Sketch-based modeling
open-in-new
<p>Sketch-based modeling is a method of creating 3D models for use in <a href="/facts/3D_computer_graphics/zlWW6eaF">3D computer graphics</a> applications. Sketch-based modeling is differentiated from other types of 3D modeling by its <a href="/facts/User_interface/e9sPEWVD">interface</a> - instead of creating a 3D model by directly editing <a href="/facts/Polygons/yAq7RjPz">polygons</a>, the user draws a 2D shape which is converted to 3D automatically by the application. </p>
