Efficient BVH Construction via Approximate Agglomerative Clustering
(ACM, 2013)
We introduce Approximate Agglomerative Clustering (AAC), an efficient, easily parallelizable algorithm for generating high-quality bounding volume hierarchies using agglomerative clustering. The main idea of AAC is to ...
An Energy and Bandwidth Efficient Ray Tracing Architecture
(ACM, 2013)
We propose two hardware mechanisms to decrease energy consumption on massively parallel graphics processors for ray tracing while keeping performance high. First, we use a streaming data model and configure part of the L2 ...
Fast Parallel Construction of High-Quality Bounding Volume Hierarchies
(ACM, 2013)
We propose a new massively parallel algorithm for constructing high-quality bounding volume hierarchies (BVHs) for ray tracing. The algorithm is based on modifying an existing BVH to improve its quality, and executes in ...
SGRT: A Mobile GPU Architecture for Real-Time Ray Tracing
(ACM, 2013)
Recently, with the increasing demand for photorealistic graphics and the rapid advances in desktop CPUs/GPUs, real-time ray tracing has attracted considerable attention. Unfortunately, ray tracing in the current mobile ...
PixelPie: Maximal Poisson-disk Sampling with Rasterization
(ACM, 2013)
We present PixelPie, a highly parallel geometric formulation of the Poisson-disk sampling problem on the graphics pipeline. Traditionally, generating a distribution by throwing darts and removing conflicts has been viewed ...
Theory and Analysis of Higher-Order Motion Blur Rasterization
(ACM, 2013)
A common assumption in motion blur rendering is that the triangle vertices move in straight lines. In this paper, we focus on scenarios where this assumption is no longer valid, such as motion due to fast rotation and other ...
Real-time Local Displacement using Dynamic GPU Memory Management
(ACM, 2013)
We propose a novel method for local displacement events in large scenes, such as scratches, footsteps, or sculpting operations. Deformations are stored as displacements for vertices generated by hardware tessellation. ...
Real-Time High-Resolution Sparse Voxelization with Application to Image-Based Modeling
(ACM, 2013)
We present a system for real-time, high-resolution, sparse voxelization of an image-based surface model. Our approach consists of a coarse-to-fine voxel representation and a collection of parallel processing steps. Voxels ...
