الرسم ثلاثى الابعاد single point perspective
single point and two point perspective. The basic example below shows how to construct a simple single point perspective drawing of a cube. Using the same skills more complex drawings/designs can be drawn, after a little practice.
point (marked with an 'X').
perspective of the cube so that the lines that make up the cube are dark and sharp. Try completing the drawings of L-shapes and T-shapes in single point perspective: single point perspective:
Single point perspective - vanishing points 1
Altering the position of the VP changes the view of the object being drawn. For example, to look down at the top of the object the vanishing point must be above. However, to look up at the object the vanishing point must be below .
The animation of the chair displayed below emphasises the importance of positioning the vanishing point carefully. This chair is drawn with two vanishing points (this is called two point perspective). When the VPs are above the chair the view is also from above, looking downwards. However, when the VPs are moved below the chair the view also changes so that we are know looking from underneath.
Round section steel tube chair
Read and practice the work on the earlier sheets covering single point perspective before attempting this sheet. Draw the chair shown below, following the basic instructions alongside each diagram. The chair below is manufactured from round section steel tube. This makes it a little easier to draw in perspective than regular square section material.
1. Draw the side view of a chair and mark the single vanishing point with an X. Note the position of the vanishing point. It has been placed on the left hand side so that the seat of the chair can be seen when the perspective drawing is complete.
You may need to experiment a little with the position of the vanishing until you find what you consider to be the right place.
2. Draw faint lines from each corner/edge of the chair projecting them back to the vanishing point.
Notice how the top and bottom of each leg has been shaped to give the impression of curved surfaces (round section steel tube)
Add the width to the chair and shade/colour.
3. Add colour and shape.
Remember, steel is often chromed (a silver, reflective surface). Choose a colour such as grey to reflect the type of material used to manufacture the chair.
Traditional chair in single
A square section wood frame chair is much more difficult to draw accurately in single point perspective.
1. Draw the side view of a chair and mark with an X the single vanishing point. The legs are thicker than the steel chair on the previous page.
Experiment a little with the position of the vanishing point until you find what you consider to be the right place.
2. Draw faint guidelines from each corner/edge of the chair projecting them back to the vanishing point.
You may need more guidelines because of the square section of each leg.
Look carefully at the way the ‘lined up’ using the guidelines.
3. Add shade and colour to the chair. Look at the colouring and shading section of this section of the website.
Drawing a table in single point perspective
A three dimensional view of a traditional wood kitchen table is seen below. Draw the table or a similar one in single point perspective.
Draw a side of the table and the position of the vanishing point. Positioning the vanishing point high on the left or right hand side means that one side of the table will be seen when the drawing of the table is completed.
2. Starting with the table top, project guidelines back to the vanishing point and complete drawing the top.
Then project more guidelines for each of the front legs, adding thickness to each one.
3. The most difficult part is ensuring that the back legs line up with the front legs. One way of ensuring that this happens is to project faint lines as shown on the drawing below.
4. Add suitable colour /shade using a coloured pencils.
Include wood grain to the top of the table.

Examples of single point perspective
The 3D representation of a simple dressing table is shown below. Draw the same or a similar dresser, in single point perspective, after following the written instructions and diagrams representing each stage.
1. Draw the cuboid shape, the basic shape of the dressing table. 2. Construct the draws remembering to project all guidelines back to the vanishing point.
3. Add simple door handles and a mirror on the top. Notice how the door handles line up vertically.
