Unity3D 室内小场景搭建(抓取、抛扔物体；射线相交位置瞬移)

SteamVR plugin for Unity - v1.2.2 Copyright (c) Valve Corporation, All rights reserved. Quickstart: To use, simply add the SteamVR_Camera script to your Camera object(s). Everything else gets set up at runtime. See the included quickstart guide for more details. Requirements: The SteamVR runtime must be installed. This can be found in Steam under Tools. Changes for v1.2.2: * Updated to SteamVR runtime v1497390325 and SDK version 1.0.8. * [General] Switched caching SteamVR_Events.Actions from Awake to constructors to fix hot-loading of scripts in the Editor. * [General] Switched remaining coroutines away from using strings (to avoid issues with obfuscators). * [General] Switched from using deprecated Transform.FindChild to Transform.Find. * [General] Added #if !UNITY_METRO where required to allow compiling for UWP. * [UpdatePoses] Switched to using static delegates (Camera.onPreCull or Application.onBeforeRender depending on version) for updating poses. * [UpdatePoses] Deprecated SteamVR_UpdatePoses component. * [MixedReality] Added rgba settings to externalcamera.cfg for overriding foreground chroma key (default 0,0,0,0). * [MixedReality] Exposed SteamVR_ExternalCamera.Config settings in Unity Editor inspector for easy tweaking. * [MixedReality] Added file watcher to externalcamera.cfg to allow real-time editing. * [MixedReality] Fixed antialiasing complaint in Unity 5.6+. * [MixedReality] Added second pass to foreground camera when using PostProcessingBehaviour since those fx screw up the alpha channel. * [ControllerManager] Added code to protect against double-hiding of controllers. * [InteractionSystem] Sub-objects now inherit layer and tag of spawning object (ControllerButtonHints, ControllerHoverHighlight, Hand, SpawnRenderModel). Changes for v1.2.1: * Updated to SteamVR runtime v1485823399 and SDK version 1.0.6. * Switched SteamVR_Events.SystemAction from using strings to specify event type over to their associated enum values. * Fixed an issue with using WWW in static constructors. * Added Unity Preferences for SteamVR to allow disabling automatic enabling of native OpenVR support in Unity 5.4 or newer. https://github.com/ValveSoftware/steamvr_unity_plugin/issues/8 https://github.com/ValveSoftware/steamvr_unity_plugin/pull/9 * Added UNITY_SHADER_NO_UPGRADE to all shaders to avoid log spam in later versions of Unity for issues that have already been fixed but the compiler isn't able to detect. * Specified Vulkan support for Interaction System shaders. * Fix for crash in Interaction_Example selecting BowPickup: https://github.com/ValveSoftware/steamvr_unity_plugin/issues/4 * Cleaned up unused fields: https://github.com/ValveSoftware/steamvr_unity_plugin/issues/2 * Updated Interaction System's LinearDrive to initialize using linearMapping.value. https://github.com/ValveSoftware/steamvr_unity_plugin/pull/5 * Updated Interaction System documetation to fix a few errors. * Added an icon for all Interaction System scripts. * Fixes for SteamVR on Linux. Changes for v1.2.0: * Updated to SteamVR runtime v1481926580 and SDK version 1.0.5. * Replaced SteamVR_Utils.Event with SteamVR_Events.<EventName> to avoid runtime memory allocation associated with use of params object[] args. * Added SteamVR_Events.<EventName>Action to make it easy to wrap callbacks to avoid memory allocation when components are frequently enabled/disabled at runtime. * Fixed other miscellaneous runtime memory allocation in SteamVR_Render and SteamVR_RenderModels. (Suggestions by unity3d user @8bitgoose.) * Integrated fix for SteamVR_LaserPointer direction (from github user @fredsa). * Integrated fixes and comments for SteamVR_Teleporter (from github user @natewinck). * Removed SteamVR_Status and SteamVR_StatusText as they were using SteamVR_Utils.Event with generic strings which is no longer allowed. * Added