Stereoscopic rendering of non-flat, reflective or refractive surfaces
A computer program product may cause one or more processors to generate stereoscopic images of one or more 3D models within a 3D model space. As part of the generation of the stereoscopic images, special case surfaces that are non-flat and specularly reflective or refractive are rendered in a special manner. The special manner involves rendering a texture for the special case surface based on a third projection corresponding to a third viewpoint that is spaced from both a first viewpoint (i.e., a left eye viewpoint) and a second viewpoint (i.e., a right eye viewpoint). Accordingly, when rendering first and second images (i.e., images corresponding respectively to the first and second viewpoints), the texture corresponding to the third viewpoint may be applied to the special case surface in both the first and second images. As a result, the disparity between the stereoscopic images may be low enough that the special case surface may be readily fused by the human viewer and not become a visual problem or an area of unwanted visual focus for the viewer.

A system and method for generating compact light-field displays through varying optical depths provides digital content in a more effective and efficient manner. The system includes a field-evolving cavity with a cavity exit pupil, a relay mechanism, and a system enclosure with an enclosure exit pupil. The field-evolving cavity modifies the light-field displays before outputting the light-field displays with the cavity exit pupil. More specifically, the field-evolving cavity includes at least one display panel, which initially generates the light-field displays, and at least one optical-tuning mechanism, which subsequently modifies the light-field displays to varying optical depths. The system enclosure houses the field-evolving cavity and the relay mechanism. The relay mechanism directs the light-field displays from the cavity exit pupil to the enclosure exit pupil, which outputs the light-field displays to a user.
Bonding methods for light emitting diodes
Disclosed herein are techniques for bonding LED components. According to certain embodiments, a first component including a semiconductor layer stack is hybrid bonded to a second component including a substrate that has a different thermal expansion coefficient than the semiconductor layer stack. The semiconductor layer stack includes an n-side semiconductor layer, an active light emitting layer, and a p-side semiconductor layer. The first component and the second component further include first contacts and second contacts, respectively. To hybrid bond the two components, the first contacts are aligned with the second contacts. Then dielectric bonding is performed to bond respective dielectric materials of both components. The dielectric bonding is followed by metal bonding of the contacts, using annealing. To compensate run-out between the first contacts and the second contacts, aspects of the present disclosure relate to changing a curvature of the first component and/or the second component during the annealing stage.
