This visitor traverses the scene graph, collecting transparent and opaque osg::Drawables into a depth sorted transparent bin and a state sorted opaque bin. The opaque bin is rendered first, and then the transparent bin is rendered in order from the furthest osg::Drawable from the eye to the one nearest the eye.

		value_type &	znear,
		value_type &	zfar
	)		const

inline

Clamp the projection float matrix to computed near and far values, use callback if it exists, otherwise use default CullVisitor implementation.

		value_type &	znear,
		value_type &	zfar
	)		const

◆ clampProjectionMatrixImplementation() [1/2]

virtual bool osgUtil::CullVisitor::clampProjectionMatrixImplementation	(	osg::Matrixf &	projection,
		double &	znear,
		double &	zfar
	)		const

virtual

CullVisitor's default clamping of the projection float matrix to computed near and far values.

Note, do not call this method directly, use clampProjectionMatrix(..) instead, unless you want to bypass the callback.

◆ clampProjectionMatrixImplementation() [2/2]

virtual bool osgUtil::CullVisitor::clampProjectionMatrixImplementation	(	osg::Matrixd &	projection,
		double &	znear,
		double &	zfar
	)		const

virtual

CullVisitor's default clamping of the projection double matrix to computed near and far values.

Note, do not call this method directly, use clampProjectionMatrix(..) instead, unless you want to bypass the callback.

◆ computeNearPlane()

void osgUtil::CullVisitor::computeNearPlane ( )

compute near plane based on the polgon intersection of primtives in near plane candidate list of drawables.

Note, you have to set ComputeNearFarMode to COMPUTE_NEAR_FAR_USING_PRIMITIVES to be able to near plane candidate drawables to be recorded by the cull traversal.

◆ create()

static CullVisitor* osgUtil::CullVisitor::create ( )

static

create a CullVisitor by cloning CullVisitor::prototype().

◆ getDistanceFromEyePoint()

virtual float osgUtil::CullVisitor::getDistanceFromEyePoint	(	const osg::Vec3 &	,
		bool
	)		const

virtual

Get the distance of a point from the eye point, distance value in the eye coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented than a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

◆ getDistanceToEyePoint()

virtual float osgUtil::CullVisitor::getDistanceToEyePoint	(	const osg::Vec3 &	,
		bool
	)		const

virtual

Get the distance from a point to the eye point, distance value in local coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented then a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

◆ getDistanceToViewPoint()

virtual float osgUtil::CullVisitor::getDistanceToViewPoint	(	const osg::Vec3 &	,
		bool
	)		const

virtual

Get the distance from a point to the view point, distance value in local coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceToViewPoint(pos) is not implemented then a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

◆ getEyePoint()

virtual osg::Vec3 osgUtil::CullVisitor::getEyePoint ( ) const

inlinevirtual

Get the eye point in local coordinates.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement.

Reimplemented from osg::NodeVisitor.

◆ getViewPoint()

virtual osg::Vec3 osgUtil::CullVisitor::getViewPoint ( ) const

inlinevirtual

Get the view point in local coordinates.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement.

Reimplemented from osg::NodeVisitor.

◆ META_NodeVisitor()

osgUtil::CullVisitor::META_NodeVisitor	(	osgUtil	,
		CullVisitor
	)		const

inline

Create a shallow copy of the CullVisitor, used by CullVisitor::create() to clone the prototype.

◆ operator=()

CullVisitor& osgUtil::CullVisitor::operator= ( const CullVisitor & )

inlineprotected

Prevent unwanted copy operator.

◆ popProjectionMatrix()

virtual void osgUtil::CullVisitor::popProjectionMatrix ( )

virtual

Re-implement CullStack's popProjectionMatrix() adding clamping of the projection matrix to the computed near and far.

◆ popStateSet()

void osgUtil::CullVisitor::popStateSet ( )

inline

Pop the top state set and hence associated state group.

Move the current state group to the parent of the popped state group.

◆ prototype()

static osg::ref_ptr<CullVisitor>& osgUtil::CullVisitor::prototype ( )

static

get the prototype singleton used by CullVisitor::create().

◆ pushStateSet()

void osgUtil::CullVisitor::pushStateSet ( const osg::StateSet * ss )

inline

Push state set on the current state group.

If the state exists in a child state group of the current state group then move the current state group to that child. Otherwise, create a new state group for the state set, add it to the current state group then move the current state group pointer to the new state group.

◆ reset()

virtual void osgUtil::CullVisitor::reset ( )

virtual

Method to call to reset visitor.

Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.
