We introduce a novel transmittance model to improve the volumetric representation of 3D
scenes. The model can represent opaque surfaces in the volumetric light transport …

Participating media are frequent in real-world scenes, whether they contain milk, fruit juice,
oil, or muddy water in a river or the ocean. Incoming light interacts with these participating …

The complex interplay of a number of physical and meteorological phenomena makes
simulating clouds a challenging and open research problem. We explore a physically …

Physically based rendering of complex scenes can be prohibitively costly with a potentially
unbounded and uneven distribution of complexity across the rendered image. The goal of …

When lifting the assumption of spatially-independent scattering centers in classical linear
transport theory, collision rate is no longer proportional to angular flux/radiance because the …

We consider the scattering of light in participating media composed of sparsely and
randomly distributed discrete particles. The particle size is expected to range from the scale …

We investigate the parameter estimation problem for a diagonalizable stochastic evolution
equation driven by an additive noise that is white in space and fractional in time. The …

The mixed model with polynomial drift of the form $ X (t)=\theta\mathcal {P}(t)+\alpha W
(t)+\sigma {B_ {H}^{n}}(t) $ is studied, where ${B_ {H}^{n}} $ is the nth-order fractional …

Many real-world materials such as sand, snow, salt, and rice are comprised of large
collections of grains. Previously, multiscale rendering of granular materials requires …

There is a great demand for visualizing natural atmospheric clouds in a realtime
environment. However, the challenge is maintaining the cloud visualization system …
