Autor: Hirokazu Sakai, Kosuke Nabata, Shinya Yasuaki, Kei Iwasaki
Publikováno v: Computational Visual Media, Vol 5, Iss 2, Pp 151-160 (2019)
Abstract In many-light rendering, a variety of visual and illumination effects, including anti-aliasing, depth of field, volumetric scattering, and subsurface scattering, are combined to create a number of virtual point lights (VPLs). This is done in

Visual simulation of clouds
Autor: Yoshinori Dobashi, Kei Iwasaki, Yonghao Yue, Tomoyuki Nishita
Publikováno v: Visual Informatics, Vol 1, Iss 1, Pp 1-8 (2017)
Clouds play an important role when synthesizing realistic images of outdoor scenes. The realistic display of clouds is therefore one of the important research topics in computer graphics. In order to display realistic clouds, we need methods for mode

Adaptive Irradiance Sampling for Many-Light Rendering of Subsurface Scattering
Autor: Kosuke Nabata, Kei Iwasaki
Publikováno v: IEEE Transactions on Visualization and Computer Graphics. 28:3324-3335
Rendering a translucent material involves integrating the product of the transmittance-weighted irradiance and the BSSRDF over the surface of it. In previous methods, this spatial integral was computed by creating a dense distribution of discrete poi

Binary space partitioning visibility tree for polygonal and environment light rendering
Autor: Kei Iwasaki, Hiroki Okuno
Publikováno v: The Visual Computer. 37:2499-2511
In this paper, we present a geometric approach to render shadows for physically based materials under polygonal light sources. Direct illumination calculation from a polygonal light source involves the triple product integral of the lighting, the bid

Temporal and spatial anti-aliasing for rendering reflections on water waves
Autor: Yoshinori Dobashi, Nelson Max, Kei Iwasaki, Namo Podee
Publikováno v: Computational Visual Media. 7(2):201-215
The reflection of a bright light source on a dynamic surface such as water with waves can be difficult to render well in real time due to reflection aliasing and flickering. In this paper, we propose a solution to this problem by approximating the re
