High-Performance Rendering of Realistic Cumulus Clouds Using Pre-computed Lighting
(The Eurographics Association, 2014)
We present a new method for rendering realistic cumulus clouds in real time. The clouds in our approach consist of randomly rotated and scaled copies of a single reference particle. During the pre-processing, we pre-compute ...
Layered Reflective Shadow Maps for Voxel-based Indirect Illumination
(The Eurographics Association, 2014)
We introduce a novel voxel-based algorithm that interactively simulates both diffuse and glossy single-bounce indirect illumination. Our algorithm generates high quality images similar to the reference solution while using ...
Reduced Precision for Hardware Ray Tracing in GPUs
(The Eurographics Association, 2014)
We propose a high performance, GPU integrated, hardware ray tracing system. We present and make use of a new analysis of ray traversal in axis aligned bounding volume hierarchies. This analysis enables compact traversal ...
Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur
(The Eurographics Association, 2014)
Hair and fur typically consist of a large number of thin, curved, and densely packed strands which are difficult to ray trace efficiently. A tight fitting spatial data structure, such as a bounding volume hierarchy (BVH), ...
Filtering Distributions of Normals for Shading Antialiasing
(The Eurographics Association, 2016)
High-frequency illumination effects, such as highly glossy highlights on curved surfaces, are challenging to render in a stable manner. Such features can be much smaller than the area of a pixel and carry a high amount of ...
Adaptive Sampling for On-The-Fly Ray Casting of Particle-based Fluids
(The Eurographics Association, 2016)
We present a fast and accurate ray casting technique for unstructured and dynamic particle sets. Our technique focuses on efficient, high quality volume rendering of fluids for computer animation and scientific applications. ...
Local Shading Coherence Extraction for SIMD-Efficient Path Tracing on CPUs
(The Eurographics Association, 2016)
Accelerating ray traversal on data-parallel hardware architectures has received widespread attention over the last few years, but much less research has focused on efficient shading for ray tracing. This is unfortunate ...
Lightcut Interpolation
(The Eurographics Association, 2016)
Many-light rendering methods replace multi-bounce light transport with direct lighting from many virtual point light sources to allow for simple and efficient computation of global illumination. Lightcuts build a hierarchy ...
GVDB: Raytracing Sparse Voxel Database Structures on the GPU
(The Eurographics Association, 2016)
Simulation and rendering of sparse volumetric data have different constraints and solutions depending on the application area. Generating precise simulations and understanding very large data are problems in scientific ...
Real-Time Diffuse Global Illumination Using Radiance Hints
(ACM, 2011)
GPU-based interactive global illumination techniques are receiving an increasing interest from both the research and the industrial community as real-time graphics applications strive for vi-sually rich and realistic dynamic ...
