这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

VREyeParameters 接口在 WebVR API represents all the information required to correctly render a scene for a given eye, including field of view information.

This interface is accessible through the VRDisplay.getEyeParameters() 方法。

The values in this interface should not be used to compute view or projection matrices. In order to ensure the widest possible hardware compatibility use the matrices provided by VRFrameData .

特性

VREyeParameters.offset 只读

Represents the o ffset from the center point between the user's eyes to the center of the eye, measured in meters.

VREyeParameters.fieldOfView 只读

Describes t he current field of view for the eye, which can vary as the user adjusts their interpupillary distance (IPD).

VREyeParameters.renderWidth 只读

Describes the recommended render target width of each eye viewport, in pixels.

VREyeParameters.renderHeight 只读

Describes the recommended render target height of each eye viewport, in pixels.

范例

navigator.getVRDisplays().then(function(displays) {
  // If a display is available, use it to present the scene
  vrDisplay = displays[0];
  console.log('Display found');
  // Starting the presentation when the button is clicked:
  //   It can only be called in response to a user gesture
  btn.addEventListener('click', function() {
    vrDisplay.requestPresent([{ source: canvas }]).then(function() {
      console.log('Presenting to WebVR display');
      // Set the canvas size to the size of the vrDisplay viewport
      var leftEye = vrDisplay.getEyeParameters('left');
      var rightEye = vrDisplay.getEyeParameters('right');
      canvas.width = Math.max(leftEye.renderWidth, rightEye.renderWidth) * 2;
      canvas.height = Math.max(leftEye.renderHeight, rightEye.renderHeight);
      drawVRScene();
    });
  });
});
