PERSPECTIVE CORRECT VECTOR GRAPHICS RENDERING TECHNIQUES

Abstract:

Various implementations disclosed herein include devices, systems, and methods that render perspective correct 2D graphics (e.g., virtual objects, text, graphics) correctly at any angle and distance in an electronic device such as an HMD. In some implementations, a vector graphic including portions defined on a 2D canvas is obtained and the 2D canvas is divided into separate regions, each region containing a plurality of pixels. In some implementations, data based on associating a plurality of the regions of the 2D canvas with the portions of the vector graphic is generated, the data identifying one or more contributing portions of the portions of the vector graphic to use in rendering the pixels in each of the plurality of regions of the 2D canvas. In some implementations, the data is provided to a processor for rendering the vector graphic.
