Conservative Ray Batching using Geometry Proxies
(The Eurographics Association, 2020)
We present a method for improving batched ray traversal as was presented by Pharr et al. [PKGH97]. We propose to use conservative proxy geometry to more accurately determine whether a ray has a possibility of hitting any ...
A Multi-pass Method for Accelerated Spectral Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Spectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with ...
Next Event Estimation++: Visibility Mapping for Efficient Light Transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Monte-Carlo rendering requires determining the visibility between scene points as the most common and compute intense operation to establish paths between camera and light source. Unfortunately, many tests reveal occlusions ...
Interactively Modifying Compressed Sparse Voxel Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Voxels are a popular choice to encode complex geometry. Their regularity makes updates easy and enables random retrieval of values. The main limitation lies in the poor scaling with respect to resolution. Sparse voxel DAGs ...
Pacific Graphics 2020 - CGF 39-7: Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Texture Browser: Feature-based Texture Exploration
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Texture is a key characteristic in the definition of the physical appearance of an object and a crucial element in the creation process of 3D artists. However, retrieving a texture that matches an intended look from an ...
Pacific Graphics 2021 - CGF 40-7: Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Geometric Sample Reweighting for Monte Carlo Integration
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Numerical integration is fundamental in multiple Monte Carlo rendering problems. We present a sample reweighting scheme, including underlying theory, and analysis of numerical performance for the integration of an unknown ...
Directed Acyclic Graph Encoding for Compressed Shadow Maps
(The Eurographics Association, 2021)
Detailed shadows in large-scale environments are challenging. Our approach enables efficient detailed shadow computations for static environments at a low memory cost. It builds upon compressed precomputed multiresolution ...
Targeting Shape and Material in Lighting Design
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Product lighting design is a laborious and time-consuming task. With product illustrations being increasingly rendered, the lighting challenge transferred to the virtual realm. Our approach targets lighting design in the ...
