Where we tell stories with data and design Waves of Interest By Moritz Stefaner Welcome to our data visualization project Where we tell stories with data and design Google Trends Dataviz from around the world Welcome to our data visualization project Where we tell stories with data and design What is Trending right now around the world? The interest in real-time volume graphics has grown rapidly in the last few years, driven by the increasing demands from both academia and industry. GPU-based volume rendering has been used in a wide variety of fields, including scientific visualization, visual effects, and video games. Similarly, real-time volume editing has been used to build terrain and create Visualizing volume data using physical models Abstract: Visualization techniques enable scientists to interactively explore 3D data sets, segmenting and cutting them to reveal inner structure. While powerful, these techniques suffer from one serious flaw-the images they create are displayed on a flat piece of glass or paper.

What is data visualization? Data visualization is the process of using visual elements like charts, graphs, or maps to represent data. It translates complex, high-volume, or numerical data into a visual representation that is easier to process. Data visualization tools improve and automate the visual communication process for accuracy and detail. Volume rendering is a useful technique for visualizing three dimensional arrays of sampled data. Examples of sampled 3D data can range from computational fluid dynamics, medical data from CAT or MRI scanners, seismic data, or any volumetric information where geometric surfaces are difficult to generate or unavailable. Volume visualization provides a way to see through the Different ways of visualizing a volume data set (here: abdominal CT scan) and an oblique slice. a 3D view without clipping. b 3D view with clip plane. c 2D view of the slice. d Ultrasound-like

What is Volume Visualization? Volume visualization is a technique used in data analysis and scientific computing to represent three-dimensional data in a two-dimensional format. This method allows for the exploration of complex datasets, enabling users to understand and interpret volumetric data effectively. By employing various rendering techniques, volume visualization

Visualizing Vector Volume Data Lines, Particles, Ribbons, Streams, Tubes, and Cones Vector volume data contains more information than scalar data because each coordinate point in the data set has three values associated with it. These values define a vector that represents both a magnitude and a direction. The velocity of fluid flow is an example of vector data. A number of Volumetric ray-casting is a widely used algorithm in volume visualization, but implementing this algorithm to render atmospheric volume data that cove

Techniques for Visualizing Scalar Volume Data What Is Scalar Volume Data? Typical scalar volume data is composed of a 3-D array of data and three coordinate arrays of the same dimensions. The coordinate arrays specify the x-, y-, and z -coordinates for each data point. The units of the coordinates depend on the type of data. For example, flow data might have

Pre-integrated volume rendering [13] is a method that works especially well for visualizing thin structures in volumetric data. As such it is well suited for, and has been applied to, volume rendering of seismic data [14, 15]. 7. Visualizing Volumetric Data from Cube-Files Apart from calculating trajectories various volumetric properties can be calculated with the CPMD program: e.g. electron densities, spin densities, electrostatic potentials, electron localization functions (ELF), localized and canonical (occupied) orbitals. Visualizing MRI Data An example of scalar data includes Magnetic Resonance Imaging (MRI) data. This data typically contains a number of slice planes taken through a volume, such as the human body. MATLAB includes an MRI data set that contains 27 image slices of a human head. This section describes some useful techniques for visualizing MRI data. Example — Ways to

However, one remaining challenge in the existing visualization methods is efficiently rendering marine data with large volumes and illustrating the internal structure of marine phenomena. To solve this problem, we propose a new visual analytics framework involving 4 parts for visualizing extensive marine scalar volume data.

Direct volume rendering has been an important technique for visualizing volume data. An unobstructed view on the inspected features of interest can help the user to get the insight of the volume data being explored. In this paper an exploratory volume visualization framework named Probe-Volume is presented. Probe-Volume provides a moveable and sizeable probing box for Techniques for Visualizing Scalar Volume Data What Is Scalar Volume Data? Typical scalar volume data is composed of a 3-D array of data and three coordinate arrays of the same dimensions. The coordinate arrays specify the x-, y-, and z -coordinates for each data point. The units of the coordinates depend on the type of data. For example, flow data might have Volume Viewer Volume Viewer is a tool for visualizing volume data, 3D numerical data sets such as electron density maps. The data can be shown as solid or mesh isosurfaces (contour surfaces) or as partially transparent solids:

Volume rendering refers to a set of techniques that display a three-dimensional dataset as a two-dimensional image and has been widely used in scientific visualization and engineering domains. By classifying the spatial information of volume data and projecting it onto the screen, it provides researchers a better understanding of different features within volume Visualizing Vector Volume Data Lines, Particles, Ribbons, Streams, Tubes, and Cones Vector volume data contains more information than scalar data because each coordinate point in the data set has three values associated with it. These values define a vector that represents both a magnitude and a direction. The velocity of fluid flow is an example of vector data. A number of

Volume data these days is usually massive in terms of its topology, multiple fields, or temporal component. With the gap between compute and memory performance widening, the memory subsystem becomes the primary bottleneck for scientific volume visualization. Simple, structured, regular representations are often infeasible because the buses and interconnects involved I am trying to use „slice“ function to plot volume data. And the x- and y-axis need to be scaled equally, but the z-axis need not. However, the „axis equal“ command will influence every axis.

Volume Rendering in ParaView

Visualizing volume data on an irregular grid (non-uniform rectilinear, curvilinear, unstructured, or AMR) requires additional processing and storage space. We have developed data organization, feature enhancement, and rendering techniques for more efficient visualization. Visualize Data in a Volume Your data may contain a measured value for a physical object such as temperature in a pipe. In this cases, the physical dimensions can be represented as a volume with color used to represent the magnitude of the measurement.

This lets us explore 3D data within Python, minimizing the need to switch contexts between data exploration and data analysis. The key is to use the matplotlib event handler API, which lets us define actions to perform on the plot — including changing the plot’s data! — in response to particular key presses or mouse button clicks. This example shows several methods for visualizing volume data in MATLAB®.
