Member Function Documentation

◆ get_force()

bool GeomDrawCallbackData::get_force ( ) const
inline

Returns true if any required data should be forced into memory if necessary to render the object, or false if the object should be omitted if some of the data is not available (at least until the data becomes available later).

Definition at line 50 of file geomDrawCallbackData.I.

◆ get_gsg()

GraphicsStateGuardianBase * GeomDrawCallbackData::get_gsg ( ) const
inline

Returns a pointer to the current GSG.

Definition at line 39 of file geomDrawCallbackData.I.

◆ get_lost_state()

bool GeomDrawCallbackData::get_lost_state ( ) const
inline

Returns the lost_state flag.

See set_lost_state().

Definition at line 71 of file geomDrawCallbackData.I.

Referenced by CullableObject::draw(), and CullableObject::draw_callback().

◆ get_object()

CullableObject * GeomDrawCallbackData::get_object ( ) const
inline

Returns a pointer to the particular object that is being drawn.

Definition at line 31 of file geomDrawCallbackData.I.

◆ set_lost_state()

void GeomDrawCallbackData::set_lost_state ( bool  lost_state)
inline

Sets the lost_state flag.

If this is true, the callback does not have to be quite so careful to clean up after itself; Panda will assume that the graphics state is in an unknown state after the callback has finished, and will issue all the necessary calls to restore it. If this is false, Panda will assume the callback will leave the graphics state exactly as it came in, and won't bother to try to restore it. The default is true.

Definition at line 63 of file geomDrawCallbackData.I.

◆ upcall()

void GeomDrawCallbackData::upcall ( )
virtual

You should make this call during the callback if you want to continue the normal rendering function that would have been done in the absence of a callback.

Specifically, this method will add the Geoms in this node to the list of renderable objects for drawing. If this callback was made on a CallbackNode, it doesn't actually do anything, since only a GeomNode holds geoms.

Reimplemented from CallbackData.
