Member Function Documentation

virtual bool VIEW::GLRenderer::init (  Scene &  scene  )  throw () [virtual]

Initialise the renderer, by calling the init method below This method is called by Scene::initializeGL.

bool VIEW::GLRenderer::isExtensionSupported (  const String &  extension  )  const throw ()

Test if a given opengl extension is supported by the current driver. Call this only after Scene::initializeGL();

void VIEW::GLRenderer::pickObjects1 (  Position  x1, Position  y1, Position  x2, Position  y2 )  throw ()

Pick geometric objects. Parameters: x1,y1,x2,y2  the rectangle of the selection

void VIEW::GLRenderer::pickObjects2 (  List< GeometricObject * > &  objects  )  throw ()

Pick geometric objects method2. Call this method after pickObjects1 and rendering the representations. Parameters: objects  returns the picked objects

void VIEW::GLRenderer::updateCamera (  const Camera *  camera = 0  )  throw ()

Update the camera position with gluLookAt, either from a given Camera, or from the default Stage.
