Lesson details

Key learning points

  1. Rendering helps to enhance communication of design ideas.
  2. Rendering can be used to show colour, materials and textures.

Keywords

  • Render - to add details like shading, texture, and depth to a sketch to make it appear more realistic

  • Tone - the lightness or darkness of an area, which helps create a sense of dimension in the image

  • Depth - the illusion of distance or three-dimensional space on a flat surface

  • Texture - how something feels or looks like it would feel, if touched

Common misconception

Rendering is just adding tone.

Rendering should consider tone and depth but also the texture of the material the product is made out of.

It would be useful to have different material examples as well as a collection of objects to help when practising the rendering.
