This disclosure describes techniques for modifying application program interface (API) calls in a manner that can cause a device to render native three dimensional (3D) graphics content in stereoscopic 3D. The techniques of this disclosure can be implemented in a manner where API calls themselves are modified, but the API itself and the GPU hardware are not modified. The techniques of the present disclosure include using the same viewing frustum defined by the original content to generate a left-eye image and a right-eye image and shifting the viewport offset of the left-eye image and the right-eye image.

3D to stereoscopic 3D conversion

Aspects of this disclosure are directed to techniques to store values indicative of one or more scissor regions in a scissor buffer. In aspects of this disclosure, a processor may receive two dimensional (2-D) coordinates of a scissor region. The processor may transform the 2-D coordinates into coordinates that include more than two dimensions. The processor may store a value indicative of the scissor region in one or more storage units of the scissor buffer based on the coordinates that include more than two dimensions.

Graphics processing using two-dimensional scissor regions

In a particular illustrative embodiment, a method of determining a viewpoint of a person based on skin color area and face area is disclosed. The method includes receiving image data corresponding to an image captured by a camera, the image including at least one object to be displayed at a device coupled to the camera. The method further includes determining a viewpoint of the person relative to a display of the device coupled to the camera. The viewpoint of the person may be determined by determining a face area of the person based on a determined skin color area of the person and tracking a face location of the person based on the face area. One or more objects displayed at the display may be moved in response to the determined viewpoint of the person.
