US Patent 11989807 Rendering scalable raster content

Embodiments of provide systems, methods, and computer storage media for scaling raster content using pre-computed scalar fields, such as images or textures. In an example implementation, an initial raster image is processed to generate a representation of three scalar fields: an unsigned distance field, an adjacency field, and a color plane (also called a color field or a color texture). These three fields are pre-computed prior to scaling (e.g., outside of a rendering loop), and then subsequently used (e.g., by a GPU as textures) to render a scaled version of the initial raster image.
