XRWebGLSubImage: colorTexture property

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

The read-only colorTexture property of the XRWebGLSubImage interface represents the color WebGLTexture object for the XRCompositionLayer to render.

Value

An opaque WebGLTexture. See WebXR opaque textures for details.

Examples

Using colorTexture

The colorTexture property can be passed to WebGL2RenderingContext.framebufferTextureLayer() to attach the color texture to a framebuffer.

js

const xrGlBinding = new XRWebGLBinding(xrSession, gl);
const layer = xrGlBinding.createProjectionLayer({
  textureType: "texture-array",
});
const framebuffer = gl.createFramebuffer();

xrSession.updateRenderState({ layers: [layer] });
xrSession.requestAnimationFrame(onXRFrame);

function onXRFrame(time, xrFrame) {
  xrSession.requestAnimationFrame(onXRFrame);

  gl.bindFramebuffer(gl.FRAMEBUFFER, framebuffer);
  const viewport = xrGlBinding.getSubImage(layer, xrFrame).viewport;
  gl.viewport(viewport.x, viewport.y, viewport.width, viewport.height);

  for (const view in xrViewerPose.views) {
    const subImage = xrGlBinding.getViewSubImage(layer, view);
    gl.framebufferTextureLayer(
      gl.FRAMEBUFFER,
      gl.COLOR_ATTACHMENT0,
      subImage.colorTexture,
      0,
      subImage.imageIndex,
    );
    gl.framebufferTextureLayer(
      gl.FRAMEBUFFER,
      gl.DEPTH_ATTACHMENT,
      subImage.depthStencilTexture,
      0,
      subImage.imageIndex,
    );

    // Render from the viewpoint of xrView
  }
}
