Two-Point Perspective Introduction Two-point perspective is when objects are located at an angle to the picture plane but with vertical edges parallel to the picture plane Two vanishing points are required to project the remaining dimensions. Two-point perspective is also called angular perspective because of the angular position of the object in relation to the picture plane. Two-point perspective is the most commonly used type of perspective in drawing and illustration. Two-point or angular perspective In two-point or angular perspective, an object is placed at an angle to the picture plane but with one set of vertical edges parallel to the picture plane. Place the object so that the angles created by the surface of the object to the picture plane are unequal. For convenience in drawing, the angles you select should equate to angles that a common 45° or 30/60/90° triangle or combination of the two triangles can easily replicate. The vertical parallel edge (height) appears in true length and does not require vanishing points. You may make direct measurements from this parallel vertical edge. You must use perspective to draw the remaining profile of the object. This will require two vanishing points (width and depth). The station point is located in front of and parallel to the picture plane. The object is at an angle to the picture plane and vanishing points are usually located to the left and right of the object. Visual rays projected from the station point to the vanishing point intersect the object at piercing points to form perspective. If available, you may use the plan and elevation of multiview drawings in the construction of the perspective drawings. Continued on next page
