XREquirectLayer.upperVerticalAngle
The upperVerticalAngle
property of the XREquirectLayer
interface represents the upper vertical angle in radians for the sphere.
Value
A number representing the upper vertical angle in radians for the sphere. Setting upperVerticalAngle
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 upper vertical angle
The XRWebGLBinding.createEquirectLayer()
method creates an equirect layer and allows specifying a upperVerticalAngle
. The XREquirectLayer.upperVerticalAngle
property can be used after layer creation to get the upper vertical angle used or to set it to a new one.
const equirectLayer = xrGlBinding.createEquirectLayer({
space: xrReferenceSpace,
viewPixelWidth: 1200,
viewPixelHeight: 600,
centralHorizontalAngle: 2 * Math.PI,
upperVerticalAngle: Math.PI / 2.0,
upperVerticalAngle: -Math.PI / 2.0,
radius: 0
});
equirectLayer.upperVerticalAngle; // 1.5707963267948966
