WebJan 30, 2024 · A true liquid is isotropic, meaning that its properties are uniform in all directions— the result of its molecules being in constant random motion. Crystalline solids, in contrast, are anisotropic; optical- and other properties such as thermal and electrical conductivity vary with direction.
WebMar 15, 2024 · Magneto-crystalline anisotropy (MAE) is the energy required per unit volume to change the orientation of the magnetic moments under the external magnetic field, which is required to achieve the high coercivity in the permanent magnets. In the field of computer graphics, an anisotropic surface changes in appearance as it rotates about its geometric normal, as is the case with velvet. Anisotropic filtering (AF) is a method of enhancing the image quality of textures on surfaces that are far away and steeply angled with respect to the point of view. Older techniques, such as bilinear and trilinear filtering, do not take into a…
