Learning Event 1:
Two-point, or angular perspective, exists when the object is sitting at an
angle to the picture plane. In the perspective drawing of such an object,
there are two sets of horizontal lines or planes converging toward two
different vanishing points on the eye level or horizon line. The parallel
lines which slop to the right will vanish at a point in the distance called
the right vanishing point (VPR) and those that slope to the left at a point
called the left vanishing point (VPL) (fig 2-1).
2. If there are a number of objects in the drawing which are sitting at
different angles to the picture plane, each will have its own set of
vanishing points (fig 2-1).
3. To draw an object in two-point perspective in relation to a definite
viewpoint, plan and elevation views are used as shown in Figure 2-2. In the
figure, the plan view of the block was drawn first at the desired angle to
the picture plane. The position of the picture plane was then determined.
