Reorder Buffer: An Energy-Efficient Multithreading Architecture for Hardware MIMD Ray Traversal
(ACM Siggraph, 2015)In this paper, we present an energy- and area-efficient multithreading architecture for Multiple Instruction, Multiple Data (MIMD) ray tracing hardware targeted at low-power devices. Recent ray tracing hardware has ... -
Decoupled Coverage Anti-Aliasing
(ACM Siggraph, 2015)State-of-the-art methods for geometric anti-aliasing in real-time rendering are based on Multi-Sample Anti-Aliasing (MSAA), which samples visibility more than shading to reduce the number of expensive shading calculations. ... -
Compiling High Performance Recursive Filters
(ACM Siggraph, 2015)Infinite impulse response (IIR) or recursive filters, are essential for image processing because they turn expensive large-footprint convolutions into operations that have a constant cost per pixel regardless of kernel ... -
An Adaptive Acceleration Structure for Screen-space Ray Tracing
(ACM Siggraph, 2015)We propose an efficient acceleration structure for real-time screenspace ray tracing. The hybrid data structure represents the scene geometry by combining a bounding volume hierarchy with local planar approximations. This ... -
Grid-Free Out-Of-Core Voxelization to Sparse Voxel Octrees on GPU
(ACM Siggraph, 2015)In this paper, we present the first grid-free, out-of-core GPU voxelization method. Our method combines efficient parallel triangle voxelization on GPU with out-of-core technologies in order to allow the processing of ... -
Efficient Ray Tracing of Subdivision Surfaces using Tessellation Caching
(ACM Siggraph, 2015)A common way to ray trace subdivision surfaces is by constructing and traversing spatial hierarchies on top of tessellated input primitives. Unfortunately, tessellating surfaces requires a substantial amount of memory ... -
Bounding Volume Hierarchy Optimization through Agglomerative Treelet Restructuring
(ACM Siggraph, 2015)In this paper, we present a new method for building high-quality bounding volume hierarchies (BVHs) on manycore systems. Our method is an extension of the current state-of-the-art on GPU BVH construction, Treelet Restructuring ... -
Deferred Attribute Interpolation for Memory-Efficient Deferred Shading
(ACM Siggraph, 2015)In this work we present a novel approach to deferred shading suitable for high resolution displays and high visibility sampling rates. We reduce the memory costs of deferred shading by substituting the geometry buffer with ... -
Adaptively Layered Statistical Volumetric Obscurance
(ACM Siggraph, 2015)We accelerate volumetric obscurance, a variant of ambient occlusion, and solve undersampling artifacts, such as banding, noise or blurring, that screen-space techniques traditionally suffer from. We make use of an efficient ... -
Perception of Highlight Disparity at a Distance in Consumer Head-Mounted Displays
(ACM Siggraph, 2015)Stereo rendering for 3D displays and for virtual reality headsets provide several visual cues, including convergence angle and highlight disparity. The human visual system interprets these cues to estimate surface properties ... -
An Incremental Rendering VM
(ACM Siggraph, 2015)We introduce an incremental rendering layer on top of standard graphics APIs such as OpenGL or DirectX in the form a virtual machine (VM), which efficiently maintains an optimized, compiled representation of arbitrary ... -
Morton Integrals for High Speed Geometry Simplification
(ACM Siggraph, 2015)Real time geometry processing has progressively reached a performance level that makes a number of signal-inspired primitives practical for on-line applications scenarios. This often comes through the joint design of ...
