- Draw a view through a doorway inside a building. Try to arrange it so that there is a rectangular rug in front to the door.
- Draw in line and check the angles of all receding lines against the horizontal and vertical lines of the door frame. Don’t use a ruler or a rubber. Re-draw the angles until you think they are correct.
- Draw in the horizon.
- Check your drawing by drawing the in-life receding parallel lines onto your image to the vanishing point.
- Use the vanishing point to draw back to correct your drawing, superimposing the new image on top of the original
Using a black drawing pen I drew the hall way of our house. I put in the horizon line with red pencil and then drew the in-life parallel lines to their vanishing point. The result was a bit of a mess. In particular the side-board was particularly wrong.
I drew back from the vanishing point with blue pencil and superimposed a second image based on these lines.
I realised that I could have put into the floor board lines, so i added them here. There is something not right with this as the side board was not at the perspective now determined by the new vanishing point lines! This means that the scale in my image must have been wrong to start with. Clearly I need to practise this!!!
I decided to do a further step using a simpler view. I chose the draw the kitchen table from 2 different heights.
I then drew on the perspective lines as in the original exercise.
My main observation with doing this simplified exercise that you don’t have to be out with your angles by very much for your perspective lines to miss the vanishing point by some way (this is proportional to distance away from the object). Accuracy is thus important.
I then went back to the original exercise and on reflection realised that I hadn’t actually followed the instructions carefully. I was supposed to frame my view with a doorway and use those horizontal and vertical lines as guides. So I repeated the exercise, this time removing all the extra details such as the hall table (that were just complicating matters). The result was better. Most of my in-life parallel lines led to the correct vanishing point. The main area of weakness was the ceiling lines to the left. I corrected them with the blue pencil lines.
