A display system, such as a virtual reality or augmented reality display system, can control a display to present image data including a plurality of color components, on a plurality of depth planes supported by the display. The presentation of the image data through the display can be controlled based on control information that is embedded in the image data, for example to indicate an active or inactive color component and/or depth plane. In some examples, light sources and/or spatial light modulators that relay illumination from the light sources may receive signals from a display controller to adjust a power setting to the light source or spatial light modulator based on control information embedded in an image data frame.

Virtual and augmented reality systems and methods using display system control information embedded in image data

In one embodiment, a method includes a step of receiving a geometric representation of a virtual object and a texture atlas, the geometric representation comprising multiple geometric primitives defining a shape of the virtual object, the texture atlas comprises regions each of which is allocated to include shading information of a respective geometric primitive of the plurality of geometric primitives, and the shading information of the respective geometric primitive being scaled down to be smaller than the allocated region so as to create a buffer between the allocated region and adjacent regions of the plurality of regions on the texture atlas. The method further includes steps of identifying, based on a first viewpoint from which to view the virtual object, visible geometric primitives from the plurality of geometric primitives and rendering images of the visible geometric primitives using corresponding shading information included in the texture atlas.
