This is a special kind of frame that pretends to be much larger than it actually is.
You can scroll through the frame, as if you're looking through a window at the larger frame beneath. All children of this frame node are scrolled and clipped as if they were children of the larger, virtual frame.
This is implemented as a specialization of PGVirtualFrame, which handles the meat of the virtual canvas. This class adds automatic support for scroll bars, and restricts the virtual transform to translate only (no scale or rotate).

void PandaNode::adjust_draw_mask | ( | DrawMask | show_mask, |
DrawMask | hide_mask, | ||
DrawMask | clear_mask | ||
) | [inherited] |
Adjusts the hide/show bits of this particular node.
These three parameters can be used to adjust the _draw_control_mask and _draw_show_mask independently, which work together to provide per-camera visibility for the node and its descendents.
_draw_control_mask indicates the bits in _draw_show_mask that are significant. Each different bit corresponds to a different camera (and these bits are assigned via Camera::set_camera_mask()).
Where _draw_control_mask has a 1 bit, a 1 bit in _draw_show_mask indicates the node is visible to that camera, and a 0 bit indicates the node is hidden to that camera. Where _draw_control_mask is 0, the node is hidden only if a parent node is hidden.
The meaning of the three parameters is as follows:
Wherever show_mask is 1, _draw_show_mask and _draw_control_mask will be set 1. Thus, show_mask indicates the set of cameras to which the node should be shown.
Wherever hide_mask is 1, _draw_show_mask will be set 0 and _draw_control_mask will be set 1. Thus, hide_mask indicates the set of cameras from which the node should be hidden.
Wherever clear_mask is 1, _draw_control_mask will be set 0. Thus, clear_mask indicates the set of cameras from which the hidden state should be inherited from a parent.

int TypedWritable::complete_pointers | ( | TypedWritable ** | p_list, |
BamReader * | manager | ||

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

This function will be called during the cull traversal to perform any additional operations that should be performed at cull time.

Note that this function will *not* be called unless set_cull_callback() is called in the constructor of the derived class. It is necessary to call set_cull_callback() to indicated that we require cull_callback() to be called.
By the time this function is called, the node has already passed the bounding-volume test for the viewing frustum, and the node's transform and state have already been applied to the indicated CullTraverserData object.

Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

Returns an object that can be used to walk through the list of children of the node.
When you intend to visit multiple children, using this is slightly faster than calling get_child() directly on the PandaNode, since this object avoids reopening the PipelineCycler each time.
This object also protects you from self-modifying loops (e.g. adding or removing children during traversal), since a virtual copy of the children is made ahead of time. The virtual copy is fast--it is a form of copy-on-write, so the list is not actually copied unless it is modified during the traversal.

Returns an object that can be used to walk through the list of children of the node.
When you intend to visit multiple children, using this is slightly faster than calling get_stashed() directly on the PandaNode, since this object avoids reopening the PipelineCycler each time.
This object also protects you from self-modifying loops (e.g. adding or removing children during traversal), since a virtual copy of the children is made ahead of time. The virtual copy is fast--it is a form of copy-on-write, so the list is not actually copied unless it is modified during the traversal.

Set the unique ID assigned to this PGItem.
It is the user's responsibility to ensure that this ID is unique.
Normally, this should not need to be called, as the PGItem will assign itself an ID when it is created, but this function allows the user to decide to redefine the ID to be something possibly more meaningful.
void PandaNode::set_internal_bounds | ( | const BoundingVolume * | volume | ) | [protected, inherited] |
This is provided as an alternate way for a node to set its own internal bounds, rather than overloading compute_internal_bounds().

Sets the "into" CollideMask.
This specifies the set of bits that must be shared with a CollisionNode's "from" CollideMask in order for the CollisionNode to detect a collision with this particular node.
The actual CollideMask that will be set is masked by the return value from get_legal_collide_mask(). Thus, the into_collide_mask cannot be set to anything other than nonzero except for those types of nodes that can be collided into, such as CollisionNodes and GeomNodes.

void PandaNode::set_overall_hidden | ( | bool | hidden | ) | [inline, inherited] |
Sets or clears the hidden flag.
When the hidden flag is true, the node and all of its children are invisible to all cameras, regardless of the setting of any draw masks. Setting the hidden flag to false restores the previous visibility as established by the draw masks.
This actually works by twiddling the reserved _overall_bit in the node's draw mask, which has special meaning.

void PandaNode::set_unexpected_change | ( | unsigned int | flags | ) | [inherited] |
Sets one or more of the PandaNode::UnexpectedChange bits on, indicating that the corresponding property should not change again on this node.
Once one of these bits has been set, if the property changes, an assertion failure will be raised, which is designed to assist the developer in identifying the troublesome code that modified the property unexpectedly.
The input parameter is the union of bits that are to be set. To clear these bits later, use clear_unexpected_change().
Since this is a developer debugging tool only, this function does nothing in a production (NDEBUG) build.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
