|

* A generic interface to dispatch callbacks.
|
||||
*
|
||||
* All APIs that take a callback as argument also take a
|
||||
* CallbackHandler* which is used to dispatch the
|
||||
* callback: CallbackHandler::post() method is called from a service thread as soon
|
||||
* as possible (this will NEVER be the main thread), CallbackHandler::post()
|
||||
* is responsible for scheduling the callback onto the thread the
|
||||
* user desires.
|
||||
*
|
||||
* This is intended to make callbacks interoperate with
|
||||
* the platform/OS's own messaging system.
|
||||
*
|
||||
* CallbackHandler* can always be nullptr in which case the default handler is used. The
|
||||
* default handler always dispatches callbacks on filament's main thread opportunistically.
|
||||
*
|
||||
* Life time:
|
||||
* ---------
|
||||
*
|
||||
* Filament make no attempts to manage the life time of the CallbackHandler* and never takes
|
||||
* ownership.
|
||||
* In particular, this means that the CallbackHandler instance must stay valid until all
|
||||
* pending callbacks are been dispatched.
|
||||
*
|
||||
* Similarly, when shutting down filament, care must be taken to ensure that all pending callbacks
|
||||
* that might access filament's state have been dispatched. Filament can no longer ensure this
|
||||
* because callback execution is the responsibility of the CallbackHandler, which is external to
|
||||
* filament.
|
||||
* Typically, the concrete CallbackHandler would have a mechanism to drain and/or wait for all
|
||||
* callbacks to be processed.

|

* A PresentCallable is a callable object that, when called, schedules a frame for presentation on
|
||||
* a SwapChain.
|
||||
*
|
||||
* Typically, Filament's backend is responsible scheduling a frame's presentation. However, there
|
||||
* are certain cases where the application might want to control when a frame is scheduled for
|
||||
* presentation.
|
||||
*
|
||||
* For example, on iOS, UIKit elements can be synchronized to 3D content by scheduling a present
|
||||
* within a CATransation:
|
||||
*
|
||||
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
* void myFrameScheduledCallback(PresentCallable presentCallable, void* user) {
|
||||
* [CATransaction begin];
|
||||
* // Update other UI elements...
|
||||
* presentCallable();
|
||||
* [CATransaction commit];
|
||||
* }
|
||||
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
*
|
||||
* To obtain a PresentCallable, set a SwapChain::FrameScheduledCallback on a SwapChain with the
|
||||
* SwapChain::setFrameScheduledCallback method. The callback is called with a PresentCallable object
|
||||
* and optional user data:
|
||||
*
|
||||
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
* swapChain->setFrameScheduledCallback(myFrameScheduledCallback, nullptr);
|
||||
* if (renderer->beginFrame(swapChain)) {
|
||||
* renderer->render(view);
|
||||
* renderer->endFrame();
|
||||
* }
|
||||
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
*
|
||||
* @remark Only Filament's Metal backend supports PresentCallables and frame callbacks. Other
|
||||
* backends ignore the callback (which will never be called) and proceed normally.
|
||||
*
|
||||
* @remark The SwapChain::FrameScheduledCallback is called on an arbitrary thread.
|
||||
*
|
||||
* Applications *must* call each PresentCallable they receive. Each PresentCallable represents a
|
||||
* frame that is waiting to be presented. If an application fails to call a PresentCallable, a
|
||||
* memory leak could occur. To "cancel" the presentation of a frame, pass false to the
|
||||
* PresentCallable, which will cancel the presentation of the frame and release associated memory.
|
||||
*
|
||||
* @see Renderer, SwapChain::setFrameScheduledCallback

* Camera represents the eye(s) through which the scene is viewed.
|

*
|

* For stereoscopic rendering, a Camera maintains two separate "eyes": Eye 0 and Eye 1. These are
|

* arbitrary and don't necessarily need to correspond to "left" and "right".
|
||||
*
|
||||
* Creation and destruction
|
||||
* ========================
|
||||
*
|
||||
* In Filament, Camera is a component that must be associated with an entity. To do so,
|
||||
* use Engine::createCamera(Entity). A Camera component is destroyed using
|
||||
* Engine::destroyCameraComponent(Entity).

