Part 3: Project 4: Exercise 2 – Angular perspective


Two-point or angular perspective. The limitations of parallel perspective make it impossible to depict ‘corner-on’ views of objects, i.e. when an object doesn’t have a straight edge facing the viewer. Angular perspective was developed for views of this kind so that, for example, two sides of a building which are actually at right angles to each other can be drawn receding to two separate vanishing points.

Make a line drawing of a building or several buildings seen corner-on. If this isn’t possible, arrange a group of books on a table with the books all seen corner-on. The books should be different sizes, with some placed on top of others.

Use every possible vertical or horizontal reference to ensure that receding lines are drawn at the correct angles. If you’re drawing buildings remember that the vertical corner of the building itself is an excellent reference.

When you’ve drawn the objects as accurately as possible, draw in your eye level and extend receding lines to it. If you’ve drawn buildings outdoors you’ll want to do this part of the exercise afterwards at home. All parallel lines should meet on your eye level but, in this drawing, you’ll have many vanishing points and you’ll discover that most of them will be off your paper.

This drawing relies strongly on the use of perspective to draw your eye along the street and thus creates a busy city scene rather than a straightforward architectural drawing. Check the accuracy of the drawing by copying a simplified version into your sketch book and then continuing the perspective lines to the vanishing point.

This is a sketch of our house in Balnain, Glenurquhart standing face on to the corner of the building and showing the angular, two point perspective, with two vanishing points along the horizon line/eye level – VP’s to left and right of the building.

I also made a rough sketch of Bone’s “Rome” pencil sketch and extending the perspective lines – mostly to a single vanishing point on the horizon line/eye level. There are a couple of the perspective lines that are a bit of a mis-match, but I suspect this is due more to my inaccuracies of line.
