Orthographic and isometric projections

“

- [Instructor] Technical illustrations often overcome the problems of perspective distortion by rendering images without perspective at all. This is to say that there are other forms of projecting 3D scenes into the 2D world of the screen or page. Our eyes see the world in perspective, but for clarity in visual communication, tech illustrations use orthographic and isometric projections. These are common methods for eliminating the distance-based distortion of perspective rendering. In an ortho, or isometric view, objects do not become smaller in the frame as they move away from the viewer. Measurements on the screen are proportional to measurements in the 3D scene. The simplest of these projection methods is the orthographic view. The lines of projection from the viewer into the scene are parallel to one another, instead of diverging out from the camera lens. The viewpoint is actually a view plane. This view plane is perpendicular to one of the three axes of X, Y, Z space and can be…
