Inheritance diagram for osg::Node:. Provides interface for most common node operations Composite Pattern. The default value is 0xffffffff all bits set. Construct a node. Initialize the parent list to empty, node name to "" and bounding sphere dirty flag to true. Mark this node's bounding sphere dirty. Forcing it to be computed on the next call to getBound. Used as a guide to the cull traversal. Set the initial bounding volume to use when computing the overall bounding volume. NodeMask osg::Node::getNodeMask const inline.

Get the number of parents of node. Returns the number of parents of this node. Get a single const parent of node. Parameters i index of the parent to get.

Returns the parent i. Get the list of node paths parent paths. ParentList osg::Node::getParents inline. Get the a copy of parent list of node. A copy is returned to prevent modification of the parent list. Returns NULL if a stateset is not attached. Get the list of matrices that transform this node from local coordinates to world coordinates. Otherwise, releases OpenGL objects for all graphics contexts. Convenience method that removes a given callback from a node, even if that callback is nested.

There is no error return in case the given callback is not found. Resize any per context GLObject buffers to specified size. Callback to allow users to override the default computation of bounding volume. A vector of std::string's which are used to describe the object. Public Types inherited from osg::Object. Get the parent list of node. Set update node callback, called during update traversal.

Get update node callback, called during update traversal. Viewed times. And is the first way is correct? Koban Koban 1 1 gold badge 5 5 silver badges 11 11 bronze badges. Add a comment.

Is it right that this code with overriding traverse method is not quite correct, because if there are multiple Cull Callbacks added to a node, traverse method is executed multiple time for each added collback and theoretically there should be not only 'nv.

Koban not sure what you mean, as you seem to mix the concepts of cull visitor and cull callback. Normally your node will be visited each frame by as many cull traversal as the number active Cameras. The default class used for each culling traversal is osgUtil::CullVisitor.

Convenience method that sets the cull callback of the node if it doesn't exist, or nest it into the existing one. Get the number of Children of this node which have culling disabled. Return true if this node can be culled by view frustum, occlusion or small feature culling during the cull traversal. Get the number of Children of this node which are or have OccluderNode 's. Set the node mask. Get the node Mask. Set the node's StateSet. Return the node's StateSet. Return the node's const StateSet.

Set the list of string descriptions. Get the description list of the node. Get the const description list of the const node. Get a single const description of the const node.

Get a single description of the node. Get the number of descriptions of the node. Add a description string to the node. Set the initial bounding volume to use when computing the overall bounding volume. Mark this node's bounding sphere dirty. Set the compute bound callback to override the default computeBound.

Get the compute bound callback. Get the const compute bound callback. Public Member Functions inherited from osg::Object. Construct an object. Object bool threadSafeRefUnref.

Copy constructor, optional CopyOp object can be used to control shallow vs deep copying of dynamic data. Convert 'this' into a Uniform pointer if Object is a Uniform , otherwise return 0. Set the name of object using a C style string. Get the name of object. Set the data variance of this object. Get the data variance of this object. Compute the DataVariance based on an assessment of callback etc. Set user data, data must be subclassed from Referenced to allow automatic memory handling.

Get user data. Get const user data. Public Member Functions inherited from osg::Referenced.
