This paper proposes a new 3D tensor glyph called a hyperstreamball that extends streamball visualization used within fluid flow fields to applications within second order tensor fields. The hyperstreamball is a hybrid of ...

The User Interface plays a very important role in the geometric modelling systems. Different approaches have been developed in the last years, with and without the use of graphic images. As the sight is the most important ...

Neste artigo encontra-se a implementação e a avaliação de um novo algoritmo híbrido (CPU-GPU) para a identificação de estruturas conexas em volumes de dados tridimensionais. Este algoritmo explora o paralelismo tanto ao ...

In this work we present a framework of automatic non-photorealistic image processing techniques that create simplified stylistic illustrations from color images, videos and 3D renderings. To smooth low-contrast regions ...

Deep neural networks have been successfully applied to problems such as image segmentation, image super-resolution, coloration and image inpainting. In this work we propose the use of convolutional neural networks (CNN) ...

Weathering phenomena are ubiquitous to urban environments. In particular, fluid flow becomes a specially representative but difficult phenomenon to reproduce. In order to produce realistic flow effects, it is possible to ...

Light transport inside participating media, like fog or water, involves complex interaction phenomena, which make traditional 3D rendering approaches challenging and computationally expensive. To circumvent this, we propose ...

Both geometric and semantic information are required for a complete understanding of regions acquired as three-dimensional (3D) point clouds using the Light Detection and Ranging (LiDAR) technology. However, the global ...

Recent advances in distributed virtual reality systems and haptic technologies provide new opportunities to augment human sense of touch into highly complex and immersive visual simulations. Haptic feedback further enhances ...

The main objective of this work is to implement and evaluate a low cost virtual environment of an Intensive Care Unit (ICU) for educational purposes, targeting third year Nursery students who have never visited an ICU ...