* filament::Engine* engine = filament::Engine::create();
|
||||
*
|
||||

* myCamera->lookAt({0, 1.60, 1}, {0, 0, 0});
|
||||
* engine->destroyCameraComponent(myCamera);
|
||||
* ~~~~~~~~~~~
|
||||
*
|
||||
*
|
||||
* Coordinate system
|
||||
* =================
|
||||
*
|
||||
* The camera coordinate system defines the *view space*. The camera points towards its -z axis
|
||||
* and is oriented such that its top side is in the direction of +y, and its right side in the
|
||||
* direction of +x.
|
||||
*
|
||||
* @note
|
||||
* Since the *near* and *far* planes are defined by the distance from the camera,
|
||||
* their respective coordinates are -\p distance(near) and -\p distance(far).
|
||||
*
|
||||
* Clipping planes
|
||||
* ===============
|
||||
*
|
||||
* The camera defines six *clipping planes* which together create a *clipping volume*. The
|
||||
* geometry outside this volume is clipped.
|
||||
*
|
||||
* The clipping volume can either be a box or a frustum depending on which projection is used,
|
||||
* respectively Projection.ORTHO or Projection.PERSPECTIVE. The six planes are specified either
|
||||
* directly or indirectly using setProjection().
|
||||
*
|
||||
* The six planes are:
|
||||
* - left
|
||||
* - right
|
||||
* - bottom
|
||||
* - top
|
||||
* - near
|
||||
* - far
|
||||
*
|
||||
* @note
|
||||
* To increase the depth-buffer precision, the *far* clipping plane is always assumed to be at
|
||||
* infinity for rendering. That is, it is not used to clip geometry during rendering.
|
||||
* However, it is used during the culling phase (objects entirely behind the *far*
|
||||
* plane are culled).
|
||||
*
|
||||
*
|
||||
* Choosing the *near* plane distance
|
||||
* ==================================
|
||||
*
|
||||
* The *near* plane distance greatly affects the depth-buffer resolution.
|
||||
*
|
||||
* Example: Precision at 1m, 10m, 100m and 1Km for various near distances assuming a 32-bit float
|
||||
* depth-buffer:
|
||||
*
|
||||
* near (m) | 1 m | 10 m | 100 m | 1 Km
|
||||
* -----------:|:------:|:-------:|:--------:|:--------:
|
||||
* 0.001 | 7.2e-5 | 0.0043 | 0.4624 | 48.58
|
||||
* 0.01 | 6.9e-6 | 0.0001 | 0.0430 | 4.62
|
||||
* 0.1 | 3.6e-7 | 7.0e-5 | 0.0072 | 0.43
|
||||
* 1.0 | 0 | 3.8e-6 | 0.0007 | 0.07
|
||||
*
|
||||
* As can be seen in the table above, the depth-buffer precision drops rapidly with the
|
||||
* distance to the camera.
|
||||
*
|
||||
* Make sure to pick the highest *near* plane distance possible.
|
||||
*
|
||||
* On Vulkan and Metal platforms (or OpenGL platforms supporting either EXT_clip_control or
|
||||
* ARB_clip_control extensions), the depth-buffer precision is much less dependent on the *near*
|
||||
* plane value:
|
||||
*
|
||||
* near (m) | 1 m | 10 m | 100 m | 1 Km
|
||||
* -----------:|:------:|:-------:|:--------:|:--------:
|
||||
* 0.001 | 1.2e-7 | 9.5e-7 | 7.6e-6 | 6.1e-5
|
||||
* 0.01 | 1.2e-7 | 9.5e-7 | 7.6e-6 | 6.1e-5
|
||||
* 0.1 | 5.9e-8 | 9.5e-7 | 1.5e-5 | 1.2e-4
|
||||
* 1.0 | 0 | 9.5e-7 | 7.6e-6 | 1.8e-4
|
||||
*
|
||||
*
|
||||
* Choosing the *far* plane distance
|
||||
* =================================
|
||||
*
|
||||
* The far plane distance is always set internally to infinity for rendering, however it is used for
|
||||
* culling and shadowing calculations. It is important to keep a reasonable ratio between
|
||||
* the near and far plane distances. Typically a ratio in the range 1:100 to 1:100000 is
|
||||
* commanded. Larger values may causes rendering artifacts or trigger assertions in debug builds.
|
||||
*
|
||||
*
|
||||
* Exposure
|
||||
* ========
|
||||
*
|
||||
* The Camera is also used to set the scene's exposure, just like with a real camera. The lights
|
||||
* intensity and the Camera exposure interact to produce the final scene's brightness.
|
||||
*
|
||||
*
|
||||
* Stereoscopic rendering
|
||||
* ======================
|
||||
*
|
||||
* The Camera's transform (as set by setModelMatrix or via TransformManager) defines a "head" space,
|
||||
* which typically corresponds to the location of the viewer's head. Each eye's transform is set
|
||||
* relative to this head space by setEyeModelMatrix.
|
||||
*
|
||||
* Each eye also maintains its own projection matrix. These can be set with setCustomEyeProjection.
|
||||
* Care must be taken to correctly set the projectionForCulling matrix, as well as its corresponding
|
||||
* near and far values. The projectionForCulling matrix must define a frustum (in head space) that
|
||||
* bounds the frustums of both eyes. Alternatively, culling may be disabled with
|
||||
* View::setFrustumCullingEnabled.
|
||||
*
|
||||
* \see Frustum, View
