“…Both the painterly rendering and the terrain deformations are currently being explored. Full rendering systems (Bratkova, Shirley, and Thompson 2009;Brown and Samavati 2017) mimic Berann's style regarding shading and surface texture. They also globally curve the terrain so that foreground landmarks do not mask background features.…”

I present a study of the hand-painted winter panoramas of Atelier Novat, a workshop founded by Pierre Novat (1928–2007) in the 1960s, whose style was perpetuated by his children Arthur and Frédérique. I offer a portrait of Pierre Novat and a brief historical overview of the workshop. The contribution of the paper is to describe the style of Novat through the analysis of its constituent elements: creation process, color palette, terrain deformation, light effects, and surface texture (trees, rocks, roads, and buildings). Creating an ideal yet personal representation of a mountain has a dual purpose: a practical one, to help the viewer understand the topography of the region, and an aesthetic one, to depict an imaginary mountain, now iconic of the French Alps, that encourages dreams. The paper concludes with a review of existing methods, in cartography and computer graphics, for the creation of digital panoramas.

“…Single scattering with inhomogeneous media was studied [23] by shadow map-based polygon mesh which took into account the interaction with inhomogeneous media. A later contributions to this approach were made [24] to generate volumetric fog effect. Then the Monte Carlo algorithm and neural networks were also used [25] to achieve volumetric cloud and light.…”

Adaptive volumetric light and atmospheric scattering

An adaptive sampling-based atmospheric scattering and volumetric light framework for flight simulator (FS) is proposed to enhance the immersion and realism in real-time. The framework comprises epipolar sampling (ES), visible factor culling (VFC), interactive participating media density estimating (IPMDE). The main process of proposed architecture is as follows: the scene is divided into two levels according to the distance from the camera. In the high-level pipeline, the layer close to the camera, more samples, and smaller sampling step size is used to improve image quality. Further, the IPMDE method is designed to enhance realism by achieving interactivity with the participating media and multiple light sources. Further optimization is performed by the lookup table and 3D volumetric textures, by which we can compute the density of participating media and the scattering coefficient in parallel. In the low-level pipeline, when the samples are far away from the camera, its influence on the final output is also reduced, which results in fewer samples and a bigger sampling step size. The improved ES method further reduces the number of samples involved in ray marching using the features of epipolar geometry. It then generates global light effects and shadows of distant terrain. The VFC method uses an acceleration structure to quickly find the lit segments which eliminate samples blocked by obstacles. The experimental results demonstrate our architecture achieves a better sense of reality in real-time and is very suitable for FS.

“…A similar palette is used by Google Earth for showing regions with live and dead vegetation. In a recent work, a similar palette was adopted to apply cell shading to terrain features in order to represent trees [18]. The color palette was sampled from the paintings of famous panorama maps artist Heinrich Berann in order to replicate his handdrawn style.…”

The Earth's surface is live and dynamic due to natural and manmade events. Tracking and visualizing Earth-features (e.g. water, snow, and vegetation) is an important problem. Earth observation satellite imagery like Landsat 8 makes the tracking feasible by providing detailed multispectral imagery at regular intervals. In this paper, we explore a single image summary approach to detecting changes in Earth-features by using the Landsat 8 dataset. In our system, we use appropriate thresholds for spectral indices to identify features, reference datasets, and combine multiple images using predefined color palettes to generate a single image summary of features for a region. Furthermore, we illustrate the benefit of our method over traditional visualizations with case-studies for the Lake Urmia, the Amazon Rainforest, and the Bering Glacier.
