XRViewport.y
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.
Syntax
y = xrViewport.y;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.
