Detailed Description

This is a special DisplayRegion wrapper that actually includes a pair of DisplayRegions internally: the left and right eyes.

The DisplayRegion represented here does not have a physical association with the window, but it pretends it does. Instead, it maintains a pointer to the left and right DisplayRegions separately.

Operations on the StereoDisplayRegion object affect both left and right eyes together. To access the left or right eyes independently, use get_left_eye() and get_right_eye().

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void DisplayRegion::set_cull_callback ( CallbackObject object) [inline, inherited]

Sets the CallbackObject that will be notified when the DisplayRegion is visited during the cull traversal.

This callback will be made during the cull thread.

The cull traversal is responsible for determining which nodes are visible and within the view frustum, and for accumulating state and transform, and generally building up the list of CullableObjects that are to be eventually passed to the draw traversal for rendering.

At the time the cull traversal callback is made, the traversal for this DisplayRegion has not yet started.

The callback is passed an instance of a DisplayRegionCullCallbackData, which contains pointers to the current scene information, as well as the current DisplayRegion and GSG. The callback replaces* the normal cull behavior, so if your callback does nothing, the scene graph will not be traversed and therefore nothing will be drawn. If you wish the normal cull traversal to be performed for this DisplayRegion, you must call cbdata->upcall() from your callback.

void DisplayRegion::set_draw_callback ( CallbackObject object) [inline, inherited]

Sets the CallbackObject that will be notified when the contents of DisplayRegion is drawn during the draw traversal.

This callback will be made during the draw thread.

The draw traversal is responsible for actually issuing the commands to the graphics engine to draw primitives. Its job is to walk through the list of CullableObjects build up by the cull traversal, as quickly as possible, issuing the appropriate commands to draw each one.

At the time the draw traversal callback is made, the graphics state is in the initial state, and no projection matrix or modelview matrix is in effect. begin_scene() has not yet been called, and no objects have yet been drawn. However, the viewport has already been set to the appropriate part of the window, and the clear commands for this DisplayRegion (if any) have been issued.

The callback is passed an instance of a DisplayRegionDrawCallbackData, which contains pointers to the current scene information, as well as the current DisplayRegion and GSG. The callback replaces* the normal draw behavior, so if your callback does nothing, nothing in the DisplayRegion will be drawn. If you wish the draw traversal to continue to draw the contents of this DisplayRegion, you must call cbdata->upcall() from your callback.

SC_stereo - the left eye is set to SC_left, the right eye to SC_right, and both eyes are activated.

SC_left - the left eye is set to SC_left and activated; the right eye is deactivated.

SC_right - the right eye is set to SC_right and activated; the left eye is deactivated.

This may return false if the underlying renderer doesn't support pixel zooming, or if you have called this on a DisplayRegion that doesn't have both set_clear_color() and set_clear_depth() enabled.

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.
