Flow visualization is the art of making flow patterns visible. Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to the naked eye without methods to make them this visible. Historically, such methods included experimental methods.
Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows.
Different choices of convolution kernels and random noise produce different textures; for example, pink noise produces a cloudy pattern where areas of higher flow stand out as smearing, suitable for weather visualization. Further refinements in the convolution can improve the quality of the image.
Image-based flow visualization where a grid image is advected by the flow field. In scientific visualization, image-based flow visualization (or visualisation) is a computer modelling technique developed by Jarke van Wijk [1] to visualize two dimensional flows of liquids such as water and air, like the wind movement of a tornado. Compared with ...
Architectural rendering of the Canada Permanent Trust Building, Toronto, Canada. Architectural rendering, architectural illustration, or architectural visualization (often abbreviated to archviz or ArchViz) is the art of creating three-dimensional images or animations showing the attributes of a proposed architectural design.
Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids. The development of PIV can be traced back to the early 20th ...
Product visualization software typically provides high levels of photorealism so that a product can be viewed before it is actually manufactured. This supports functions ranging from design and styling to sales and marketing. Technical visualization is an important aspect of product development.
Typically based on data and information collected from a certain domain of expertise, these visualizations are intended for a broader audience to help them visually explore and discover, quickly understand, interpret and gain important insights into otherwise difficult-to-identify structures, relationships, correlations, local and global ...
