3D models – a brief primer

User Rating: / 0

3D models, for the purpose of this brief article, are essentially three dimensional vector-based source images. They are defined internally in terms of polygons of varying sizes. These polygons are all defined in terms of size, shape, color, texture and a plethora of possible lighting effects, and are related to each other in terms of fully three-dimensional positioning.

3D rendering software allows the artist to digitally control things like scale, perspective, lighting, materials, textures, colours and backgrounds before rendering a 2D raster image. This means that :

  1. the artist can render any number of images from the same model with very little if any incremental cost
  2. the artist can render each image quite differently in terms of resolution, scale, perspective, lighting, materials, textures, colours and backgrounds
  3. the artist can develop 3D models with a startling degree of detail, and even photo-realistic definition
  4. the artist can relatively easily generate highly effective 24fps 3D animations


Finally, as is the case with 2D vector and raster stock images, a wide selection of pre-built 3D models is widely available for digital purchase - and often at little cost. These models can be used as is or can be edited and customised as required. For example, any surface in a model can be made to incorporate a company logo in a completely integrated manner. In short, the client gets tremendous choice and flexibility while the artist can focus on the job-driven aspects involved in the rendering, rather than the authoring, process.
