XRWebGLLayer: framebufferHeight 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.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The read-only XRWebGLLayer
property
framebufferHeight
indicates the height of the
framebuffer, in pixels.
You can get the width of the framebuffer using the
framebufferWidth
property.
Value
The height in pixels of the XR device's framebuffer. Each of the framebuffer's attachments (pixel, depth, color, and/or stencil buffers, for example) are all this many pixels tall.
Examples
This snippet fetches the framebuffer's width and height for later use.
let glLayer = xrSession.renderState.baseLayer;
gl.bindFramebuffer(gl.FRAMEBUFFER, glLayer.framebuffer);
frameWidth = glLayer.framebufferHeight;
frameHeight = glLayer.framebufferHeight;
