3D versus 2D Modeling Methods

It can be difficult to discern the realistic 3D effects that are achieved without wireframe modeling when it is in its final form. Some programs available have incredibly complex filters that you can apply to 2D vector graphics or 2D bitmaps on transparent layers, making the final image look remarkably realistic.
However, 3D wireframe modeling has several advantages over the 2D method:

  • Flexibility: The ability to change angles or move images with a view faster, because the realistic 3D model is already there to be used.


  • Easy Rendering: Automatic calculation and rendering is easier because the 3D designer has built-in algorithms to render the rendered image realistically instead of mentally visualizing or estimating.


  • Photo-realistic resolution: You have less chance of being overly exaggerated, in error, or forgetting to include any visual effects.

So, what are the disadvantages of 3D?

  • Software learning curve: Learning 3D software can take longer because 3D modelers tend to be more complex and have more ‘under the hood’.


  • Difficult to achieve some realistic effects: You can achieve some realistic effects by using the special rendering filters included in the modeling software and intended for the 3D modeler. 3D artists sometimes use a combination of 3D model designers, followed by 2D editing of 2D computer rendered images of the 3D model.

3D modeling makes sense if you intend to fabricate or manufacture your own design. It provides a real-world model that can be viewed from any angle, 3D-printed for real-time imaging, and even submitted for non-destructive testing (a cell phone case like an iPhone, for example).
2D, on the other hand, is great for conceptual work. There is no need for a full visualization because 2D is great for approximating what a model might look like without having to create a full 3D model, thus saving time, training and costs.
