Voxel DAGs and Multiresolution Hierarchies: From Large-Scale Scenes to Pre-computed Shadows
(The Eurographics Association, 2018)
In this tutorial, we discuss voxel DAGs and multiresolution hierarchies, which are representations that can encode large volumes of data very efficiently. Despite a significant compression ration, an advantage of these ...
On the Pedagogy of Teaching Introductory Computer Graphics without Rendering APIs
(The Eurographics Association, 2018)
Teaching modern computer graphics programming has become increasingly challenging due to the advancement in the granularity of application programming interfaces (APIs). In this paper, we put forward a discussion on the ...
Area Lights in Signed Distance Function Scenes
(The Eurographics Association, 2019)
This paper presents two algorithms to incorporate spherical and general area lights into scenes defined by signed distance functions. The first algorithm employs an efficient approximation to the contribution of spherical ...
Ray Tracing Lossy Compressed Grid Primitives
(The Eurographics Association, 2021)
We propose a new watertight representation of geometry for ray tracing highly complex scenes in a memory efficient manner. Polygon meshes in the scene are first converted into compressed grid primitives, which are represented ...
Simple Techniques for a Novel Human Body Pose Optimisation Using Differentiable Inverse Rendering
(The Eurographics Association, 2022)
Human body 3D reconstruction has a wide range of applications including 3D-printing, art, games, and even technical sport analysis. This is a challenging problem due to 2D ambiguity, diversity of human poses, and costs in ...
Real-Time Path-Guiding Based on Parametric Mixture Models
(The Eurographics Association, 2022)
Path-Guiding algorithms for sampling scattering directions can drastically decrease the variance of Monte Carlo estimators of Light Transport Equation, but their production usage was limited to offline rendering because ...
Virtual Ray Tracer
(The Eurographics Association, 2022)
Ray tracing is one of the more complicated techniques commonly taught in (introductory) Computer Graphics courses. Visualizations can help with understanding complex ray paths and interactions, but currently there are no ...
Quick Cone Map Generation on the GPU
(The Eurographics Association, 2022)
We propose an efficient conservative cone map generation algorithm that has T(N^2 logN) complexity for textures of dimension N ×N in contrast to the T(N^4) complexity of brute-force approaches. This is achieved by using a ...
Neural Denoising for Spectral Monte Carlo Rendering
(The Eurographics Association, 2022)
Spectral Monte Carlo (MC) rendering is still to be largely adopted partially due to the specific noise, called color noise, induced by wavelength-dependent phenomenons. Motivated by the recent advances in Monte Carlo noise ...
Transfer Textures for Fast Precomputed Radiance Transfer
(The Eurographics Association, 2022)
Precomputed Radiance Transfer (PRT) can achieve high-quality renders of glossy materials at real-time framerates. PRT involves precomputing a k-dimensional transfer vector or a k×k- matrix of Spherical Harmonic (SH) ...
