Chapter 12.1, Problem 29PPS

(a)

To determine

To draw a perspective drawing using a vanishing point and a rectangle above the point to make the 2-D drawing appear 3-D

Explanation of Solution

Given Information: From one vanishing point objects can be drawn from different point of view as shown below

  

Step 1:

Draw a horizontal line and vanishing point on the line

  

Step 2:

Draw a rectangle above the above the vanishing point.

  

Step 3:

Using the vanishing point draw the perspective drawing of the rectangle above the line.

  

(b)

To determine

To draw a perspective drawing using a vanishing point and a rectangle below the point to make the 2-D drawing appear 3-D

Explanation of Solution

Given Information: From one vanishing point objects can be drawn from different point of view as shown below

  

Step 1:

Draw a horizontal line and vanishing point on the line

  

Step 2:

Draw a rectangle above the below the vanishing point.

  

Step 3:

Using the vanishing point draw the perspective drawing of the rectangle below the line on the same drawing window in part (a)

(c)

To determine

To describe the different views of the two drawings in part (a) and part (b)

Explanation of Solution

From the figure (a) when the rectangle is above the vanishing point we can see the bottom of figure.

From the figure (b), when the rectangle is below the vanishing point we can see the top of figure.
