C# 클래스 Axiom.Core.SceneManager

Empties the entire scene, inluding all SceneNodes, Entities, Lights, BillboardSets etc. Cameras are not deleted at this stage since they are still referenced by viewports, which are not destroyed during this process.

This method creates a new instance of a query object for this scene manager, for querying for objects within a AxisAlignedBox region.

Creates an animation which can be used to animate scene nodes.

An animation is a collection of 'tracks' which over time change the position / orientation of Node objects. In this case, the animation will likely have tracks to modify the position / orientation of SceneNode objects, e.g. to make objects move along a path.

You don't need to use an Animation object to move objects around - you can do it yourself using the methods of the Node in your application. However, when you need relatively complex scripted animation, this is the class to use since it will interpolate between keyframes for you and generally make the whole process easier to manage.

A single animation can affect multiple Node objects (each AnimationTrack affects a single Node). In addition, through animation blending a single Node can be affected by multiple animations, although this is more useful when performing skeletal animation (see Skeleton.CreateAnimation).

Create an AnimationState object for managing application of animations.

You can create Animation objects for animating SceneNode obejcts using the CreateAnimation method. However, in order to actually apply those animations you have to call methods on Node and Animation in a particular order (namely Node.ResetToInitialState and Animation.Apply). To make this easier and to help track the current time position of animations, the AnimationState object is provided.

So if you don't want to control animation application manually, call this method, update the returned object as you like every frame and let SceneManager apply the animation state for you.

Remember, AnimationState objects are disabled by default at creation time. Turn them on when you want them using their Enabled property.

Note that any SceneNode affected by this automatic animation will have it's state reset to it's initial position before application of the animation. Unless specifically modified using Node.SetInitialState the Node assumes it's initial state is at the origin. If you want the base state of the SceneNode to be elsewhere, make your changes to the node using the standard transform methods, then call SetInitialState to 'bake' this reference position into the node.

Overloaded method.

Creates a billboard set which can be uses for particles, sprites, etc.

Creates a camera to be managed by this scene manager.

This camera can be added to the scene at a later time using the AttachObject method of the SceneNode class.

This method creates a new instance of a query object for locating intersecting objects. See SceneQuery and IntersectionSceneQuery for full details.

Creates a light that will be managed by this scene manager.

Lights can either be in a fixed position and independent of the scene graph, or they can be attached to SceneNodes so they derive their position from the parent node. Either way, they are created using this method so that the SceneManager manages their existence.

Create a ManualObject, an object which you populate with geometry manually through a GL immediate-mode style interface.

Create MovableText, 3D floating text which can me moved around your scene

Creates a new Overlay.

Overlays can be used to render heads-up-displays (HUDs), menu systems, cockpits and any other 2D or 3D object you need to appear above the rest of the scene. See the Overlay class for more information.

NOTE: after creation, the Overlay is initially hidden. You can create as many overlays as you like ready to be displayed whenever. Just call Overlay.Show to display the overlay.

Creates an instance of a SceneNode.

Note that this does not add the SceneNode to the scene hierarchy. This method is for convenience, since it allows an instance to be created for which the SceneManager is responsible for allocating and releasing memory, which is convenient in complex scenes.

To include the returned SceneNode in the scene, use the AddChild method of the SceneNode which is to be it's parent.

Note that this method takes no parameters, and the node created is unnamed (it is actually given a generated name, which you can retrieve if you want). If you wish to create a node with a specific name, call the alternative method which takes a name parameter.

Creates an instance of a SceneNode with a given name.

Estimate the number of loading stages required to load the named world geometry.

Operates just like the version of this method which takes a filename, but operates on a stream instead. Note that since the stream is updated, you'll need to reset the stream or reopen it when it comes to loading it for real.

Estimate the number of loading stages required to load the named world geometry.

This method should be overridden by SceneManagers that provide custom world geometry that can take some time to load. They should return from this method a count of the number of stages of progress they can report on whilst loading. During real loading (setWorldGeomtry), they should call exactly that number of times when loading the geometry for real.

Internal method which parses the scene to find visible objects to render.

If you're implementing a custom scene manager, this is the most important method to override since it's here you can apply your custom world partitioning scheme. Once you have added the appropriate objects to the render queue, you can let the default SceneManager objects RenderVisibleObjects handle the actual rendering of the objects you pick.

Any visible objects will be added to a rendering queue, which is indexed by material in order to ensure objects with the same material are rendered together to minimise render state changes.

Asks the SceneManager to provide a suggested viewpoint from which the scene should be viewed.

Typically this method returns the origin unless a) world geometry has been loaded using SceneManager.LoadWorldGeometry and b) that world geometry has suggested 'start' points. If there is more than one viewpoint which the scene manager can suggest, it will always suggest the first one unless the random parameter is true.

Returns whether a static geometry instance with the given name exists. */

Render something as if it came from the current queue.

Loads the source of the 'world' geometry, i.e. the large, mainly static geometry making up the world e.g. rooms, landscape etc.

Depending on the type of SceneManager (subclasses will be specialized for particular world geometry types) you have requested via the Root or SceneManagerEnumerator classes, you can pass a filename to this method and it will attempt to load the world-level geometry for use. If you try to load an inappropriate type of world data an exception will be thrown. The default SceneManager cannot handle any sort of world geometry and so will always throw an exception. However subclasses like BspSceneManager can load particular types of world geometry e.g. "q3dm1.bsp".

