چکیده

As opposed to Monte Carlo integration the quasi-Monte Carlo method does not allow for an error estimate from the samples used for the integral approximation and the deterministic error bound is not accessible in the setting of computer graphics, since usually the integrands are of unbounded variation. We investigate the application of randomized quasi-Monte Carlo integration to bidirectional path tracing yielding much more efficient algorithms that exploit low-discrepancy sampling and at the same time allow for variance estimation.

Quasi-Monte Carlo Global Light Tracing with Infinite Number of Rays

The paper presents an efficient method to solve the general rendering equation, using a combined finite element and quasi-random walk approach. Applying finite element techniques, the surfaces are decomposed into planar patches that are assumed to have position independent, but not direction independent (that is non-diffuse) radiance. The direction dependent radiance function is then computed b...

Quasi-Monte Carlo simulation of the light environment of plants

The distribution of light in the canopy is a major factor regulating the growth and development of a plant. The main variables of interest are the amount of photosynthetically active radiation (PAR) reachingdifferent elements of the plant canopy, and the quality (spectral composition) of light reaching these elements. A light environment model based onMonte Carlo (MC) path tracing of photons, c...

Interactive Global Illumination using Fast Ray Tracing

Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield high quality renderings but are far too slow for interactive use. We present a new parallel global illumination algorithm that perfectly scales, has minimal preprocessing and com...

Non-Local Image Reconstruction for Efficient Computation of Synthetic Bidirectional Texture Functions

Visual prototyping of materials is relevant for many computer graphics applications. A large amount of modeling flexibility can be obtained by directly rendering micro-geometry. While this is possible in principle, it is usually computationally expensive. Recently, bidirectional texture functions (BTFs) have become popular for efficient photo-realistic rendering of surfaces. We propose an effic...
