示例1: apply
void ScreenMVCullVisitor::apply(Projection& node)
{
// push the culling mode.
pushCurrentMask();
// push the node's state.
StateSet* node_state = node.getStateSet();
if(node_state)
pushStateSet(node_state);
// record previous near and far values.
float previous_znear = _computed_znear;
float previous_zfar = _computed_zfar;
// take a copy of the current near plane candidates
DistanceMatrixDrawableMap previousNearPlaneCandidateMap;
previousNearPlaneCandidateMap.swap(_nearPlaneCandidateMap);
_computed_znear = FLT_MAX;
_computed_zfar = -FLT_MAX;
ref_ptr < RefMatrix > matrix = createOrReuseMatrix(node.getMatrix());
pushProjectionMatrix(matrix.get());
//OSG_NOTIFY(osg::INFO)<<"Push projection "<<*matrix<<std::endl;
// note do culling check after the frustum has been updated to ensure
// that the node is not culled prematurely.
bool status = _cullingStatus;
bool firstStatus = _firstCullStatus;

// pop the node's state off the render graph stack.