Manual rendering method, for advanced users only.

This method allows you to send rendering commands through the pipeline on demand, bypassing any normal world processing. You should only use this if you really know what you're doing; the engine does lots of things for you that you really should let it do. However, there are times where it may be useful to have this manual interface, for example overlaying something on top of the scene.

Because this is an instant rendering method, timing is important. The best time to call it is from a RenderTarget event handler.

Don't call this method a lot, it's designed for rare (1 or 2 times per frame) use. Calling it regularly per frame will cause frame rate drops!

If set, only the selected node is rendered. To render all nodes, set to null.

Populate a light list with an ordered set of the lights which are closest

Note that since directional lights have no position, they are always considered closer than any point lights and as such will always take precedence.

Subclasses of the default SceneManager may wish to take into account other issues such as possible visibility of the light if that information is included in their data structures. This basic scenemanager simply orders by distance, eliminating those lights which are out of range.

The number of items in the list max exceed the maximum number of lights supported by the renderer, but the extraneous ones will never be used. In fact the limit will be imposed by Pass::getMaxSimultaneousLights.

Sets the source of the 'world' geometry, i.e. the large, mainly static geometry making up the world e.g. rooms, landscape etc. This function can be called before setWorldGeometry in a background thread, do to some slow tasks (e.g. IO) that do not involve the backend render system.

Depending on the type of SceneManager (subclasses will be specialised for particular world geometry types) you have requested via the Root or SceneManagerEnumerator classes, you can pass a stream to this method and it will attempt to load the world-level geometry for use. If the manager can only handle one input format the typeName parameter is not required. The stream passed will be read (and it's state updated).

Internal method for setting up the renderstate for a rendering pass.

Sets the size and count of textures used in texture-based shadows.

See ShadowTextureSize and ShadowTextureCount for details, this method just allows you to change both at once, which can save on reallocation if the textures have already been created.

Overloaded method.

Enables / disables a 'sky box' i.e. a 6-sided box at constant distance from the camera representing the sky.

You could create a sky box yourself using the standard mesh and entity methods, but this creates a plane which the camera can never get closer or further away from - it moves with the camera. (you could create this effect by creating a world box which was attached to the same SceneNode as the Camera too, but this would only apply to a single camera whereas this skybox applies to any camera using this scene manager).

The material you use for the skybox can either contain layers which are single textures, or they can be cubic textures, i.e. made up of 6 images, one for each plane of the cube. See the TextureLayer class for more information.

Overload.

Enables / disables a 'sky plane' i.e. a plane at constant distance from the camera representing the sky.

Internal method for creating shadow textures (texture-based shadows).

Utility method for creating the planes of a skybox.

Internal method for turning a regular pass into a shadow caster pass.

This is only used for texture shadows, basically we're trying to ensure that objects are rendered solid black. This method will usually return the standard solid black pass for all fixed function passes, but will merge in a vertex program and fudge the AutpoParamDataSource to set black lighting for passes with vertex programs.

Internal method for turning a regular pass into a shadow receiver pass.

This is only used for texture shadows, basically we're trying to ensure that objects are rendered with a projective texture. This method will usually return a standard single-texture pass for all fixed function passes, but will merge in a vertex program for passes with vertex programs.

Internal method for locating a list of lights which could be affecting the frustum.

Custom scene managers are encouraged to override this method to make use of their scene partitioning scheme to more efficiently locate lights, and to eliminate lights which may be occluded by word geometry.

Internal method for locating a list of shadow casters which could be affecting the frustum for a given light.

Custom scene managers are encouraged to override this method to add optimizations, and to add their own custom shadow casters (perhaps for world geometry)

Internal method for initializing the render queue.

Subclasses can use this to install their own RenderQueue implementation.

Internal method for setting up materials for shadows.

Advance method to increase the lights dirty counter due lights changed.

Scene manager tracking lights that affecting the frustum, if changes detected (the changes includes light list itself and the light's position and attenuation range), then increase the lights dirty counter. For some reason, you can call this method to force whole scene objects re-populate their light list. But near in mind, call to this method will harm performance, so should avoid if possible.

Prompts the class to send its contents to the renderer.

This method prompts the scene manager to send the contents of the scene it manages to the rendering pipeline, possibly preceded by some sorting, culling or other scene management tasks. Note that this method is not normally called directly by the user application; it is called automatically by the engine's rendering loop.

This function is intended to be used to render the shadows of transparent objects which have transparency_casts_shadows set to 'on' in their material

Sends visible objects found in FindVisibleObjects to the rendering engine.

Internal utility method for setting stencil state for rendering shadow volumes.

Internal method for setting the destination viewport for the next render.

Internal method for updating the scene graph ie the tree of SceneNode instances managed by this class.

This must be done before issuing objects to the rendering pipeline, since derived transformations from parent nodes are not updated until required. This SceneManager is a basic implementation which simply updates all nodes from the root. This ensures the scene is up to date but requires all the nodes to be updated even if they are not visible. Subclasses could trim this such that only potentially visible nodes are updated.

Protected method used by RenderVisibleObjects to deal with renderables which override the camera's own view / projection materices.

Internal method to validate whether a Pass should be allowed to render.

Called just before a pass is about to be used for rendering a group to allow the SceneManager to omit it if required. A return value of false skips this pass.
