Solar System image of the main asteroid belt and the Trojan asteroids. Topics Maximum intensity projection (MIP) of a whole body PET scan. Later, visualization techniques such as hyperstreamlines were developed to visualize 2D and 3D tensor fields. Methods for visualizing vector fields include glyphs (graphical icons) such as arrows, streamlines and streaklines, particle tracing, line integral convolution (LIC) and topological methods. 2D tensor fields are often resolved to a vector field by using one of the two eigenvectors to represent the tensor each point in the field and then visualized using vector field visualization methods.įor 3D scalar fields the primary methods are volume rendering and isosurfaces. 2D vector fields are visualized using glyphs and streamlines or line integral convolution methods. The primary methods for visualizing two-dimensional (2D) scalar fields are color mapping and drawing contour lines. Primary applications were scalar fields and vector fields from computer simulations and also measured data. Scientific visualization using computer graphics gained in popularity as graphics matured. geometry-based approaches such as arrow plots, streamlines, pathlines, timelines, streaklines, particle tracing, surface particles, stream arrows, stream tubes, stream balls, flow volumes and topological analysis.Notable early two-dimensional examples include the flow map of Napoleon's March on Moscow produced by Charles Joseph Minard in 1869 the 'coxcombs' used by Florence Nightingale in 1857 as part of a campaign to improve sanitary conditions in the British army and the dot map used by John Snow in 1855 to visualise the Broad Street cholera outbreak. This prefigured modern scientific visualization techniques that use computer graphics. One of the earliest examples of three-dimensional scientific visualisation was Maxwell's thermodynamic surface, sculpted in clay in 1874 by James Clerk Maxwell. History Charles Minard's flow map of Napoleon's March. Research into how people read and misread various types of visualizations is helping to determine what types and features of visualizations are most understandable and effective in conveying information. The purpose of scientific visualization is to graphically illustrate scientific data to enable scientists to understand, illustrate, and glean insight from their data.

It is also considered a subset of computer graphics, a branch of computer science. Scientific visualization ( also spelled scientific visualisation) is an interdisciplinary branch of science concerned with the visualization of scientific phenomena.
