From Spectra to Perceptual Color: Visualization Tools for the Dimensional Reduction Achieved by the Human Color Sense
(The Eurographics Association, 2018)
Physical colors, defined as unique combinations of photon populations whose wavelengths lie in the visible range, occupy an infinite-dimensional real Hilbert space. Any number of photon populations from the continuous ...
A Multifragment Renderer for Material Aging Visualization
(The Eurographics Association, 2018)
People involved in curatorial work and in preservation/conservation tasks need to understand exactly the nature of aging and to prevent it with minimal preservation work. In this scenario, it is of extreme importance to ...
EUROGRAPHICS 2018: CGF 37-2 STARs Frontmatter

Monte Carlo Methods for Volumetric Light Transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
The wide adoption of path-tracing algorithms in high-end realistic rendering has stimulated many diverse research initiatives. In this paper we present a coherent survey of methods that utilize Monte Carlo integration for ...
Teaching Spatial Augmented Reality: a Practical Assignment for Large Audiences
(The Eurographics Association, 2018)
We present a new methodology to teach spatial augmented reality in a practical assignment to large audiences. Our approach does not require specific equipment such as video projectors while teaching the principal topics ...
Rigid Body Joints in Real-Time Unified Particle Physics
(The Eurographics Association, 2018)
In this paper, we propose a physically-based method for a rigid body joint simulation. The proposed solution is based on the unified particle physics engine, a simulator that uses only particles for all the dynamic bodies. ...
Growing Circles: A Region Growing Algorithm for Unstructured Grids and Non-aligned Boundaries
(The Eurographics Association, 2018)
Detecting the boundaries of an enclosed region is a problem which arises in some applications such as the human upper airway modeling. Using of standard algorithms fails because of the inevitable errors, i.e. gaps and ...
Human Sensitivity to Light Zones in Virtual Scenes
(The Eurographics Association, 2018)
We investigated perception of light properties in scenes containing volumes with dramatically different light properties (direction, intensity, diffuseness). Each scene had two light zones, defined as distinct spatial ...
A Survey on Data-driven Dictionary-based Methods for 3D Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Dictionaries are very useful objects for data analysis, as they enable a compact representation of large sets of objects through the combination of atoms. Dictionary-based techniques have also particularly benefited from ...
I3T: Using Interactive Computer Graphics to Teach Geometric Transformations
(The Eurographics Association, 2018)
Geometric transformations play an important role in a vast variety of disciplines. Although they belong to the fundamental concepts, they are also difficult to comprehend. Thousands of students take courses of algebra every ...
