US Patent 9529486 Methods and apparatus for providing a digital illustration system

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor to receive a set of data elements associated with a user-defined content having a content type. The processor interpolates the set of data elements to produce a first set of content data based on a filter domain associated with the user-defined content. The processor further refines the first set of content data based, at least in part, on the content type to produce a second set of content data. The processor also sends a signal representing the second set of content data such that the user-defined content is displayed based on the second set of content data.
