This welcome to the 8 video and the secret to drawing video course brought to you by the virtue instructor dot com in this video we’re going to explore creating the illusion of space further with three point perspective three point perspective is a form of linear perspective that uses Lon’s to create the illusion of space on a two dimensional surface three point perspective unlike two point or one point perspective relies on three vanishing points to create this illusion. Remember there are six ways to create the illusion of space on a two dimensional surface three point perspective is one of the six ways to create this illusion. Remember unlike one and two point perspective three point perspective has one vanishing point that is placed in a location other than on the horizon line. 3. perspective is generally used to create an exaggerated point of view. So let’s take a look at it. We’ll begin with three point perspective like we have with the other two forms of perspective by defining the horizon line. Next we’ll place two of the three vanishing points on the horizon line much like we did in two point perspective in a three point perspective. We go ahead and draw lines of perspective to each of the vanishing points. Now we add a third vanishing point either at the bottom or the top of the surface. In this case I’m adding it at the bottom. Now we’ll add lines from the bottom vanishing point upward so that they intersect each of the corners of our previous four lines that we drew. Now we can draw lines to our first two vanishing points to define the top portion of our form. Here’s a look at the lines that we would keep. To define our form. All of the other lines that we used will be erased except for the ones that are bold. You may decide to add value to define your form further with three point perspective. The Vanishing Point can also be placed above. Here’s a peek at what this would look like. Now let’s do a drawing with three point perspective. Here again you need a ruler a graphite pencil and an eraser. The first thing we’re going to do is define the horizon line. Next we’ll add two vanishing points to the horizon line. Notice that in my example the second horizon line is off the picture plane. Remember this is OK then we’ll draw lines from each of the vanishing points so that they intersect. Now we’ll add our third vanishing point below. It’s off the picture plane which again is OK. Then we’ll draw lines from our third vanishing point upward so that they intersect. Each one of the corners that we drew in the previous step now will define the top portion of her form by drawing a line to one of the vanishing points. Now we’ll go to the opposite vanishing point. To help further define the top of our form we’ll add our last line to the opposite vanishing point. To finish off the top portion of the form. Now our form is there. I’ll go over the lines to make them a bit darker so that you can see them . Now we can erase any lines that we no longer need. There are a lot of extra lines to erase . Now let’s draw another form that exists behind it in space we’ll do it the same way using the same three vanishing points . We’ll begin with two lines to one of the vanishing points and then two more lines to the opposite vanishing point. This will establish the bottom portion of our form now will draw lines upward from our vanishing point at the bottom . Now we can draw lines from one of the vanishing points that rest on the horizon line then to the opposite vanishing point and then we’ll add our last line again back to the opposite vanishing point. This will define the top portion of our form. I’ll go over the lines that we need to keep this form . Now here again we have quite a number of lines to erase . To help further define our forms we may choose to add a bit of value. In this case my light sources come in from the upper left hand corner of the picture plane . Now let’s add one more form to the scene. Again two lines from one of the vanishing points on the horizon line then to the opposite vanishing point. Now lines upward from the bottom vanishing point . Next draw a line to one of the vanishing points that rest on the horizon line. Then to the opposite vanishing point. Then add the last line to define the top of your form. Here again it’s time to erase some lines will also add a bit of value to the third form . Now we can also use three point perspective to help us define where the cast shadows are. In this case our light source is coming from the left side so I’m extending our lines perspective out on the right side of the forms. This will help us define where our cast shadows may be . So what did we learn in this video. Well first we learn that three point perspective is another form of linear perspective that uses lines to create the illusion of space in a drawing. We also learn that three point perspective uses three vanishing points unlike two point perspective which uses two and one point which uses one three point perspective is generally used to create an exaggerated point of view with two vanishing points placed on the horizon line in one place to either below or above in the next video we’re going to take a look at specific drawing techniques to apply mediums.
