WebVR input utility

About

This package utilize loading, selection gamepads models for current vr device, positioning them relative head.
Typescript ready.

Supported devices:

1. Lenovo DayDream
2. Oculus Rift
3. Oculus Go
4. Oculus Quest
5. Gear VR
6. HTC Vive
7. WinowsMixedReality(WIP)

Installation

1. Install package: npm i vr_controls

2. Include models in your bundle:

   1. If you use webpack, you should copy models directory somewhere in your destination directory.
      It is better to use custom copy plugin, instead of CopyWebpackPlugin, because, the 2nd one has some problems when copying gltf`s .bin file.

      ...
      plugins: [
          ...
          {
              apply: (cmplr) => {
                  cmplr.hooks.afterEmit.tap("MyCopyPlug", (cmpln) => {
                      let from = path.join(__dirname, "node_modules", "vr_controls", "lib", "gamepad");
                      let to = path.join(__dirname, "dist", "models", "gamepad");
      
                      let files = fs.readdirSync(from);
                      for (let i = 0; i < files.length; i++) {
                          fs.copyFileSync(
                              path.join(from, files[i]),
                              path.join(to, files[i]));
                      }
      
                      console.log("custom copy applied");
                  })
              }
          },
          ...
      ]

      In this case, files from gamepad folder will be copied into __dirname/dist/models/gamepad, where dist -- is my destination folder.

Members

1. VRModelsLoader -- Utility for vr models loading and parse them.
2. VRControls -- Gets native gamepads and serialzie its into handy wrappers
3. VRGamepadData -- Handy native gamepad data wrapper, serialize data into three.js types
4. VRManager -- Utility for enter/exit vr events, detect current vr mode, current device detection
5. VRBodyDefault -- basic implementation of vr body, that automatically handle 3dof and 6 dof gamepads. If there is 3dof gamepads -- Body will pose them with virtual arm. If 6dof - will pose them as it is.
6. GamepadModelsNames -- dictionary for gamepads models names.
7. HMDsNames -- dictionary for known head mounted devices.

Usage

You can use package in default and custom way.
In any case, first of all, you should initialize VRManager, and pass the gamepad model path (in dist folder) into VRModelsLoader.

VRManager.Init(YourRenderer);
VRModelsLoader.ModelsGLTFUrl = "models/gamepad";
...

In the example above, this path specified, because webpack will copy models in this(models/gamepad) folder, and my dist looks like this:

Usage examples

1. Example of default way:
   Body will automatically pose gamepads, depends on their DOF.

      
   let body = new VRBodyDefault();
   
   yourUpdateLoop(() => {
       body.UpdateGamepadsData(Renderer.vr.getStandingMatrix());
       body.UpdatePose(MainScene, HeadObject);
   });

   The body.Hands[] contains instances of Object3D, that used as posing points. Gamepads 3d models snaps on them.
   It is safe, to replace them with body.ReplaceHand(...), on your own objects at the run time.
   Hands[0] - left hand; Hands[1] - right hand

2. Custom way:
