Classical viewing refers to the object portrayal method used by artists or architects which does not use computer graphics. Next, classical viewing considers an item in dimensions, also known as the three orthogonal directions. In addition to dimensions, the object has six principal faces which capture it from different orientations. Furthermore, classical viewing has a practical purpose in displaying a specific detail of the item, or a single principal face, and therefore implies a particular relationship between the viewer and the item. Many classical viewing jobs previously produced as hand drawings are now made using computer graphics; therefore, the knowledge of classical viewing is essential for producing the renders in classical view. Orthographic projection presents one of the classical views in which an object’s projectors are placed perpendicular to the projection plane (Angel & Shreiner, 2015). In other words, an orthographic view captures a three-dimensional object in a two-dimensional view.
Modern computer graphics projects, such as animation and video games generally appeal to photorealism. Thus, it may seem that the orthographic projection is lacking in practical application compared to photorealism. However, some projects can benefit from the use of parallel projection over photorealism. Thus, orthographic projections can provide a more accurate representation of a product from all angles for product manufacturers. The orthographic projection also clearly denotes the depth of an object, and its format favors further scaling of the image. Next, orthographic projection is also more suitable for representing complex objects than other classical views, such as the isometric or oblique view in axonometric projections (Costin, 2019). Thus, it is essential to learn about classical viewing to capture classic views and produce quality renders using computer graphics.
