3D Modeling
3D Graphics Simulate Real and Imaginary Worlds
3D modeling and animation is the art of creating computer simulations in 3 mathematical dimensions, and projecting them onto a 2D screen or paper.
Technical Aspects of Creating 3D Models
3D models are created mathematically as a series of points connected by lines. The dimensions of the finished image are determined only at the end, when the file is rendered out to a series of stills or to an animation.
As a result, 3D models are scaleable to any size without any loss of detail.
The geometry is then skinned with layers of textures that recreate further detail and the drawing style of choice. Lighting and physical effects are added and the final scene is rendered through the equivalent of a camera lens.
- Geometry can be rough or highly detailed, showing every fracture and bump. More detail requires more polygons and more rendering time, but in many cases a rough model is adequate and the detail is represented using textures.
- Textures range from flooded areas of flat colours to high-resolution photos for an effect so real you can almost feel the finish.
- Depending on the textures and a variety of options made in the final stages of modeling, the final render can be photo-realistic, hyper-realistic, or give the impression of a hand-drawn cartoon or illustration.
- In the real world, lights improve visibility and cast shadows. 3D applications are now able to emulate almost every real-world lighting fixture by company brand and model for a new level of realistic settings.
- Camera angles can capture the equivalent of a 50mm lens on a tripod, or shoot from odd angles while animated.
- The addition of film effects through video software and graphics applications such as Photoshop, allow us to enhance 3D models in new ways.
