Thoroughly revised, this third edition focuses on modern techniques used to generate
synthetic three-dimensional images in a fraction of a second. With the advent of …

Despite much progress, creating real-time high-fidelity head avatar is still difficult and
existing methods have to trade-off between speed and quality. 3DMM based methods often …

Recent work has developed analytic formulae for spherical harmonic (SH) coefficients from
uniform polygonal lights, enabling near-field area lights to be included in Precomputed …

Spherical Harmonic (SH) lighting is widely used for real-time rendering within Precomputed
Radiance Transfer (PRT) systems. SH coefficients are precomputed and stored at object …

Microfacet reflectance models are a powerful tool for expressing the behavior of real-world
appearance. Traditionally, these models relied on aggregate statistical formulations of the …

Many applications in rendering rely on integrating functions over spherical polygons. We
present a new numerical solution for computing the integral of spherical harmonics (SH) …

Spherical Harmonics (SH) have been proven as a powerful tool for rendering. As a set of 2D
basis functions, spherical harmonics are able to represent and recover low frequency …

Efficient approximation of incident radiance functions from a set of samples is still an open
problem in physically based rendering. Indeed, most of the computing power required to …

In this paper, we introduce harmonics virtual lights (HVL), to model indirect light sources for
interactive global illumination of dynamic 3D scenes. Virtual point lights (VPL) are an …

Spherical Harmonics (SH) are a convenient basis for representing various signals in
computer graphics, with lighting and visibility being the most common. While the inputs tend …
