1. A method, comprising:
determining spatial relationships between a wearable device and a three-dimensional (3D) space using light rays from two or more light sources installed at the wearable device, wherein the light rays include first light rays of a first light wavelength from a first light source of the two or more light sources; wherein the light rays further include second light rays of a second light wavelength, different from the first light wavelength, from a second different light source of the two or more light sources;
performing, based at least in part on the spatial relationships between the wearable device and the 3D space, spatial transformations on image content of display images to generate transformed display images;
causing the transformed device display images to be rendered on an image display of the wearable device.
