XRViewport: y property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The read-only XRViewport interface's
y property indicates the offset from the bottom edge of
the destination surface (typically a XRWebGLLayer) to the bottom edge of
the viewport within the surface into which WebXR content is to be rendered. The
viewport's x property identifies the x
component of the origin, and its is given by the width
and height properties.
Value
The offset from the bottom edge of the rendering surface to the bottom edge of the viewport, in pixels.
Note: Although other web APIs typically consider the y
axis to begin at the top and grow larger progressing downward, WebGL reverses this,
with y growing larger as it goes upward on the screen.
Examples
See the main XRViewport page for examples.
