3D modeling has capabilities to allow us to create 3D images that are as realistic as the actual objects. These images are called 3D models. These models are just like a physical model, but these can be rotated on the screen. We can display isometrics or perspectives views from a 3D model, from any angle with a few simple steps.
3D modeling is the process of developing a mathematical, wireframe representation of any three-dimensional object (either inanimate or living) via specialized software. 3D Model can be displayed as a two-dimensional (2D) image through a process called 3D rendering or used in a computer simulation. The model can also be physically created using 3D Printing devices.
3d modeling can be used for 3D Character animation, 3D graphic, 3D background, and 3D logo. Now a day 3Dimension is widely being used along with Computer Design. 3Dimension can be used in Architectural, Mechanical or Structural engineering related projects.
With the help of 3d modeling we can create 3D advertisements, which are more memorable and impressive than ordinary 2D images. Highly realistic 3D drafting images used widely in advertising and entertainment.
Designers often use 3rd Dimension to visualize designs and to make presentations. It helps them understand how an object will appear from different angles. Using additional rendering programs can further enhance the drawings.
3D modeling is usually a separate CADD module that has its own set of functions. Some manufacturers market 2D programs and 3D programs as separate packages while others combine them into a single program.
Advantages of 3D modeling
• Quickly shows whether a design idea is viable.
• Improve the design process
• Fewer (expensive) errors
• 3D modeling is a real, life sized entity built inside of the computer.
• 3D modeling is more realistic than 2D drawings.
• The importance of 3D design software is to reduce costs and thus increase competitiveness - both for companies and individuals.
With the advent of computer technology, it is now possible to create three dimensional models in virtual space, to place lights and cameras at the desired location and to assign color, form and texture to your architectural design to make it look as photorealistic as possible. Photorealistic models may be used for architectural presentations, brochure design and other design clarifications thereby helping our clients perceive ideas. 3D CAD solid models are also useful in training manuals and catalogues.
