Modern rendering systems are confronted with a dauntingly large and growing set of
requirements: in their pursuit of realism, physically based techniques must increasingly …

DR. JIT is a new just-in-time compiler for physically based rendering and its derivative. DR.
JIT expedites research on these topics in two ways: first, it traces high-level simulation code …

Ray tracing is an inherent part of photorealistic image synthesis algorithms. The problem of
ray tracing is to find the nearest intersection with a given ray and scene. Although this …

The advancements in hardware have drawn more attention than ever to high-quality offline
rendering with modern stream processors, both in the industry and in research fields …

Subsurface scattering, in which light refracts into a translucent material to interact with its
interior, is the dominant mode of light transport in many types of organic materials …

Unbiased rendering of general, heterogeneous participating media currently requires using
null-collision approaches for estimating transmittance and generating free-flight distances. A …

Efficient scene representations are essential for many computer graphics applications. A
general unified representation that can handle both surfaces and volumes simultaneously …

Displacement map** and shell map** add fine-scale geometric features to meshes and
can significantly enhance the realism of an object's surface representation. Both methods …

This article presents a solution to path tracing of massive scenes on multiple GPUs. Our
approach analyzes the memory access pattern of a path tracer and defines how the scene …

Path guiding is a promising tool to improve the performance of path tracing algorithms.
However, not much research has investigated what target densities a guiding method …
