We propose a novel GPU-oriented approach for constructing binary bounding volume hierarchies (BVHs) based on the parallel locally-ordered clustering (PLOC/PLOC++) algorithm. Compared to competing high-performance GPU BVH build algorithms (PLOC++ or ...

A concurrent binary tree (CBT) is a GPU-friendly data-structure suitable for the generation of bisection based terrain tessellations, i.e., adaptive triangulations over square domains. In this paper, we expand the benefits of this data-structure in two ...

We revisit the idea of using hierarchies of k-sided discrete orientation polytopes (k-DOPs) for ray tracing. We propose a method for building a k-DOP-based bounding volume hierarchy while optimizing its topology using the surface area heuristic. The key ...

Radiance caching allows to amortize the cost of path tracing by sharing contributions of path suffices in a spatial data structure. This sharing generally introduces bias, but it can be traded with variance by terminating into the cache at deeper path ...

Complex lighting phenomenon such as the caustics often arises from specular chains of varying lengths. Thanks to recent advancement in specular light transport, we are able to address most effects caused by shorter specular chains using root-finding ...

Vector graphics includes both filled and stroked paths as the main primitives. While there are many techniques for rendering filled paths on GPU, stroked paths have proved more elusive. This paper presents a technique for performing stroke expansion, ...

Subsurface scattering is an important visual cue and in real-time rendering it is often approximated using screen-space algorithms. Path tracing with the diffusion approximation can easily overcome the limitations of these algorithms, but increases image ...

Denoising Monte Carlo rendered images is a critical challenge in computer graphics, traditionally addressed in post-processing phases. Recent advances have shifted focus towards integrating denoising directly into progressive rendering. This approach not ...

As technology advances from simple 2D designs to intricate 3D environments, the demand for high-quality visuals in video games and interactive media necessitates robust image quality assessment (IQA) techniques. Traditional methods like PSNR and SSIM, ...

Using voxel hierarchies as a generic 3D scene representation makes ray marching, antialiasing, and LOD easy. The drawback is the huge amount of memory required to store voxels, even with empty space compression. Still, GigaVoxels [Crassin et al. 2009] ...

We propose to use tetrahedrons as primitives for volume rendering and a pipeline to rasterize them. Our work relies on the recently introduced mesh shaders to encode each tetrahedron such that the rasterizer computes the depths of the front and back ...

Alpha masked geometry such as foliage has long been one of the trickier things to render efficiently, both for rasterization based approaches and for hardware accelerated ray-tracing. Recently, a new type of primitive was introduced to the Vulkan® and ...

The widespread availability of hardware accelerated ray tracing solutions is driving a gradual sea-change in the real-time graphics space. The major graphics APIs now offer standardized support for accelerated ray tracing. In the same time frame, ...

Large-scale capturing of real-world scenes as 3D point clouds (e.g., using LIDAR scanning) generates billions of points that are challenging to visualize. High storage requirements prevent the quick and easy inspection of captured datasets on user-grade ...

The simulation and rendering of the surface of a deep ocean are typically carried by computing a mesh displacement through an Inverse Fast Fourier Transform (IFFT) of an animated ocean spectrum. This process generates a spatially periodic ocean ...
