Abstract
Disclosed are methods and systems for generating display pixel data so as to reduce latency when rendering a representation of a graphic on a display, such as for augmented-reality applications. The method comprises: receiving a set of display pixel coordinate-pairs at the graphics processing unit; applying a transform matrix to the set of display pixel coordinate-pairs to obtain a set of graphic pixel coordinate-pairs, the transform matrix calculated using orientation data received from an external reference; retrieving a set of graphic pixel data associated with the set of graphic pixel coordinate-pairs; and, determining a set of display pixel data based on the retrieved set of graphic pixel data.
