3d Drawings
3d drawing is an excellent skill to have for work or for fun. Learning how to draw three dimensional shapes is important for artists as well as for engineers, and for people who like to sketch for fun as a hobby. 3d objects is not as difficult as you might think. These days when people talk about 3d they are usually talking about computer animation. 3D drawings are used by designers, project managers, inventors and engineers to provide an easy understanding of complex graphic designs. Stereoscopic imaging has been a major fascination for viewers and photographers since the earliest days of photography. But the word “stereoscopic” confuses some people. What does it mean? It refers to seeing with two eyes. The brain merges these two different views into a single impression that we easily take for granted, but is poorly understood by science.
This impression allows us to judge with amazing accuracy distances to and between objects. A person with single-eyed vision can also learn to estimate distances, but stereoscopic vision allows for nearly faultless determination of what is closer and what is farther. Today, we have many techniques and technologies to produce stereoscopic images. Some are more effective than others. Today's technology offers high-tech VR head-mounted displays, fast DLP projectors and glasses that contain liquid crystal shutters. Digital video and High Definition TV bring us to a new era in the evolution of this fantastic medium.
REAL 3D requires photographing two (or more) views from different angles. Any other method is synthetic and therefore not REAL 3D. The one exception is holography, which is based on principles too complex to describe here. There are certainly uses for synthetic 3D methods. But for the most part, the public can see the difference. 21st Century 3D is at the cutting edge of this rapidly advancing medium.