SteamVR_Controller.assignAllBeforeIdentified (to allow controller to be assigned before identified as left vs right). Suggested by github user @chrwoizi. * Added SteamVR_Controller.UpdateTargets public interface. This allows spawning the component at runtime. Suggested by github user @demonixis. * Fixed bug with SteamVR_TrackedObject when specifying origin. Suggested by github user @fredsa. * Fixed issue with head camera reference in SteamVR_Camera. Suggested by github user @pedrofe. Known issues: * The current beta version of Unity 5.6 breaks the normal operation of the SteamVR_UpdatePoses component (required for tracked controllers). To work around this in the meantime, you will need to manually add the SteamVR_UpdatePoses component to your main camera. Changes for v1.1.1: * Updated to SteamVR runtime v1467410709 and SDK version 1.0.2. * Updated Copyright notice. * Added SteamVR_TrackedCamera for accessing tracked camera video stream and poses. * Added SteamVR_TestTrackedCamera scene and associated script to demonstrate how to use SteamVR_TrackedCamera. * Fix for SteamVR_Fade shader to account for changes in Unity 5.4. * SteamVR_GameView will now use the compositor's mirror texture to render the companion window (pre-Unity 5.4 only). * Renamed SteamVR_LoadLevel 'externalApp' to 'internalProcess' to reflect actual functionality. * Fixed issue with SteamVR_PlayArea material loading due to changes in Unity 5.4. * Added Screenshot support handling for stereo panoramas generation. * Removed code that was setting Time.maximumDeltaTime as this was causing issues. Changes for v1.1.0: * Fix for error building standalone in SteamVR_LoadLevel. * Set SteamVR_TrackedObject.isValid to false when disabled. Changes for v1.0.9: * Updated to SteamVR runtime v1461626459 and SDK version 0.9.20. * Updated workshop texture used in sea of cubes example level to use web page from SteamVR (was previously from Portal). * Updated various SDK changes to Unity in 5.4 betas. * Added controllerModeState to RenderModel component to control additional features like scrollwheel visibility. * RenderModels now respond to model skin changes. * Removed OnGUI and associated help text (i.e. "You may now put on your headset." notification) as this was causing unnecessary overhead. * Fix to SteamVR_Render not turning back on if all cameras were disabled and then re-enabled. * Hooked up SteamVR_Render.pauseRendering in Unity 5.4 native OpenVR integration. * Fix for input_focus event sometimes getting sent inappropriately. * Fix for timeScale handling. * Fix for SteamVR_PlayArea not finding its material in editor in Unity 5.4 due to changes in how Unity handles asset loading. * Miscellaneous fixes to reduce hitching when using SteamVR_LoadLevel to handle scene transitions. * Hooked up SteamVR_Camera.sceneResolutionScale to Unity 5.4's native vr integration render target scaling. * Forced SteamVR initialization check in SteamVR_Camera.enable (and bail upon failure) in Unity 5.4 (was already doing this in older builds). * Better handling of SteamVR_Ears component with old content. * Keep legacy head object around in case external components were referencing it (was previously getting deleted in Unity 5.4 as the head motion is now applied to the "eyes" object). * Miscellaneous fixes for SteamVR_TrackedController and SteamVR_Teleporter. * Fixed up Extra scenes SteamVR_TestThrow and SteamVR_TestIK. * Added stereo panorama screenshot support to SteamVR_Skybox. * Removed use of deprecated UnityEditorInternal.VR.VREditor.InitializeVRPlayerSettingsForBuildTarget(BuildTargetGroup.Standalone); Changes for v1.0.8: * Updated to SteamVR runtime v1457155403. * Updated to work with native OpenVR integration introduced in Unity 5.4. In this and newer versions, openvr_api.dll will be automatically deleted when launching since it ships as part of Unity now.
