1. The drawing opposite shows two tone rendering.
A suitable colour is chosen and two sides of the
cube are shaded - one slightly darker than the other.
2. This drawing shows three tone rendering.
this is very similar to the previous example
except three shades of the same colour are used
3. Three tone rendering has been used again but in
this case a lighting effect has been added to the top.
Light is shown reflected on the top part of the cube.
This is achieved by shading in a radial pattern.
The coloured pencil follows the ‘invisible’ red guidelines.
As the rendering progresses from right to left more weight is
applied to the pencil giving a darker shade

2. 4. The example opposite shows the lighting effect
applied to all three visible sides of the cube. However,
to speed up the technique the rendering is not radial
but linear (shading is in straight lines). When shading
a side of a cube using this technique, a coloured pencil
is used in a linear fashion parallel to an edge of the cube
5. Shading: The techniques used above can be adapted.
Instead of rendering the sides of the cube - the
same colours are used but the colour process
is speeded up by drawing lines parallel to the sides.
You may notice that the darker lines are close
together whilst the lighter lines have a gap between
them. This is a quick way of adding limited colour
to a drawing.

This question is about: Rendering materials and shading
Render the drawing of the phone underneath, taking into account the light source and the materials. Add shadow where appropriate. Do not add extra text or other unwanted detail. This question is worth 15 marks.
