Abstract: Implementations generally relate to providing augmented reality in a web browser. In one implementation, a method includes capturing images of a physical scene with a camera of a device. The method further includes determining motion of the camera using six degrees of freedom (6DoF) marker-based tracking. The method further includes determining positions of markers relative to the camera using 6DoF marker-based tracking. The method further includes overlaying virtual content onto a depicted physical scene in the images, resulting in augmented reality (AR) images. The method further includes rendering the AR images in a browser of the device.
