Based in Montreal since 2015, ON produced and created the pipeline for Mune: Guardian of the Galaxy and The Little Prince, still the most successful French animated movie in the world, and Playmobil The Movie
ON is currently working on Ladybug & Cat Noir Awakening based on the mega-hit series, Miraculous Ladybug, and continuing to expand its compelling portfolio of engaging and unique blockbusters.
In this paper, we describe a technique called Shape Analysis Driven Surface Correction that introduces a new generalized way of stor- ing and restituting surface corrections and automate their blending by using live surface shape analysis combined with Radial Basis Function (RBF) based interpolators.
In this paper, we present the solution we developped at ON Animation Studios to assist the Character FX department on the production of Mune and The Little Prince. Our goal was to design a tool that adapts to the artists rather than a solution that requires learning and practice. To do this, we provide the grooming artists the freedom to choose the interaction mode they feel the most comfortable with. Therefore, the grooming system we wrote provides three different approaches to create hair: curve sculpting, volume modeling, and sketch-based. While being different, these approaches remains compatible and can be mixed together depending of the artists’ needs.
We present a new storage scheme for computer graphic images based on OpenEXR 2.Using such EXR/Id files, the compositing artist can isolate an object selection (by picking them or using a regular expression to match their names) and color corrects them with no edge artefact, which was not possible to achieve without rendering the object selection on its own layer. Using this file format avoids going back and forth between the rendering and the compositing departments because no mask image or layering are needed anymore.
The technique is demonstrated in an open source software suite, including a library to read and write the EXR/Id files and an OpenFX plug-in which generates the images in any compositing software.
