Recolorable Posterization of Volumetric Radiance Fields Using Visibility-Weighted Palette Extraction

COMPUTER GRAPHICS FORUM 2022年第4期41卷 149-160页

作者： Tojo, Kenji Umetani, Nobuyuki Univ Tokyo Tokyo Japan

Volumetric radiance fields have recently gained significant attention as promising representations of photorealistic scene reconstruction. However, the non-photorealistic rendering of such a representation has barely been explored. In this study, we investigate the artistic posterization of the volumetric radiance fields. We extend the recent palette-based image-editing framework, which naturally introduces intuitive color manipulation of the posterized results, into the radiance field. Our major challenge is applying stylization effects coherently across different views. Based on the observation that computing a palette frame-by-frame can produce flickering, we propose pre-computing a single palette from the volumetric radiance field covering its entire visible color. We present a method based on volumetric visibility to sample visible colors from the radiance field while avoiding occluded and noisy regions. We demonstrate our workflow by applying it to pre-trained volumetric radiance fields with various stylization effects. We also show that our approach can produce more coherent and robust stylization effects than baseline methods that compute a palette on each rendered view.

Global Illumination-Aware Stylised Shading

引用

COMPUTER GRAPHICS FORUM 2021年第7期40卷 11-20页

作者： Doi, K. Morimoto, Y. Tsuruno, R.

Our aim is to convert an object's appearance to an arbitrary colour considering the light scattering in the entire scene, which is often called the global illumination. Existing stylisation methods convert the colour of an object with a 1-dimensional texture for 3-dimensional computer graphics to reproduce a typical style used in illustrations and cel animations. However, they cannot express global illumination effects. We propose two individual methods to compute the global illumination and convert the shading to an arbitrary colour. The methods reproduce reflections in other objects with the converted colour. As a result, we can convert the colour of illumination effects that have not yet been reproduced, such as soft shadows and refractions.

Fluidymation: Stylizing Animations Using Natural Dynamics of Artistic Media

引用

COMPUTER GRAPHICS FORUM 2021年第7期40卷 21-32页

We present Fluidymation-a new example-based approach to stylizing animation that employs the natural dynamics of artistic media to convey a prescribed motion. In contrast to previous stylization techniques that transfer the hand-painted appearance of a static style exemplar and then try to enforce temporal coherence, we use moving exemplars that capture the artistic medium's inherent dynamic properties, and transfer both movement and appearance to reproduce natural-looking transitions between individual animation frames. Our approach can synthetically generate stylized sequences that look as if actual paint is diffusing across a canvas in the direction and speed of the target motion.
