Toulouse de MargerieJune 3, This post will discuss how Unity natively maintains frame rates and how user code can be added to tightly control it. This can be vital in an environment like a broadcast studio where synchronization between Unity and other equipment is crucial. Normally, out of the box, a Unity project will attempt to run your project as fast as possible. The simplest way to start controlling frame rate is to explicitly set the QualitySettings. This may not give granular enough control, however, as you are limited to submultiples of the display refresh rate. The next simplest solution would be to set QualitySettings. With this set, Unity will throttle back its rendering loop to approximately this rate note that tearing may occur since Unity will no longer be rendering in sync with the display. This is done in a low-cost manner so as not to unnecessarily burn CPU resources. The downside is that this approach may not yield the required precision for every use case. Fear not, coroutines can help improve precision. In order to do so, you must let Unity try to run as fast as possible by setting QualitySettings. To do this precisely, we suggest you use a combination of Thread. Sleep to conservatively delay the Unity rendering loop without eating up CPU resources, and then for the last few milliseconds, spin the CPU while checking for exactly the right time to allow the next frame to start. This is can be achieved by setting Time. As of Unity For older Unity versions, if your external signal is not operating at an integer based rate like say A sample proof-of-concept Unity project exploring the above topic is available at our GitHub project page. A more complex example which emulates an external genlock can be found in GenLockedRecorder. Although Unity does not natively support any vendor-specific genock implementation, the latter is a good starting point for integration with a third-party SDK offering this feature. Please note that all above techniques yield the most stable frame rates when part of a Unity standalone player build. They are functional nonetheless when in Play Mode inside the Unity Editor but you may experience momentary fluctuations from time to time. Seriously, whenever precise timing measures are needed, Stopwatch is the way to go. Unity has a serious problem with the method used for calculating Time.

It also collects configuration metadata, such as build and player settings, which is useful when comparing data against different hardware and configurations. For more information on how to create and run tests please refer to Unity Test Runner documentation. Important Note: When tests are run with the Unity Test Runner, a development player is always built to support communication between the editor and player, effectively overriding the development build setting from the build settings UI or scripting API. To access performance testing apis add Unity. PerformanceTesting to your assembly definition references section. It will initialize necessary test setup for performance tests. This type of test starts and ends within the same frame. This is a good choice if you want to sample measurements across multiple frames. If not specified it will be assumed to be 1. This is essential when comparing results as we results will vary anytime the test changes. The Performance Testing Extension provides several API methods you can use to take measurements in your performance test, depending on what you need to measure and how you want to do it. In order to use this you have to include using Unity. PerformanceTesting at the top of your script. Measures execution time for the scope as a single time, for both synchronous and coroutine methods. Used to record profiler markers. Profiler marker timings will be pciked up automatically and sampled within the scope of the using statement. Name of the SampleGroupDefinition should match profiler marker name. Note that deep and editor profiling are not available. Profiler markers created using Profiler. BeginSample are not supported, switch to ProfilerMarker if possible. When you want to record samples outside of frame time, method time, or profiler markers, use a custom measurement. It can be any double value. A sample group definition is required. When a test is selected in the Unity Test Runner window within the Unity Editor, each performance test will have a performance test summary. Time Millisecond Median The Performance Test Report window shows a detailed breakdown of individual test runs.

Time and Framerate Management

HoloLens includes a world-facing camera mounted on the front of the device, which enables apps to see what the user sees. Developers have access to and control of the camera, just as they would for color cameras on smartphones, portables, or desktops. The same universal windows media capture and windows media foundation APIs that work on mobile and desktop work on HoloLens. Unity has also wrapped these windows APIs to abstract simple usage of the camera on HoloLens for tasks such as taking regular photos and videos with or without holograms and locating the camera's position in and perspective on the scene. The camera supports the following modes all modes are aspect ratio at 30, 24, 20, 15, and 5 fps:. HoloLens 2 supports different camera profiles. Learn how to discover and select camera capabilities. The camera supports the following profiles and resolutions all video modes are aspect ratio :. Customers can leverage mixed reality capture to take videos or photos of your app, which include holograms and video stabilization. As a developer, there are considerations you should take into account when creating your app if you want it to look as good as possible when a customer captures content. You can also enable and customize mixed reality capture from directly within your app. Learn more at mixed reality capture for developers. When HoloLens takes photos and videos, the captured frames include the location of the camera in the world, as well as the lens model of the camera. This allows applications to reason about the position of the camera in the real world for augmented imaging scenarios. Developers can creatively roll their own scenarios using their favorite image processing or custom computer vision libraries. Unless denoted otherwise, "camera" on this page refers to the real-world RGB color camera. Refer to the Holographic face tracking sample for more information. Each image frame whether photo or video includes a SpatialCoordinateSystem rooted at the camera at the time of capture, which can be accessed using the CoordinateSystem property of your MediaFrameReference. In addition, each frame contains a description of the camera lens model, which can be found in the CameraIntrinsics property. Together, these transforms define for each pixel a ray in 3D space representing the path taken by the photons that produced the pixel. These rays can be related to other content in the app by obtaining the transform from the frame's coordinate system to some other coordinate system e. To summarize, each image frame provides the following:. Locatable camera in DirectX : The Holographic Face Tracking sample shows the fairly straightforward way to query for the transform between the camera's coordinate system and your own application coordinate system s. On HoloLens, the video and still image streams are undistorted in the system's image processing pipeline before the frames are made available to the application the preview stream contains the original distorted frames. Because only the CameraIntrinsics are made available, applications must assume image frames represent a perfect pinhole camera. On HoloLens first-generationthe undistortion function in the image processor may still leave an error of up to 10 pixels when using the CameraIntrinsics in the frame metadata. The Device Camera frames come with a "Camera To World" transform, that can be used to show exactly where the device was when the image was taken. For example, you could position a small holographic icon at this location CameraToWorld. MultiplyPoint Vector3. MultiplyVector Vector3. Many mixed reality applications use a recognizable image or visual pattern to create a trackable point in space. This is then used to render objects relative to that point or create a known location. Some uses for HoloLens include finding a real world object tagged with fiducials e. To recognize a visual pattern, and then place that object in the applications world space, you'll need a few things:. Keeping an interactive application frame-rate is critical, especially when dealing with long-running image recognition algorithms. For this reason, we commonly use the following pattern:. Some image marker systems only provide a single pixel location others provide the full transform in which case this section will not be neededwhich equates to a ray of possible locations.
