XREquirectLayer: lowerVerticalAngle property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The lowerVerticalAngle property of the XREquirectLayer interface represents the lower vertical angle in radians for the sphere.

Value

A number representing the lower vertical angle in radians for the sphere. Setting lowerVerticalAngle to a value less than -π/2 will set it to -π/2 and setting it to a value higher than π/2 will set it to π/2.

Examples

Getting a layer's lower vertical angle

The XRWebGLBinding.createEquirectLayer() method creates an equirect layer and allows specifying a lowerVerticalAngle. The XREquirectLayer.lowerVerticalAngle property can be used after layer creation to get the lower vertical angle used or to set it to a new one.

js
const equirectLayer = xrGlBinding.createEquirectLayer({
  space: xrReferenceSpace,
  viewPixelWidth: 1200,
  viewPixelHeight: 600,
  centralHorizontalAngle: 2 * Math.PI,
  upperVerticalAngle: Math.PI / 2.0,
  lowerVerticalAngle: -Math.PI / 2.0,
  radius: 0,
});

equirectLayer.lowerVerticalAngle; // -1.5707963267948966
