Abstract
In one embodiment, a computing system may determine a pixel area in a display coordinate system and project it into a three-dimensional coordinate system to determine a projected area. Based on the projected area, the system may determine a portion of a data structure that contains an analytical definition of a glyph in a two-dimensional coordinate system. The system may access a portion of the analytical definition associated with the selected portion of the data structure, the portion of the analytical definition defining one or more areas of the glyph. The system may project the portion of the analytical definition into the display coordinate system and compute a coverage proportion of the pixel area that overlaps with one or more areas defined by the projected portion of the analytical definition. Based on the coverage, the system may determine a color for the pixel and render the glyph.
