Member Function Documentation

spot_light_node * openvrml::vrml97_node::spot_light_node::to_spot_light

(

)

const [virtual]

Cast to a spot_light_node.

Returns:

a pointer to the node.

Reimplemented from openvrml::node.

void openvrml::vrml97_node::spot_light_node::renderScoped

(

openvrml::viewer &

viewer

)

[virtual]

Render the scoped light.

Parameters:

viewer

a Viewer.

Todo:

This should be called before rendering any geometry in the scene. Since this is called from Scene::render before traversing the scene graph, the proper transformation matrix hasn't been set up. Somehow it needs to figure out the accumulated xforms of its parents and apply them before rendering. This is not easy with DEF/USEd nodes...

Reimplemented from openvrml::vrml97_node::abstract_light_node.

void openvrml::vrml97_node::spot_light_node::do_initialize

(

double

timestamp

)

throw (std::bad_alloc) [private, virtual]

Initialize.

Parameters:

timestamp

the current time.

Exceptions:

std::bad_alloc

if memory allocation fails.

Reimplemented from openvrml::node.

void openvrml::vrml97_node::spot_light_node::do_shutdown

(

double

timestamp

)

throw () [private, virtual]

Shut down.

Parameters:

timestamp

the current time.

Reimplemented from openvrml::node.
