Detailed Description

Scene culling class

Implements a scene culling algorithm using bounding spheres. The following code example illustrates using the CIvfCulling class:

 void CMyWindow::onInit()
 {
     m_culling = new CIvfCulling();
     m_scene = new CIvfComposite();
     m_camera = new CIvfCamera();
     .
     .
     m_culling->setComposite(m_scene);
     m_culling->setCullView(m_camera);
     .
     .
 }
 
 void CMyWindow::onRender()
 {
     m_culling->cull();
     m_camera->render();
     m_scene->render();
 }

Member Function Documentation

void CIvfCulling::cull (   )

Initiates the cull operation Culls the assigned composite objects against the the view frustum of the assigned view. When an object has been culled the culled flag is set to true, See also: setCulled. If the flag is set to true the culled object is not rendered the int the next render() operation. The cull flag is automatically set to false after a render() method.

int CIvfCulling::getCullCount (   )

Returns the number of objects culled

void CIvfCulling::setComposite (  CIvfComposite *  composite  )

Sets the composite to be culled (required)

void CIvfCulling::setCullView (  CIvfView *  view  )

Sets the view used to cull the composite (required)
