Embodiment Construction

[0020] As mentioned above, in CG animation, a much more robust solution is needed to the problem of creating artistically-looking hand-drawn line work. Additionally, the already created linework needs to be glued, adjusted (if necessary) and incorporated into the existing CG animation. Certain implementations of the present disclosure provide for simulating line art in CG animation. After reading these descriptions it will become apparent how to implement the disclosure in various implementations and applications. Although various implementations of the disclosure will be described herein, it is understood that these implementations are presented by way of example only, and not limitation. As such, this detailed description of various implementations should not be construed to limit the scope or breadth of this disclosure.

[0021] In one implementation, an enhanced ink line application with two modes for generating realistic hand drawn ink line sets is implemented. The fir...

Abstract

Emulation of artistic hand-drawn lines in CG animation includes: first attaching ink lines drawn directly onto characters of the CG animation; first enabling the artist to modify the ink lines using nudges to generate a drawing; first moving the drawing into a UV space and generating first pass training data; second attaching the ink lines onto the characters of the CG animation; second enabling the artist to modify the ink lines; second moving the drawing into the UV space and generating second pass training data; combining the first pass training data and the second pass training data to generate combined data; and creating and outputting a second generation machine learning using the combined data.

Description

[0001] Cross References to Related Applications [0002] This application is required under 35 U.S.C § 119(e) of co-pending U.S. Provisional Patent Application Serial No. 62 / 775843, filed December 5, 2018, entitled "Ink Lines and Machine Learning for Simulating Hand-Drawn Lines" priority rights. The disclosures of the applications cited above are incorporated herein by reference. technical field [0003] This disclosure relates to CG animation, and more particularly, to simulating artistic hand-drawn lines in CG animation. Background technique [0004] In computer graphics (CG) animation, the goal may include creating rendered characters that provide the feel and look of hand-drawn characters. It has been determined that a "line work / ink line" approach involving procedurally based "rules" (eg, using a toon shader) is ineffective at obtaining satisfactory results. The main problem is that artists don't paint based on a limited set of rules. A much more robust solution is ...
