Solid modeling
open-in-new
<p>Solid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes <i><a href="/facts/Solid_(mathematics)/tHH3JFoq">(solids)</a></i>. Solid modeling is distinguished within the broader related areas of <a href="/facts/Geometric_modeling/SGyQGku9">geometric modeling</a> and <a href="/facts/Computer_graphics/lapBE8wv">computer graphics</a>, such as <i><a href="/facts/3D_modeling/6V3Ry9AJ">3D modeling</a></i>, by its emphasis on physical fidelity. Together, the principles of geometric and solid modeling form the foundation of 3D-<a href="/facts/Computer-aided_design/5gSXrmmN">computer-aided design</a>, and in general, support the creation, exchange, visualization, animation, interrogation, and annotation of digital models of physical objects. </p>
