Assignment 9: Boats and Wooden Toys
In the previous assignments we covered a lot of theory about basic shapes and construction. In this exercise we'll finally put it to some sort of use. We're going to draw wooden cars and anything made of wood that you can come up with. But first, a 'simple' exercise to warm up. This is actually an assignment where you get to design something, rather than me giving you an example to recreate :)
We'll start with some orthogonal views which we're going to translate to a perspective drawing. Orthogonal drawings are potentially a quick and easy way to design anything, as there is no perspective to take care. However, it is usefull to keep in mind that it needs to be translated into 3d once you're happy with it.
Below you see two examples of orthogonal views. Notice the difference between the two. The first one is pretty random, and while it still conveys almost the same information as the second one, it is a lot harder to put into a perspective drawing. The reason is the way its set up.
You'll notice that in the second one, the base of it is made up of squares. Squares, as you've seen in previous assignments, can easily be translated into perspective and become a cube. Cubes can be used to make sure the measurements of the ortho's stay that way into perspective so the proportions don't change. The squares are divided in sections that are more easily to find in a perspective drawing. Instead of drawing a random shape in there, the crossings of lines in there is used to built up the shape of the boat. Further down you'll see how this translates into a 3d drawing.

Now that we have a side- and front view of the object, we should be able to make a perspective drawing out of it.

Step 1: I started out by drawing the cubes first. In the sideview, the boat was two and a half square long, so I started out by setting up a sort of grid of two and a half cubes. It is easiest to divide it into halves and 1/4th pieces already, as you're going to need it later on to find certain points of the boat.
Step 2 to 4: This is basically just one step, only I thought it'd be good to show the process a bit. Use the side- and front view to find out the important points, and translate those into the 3d grid. The bow section of the boat is a good example of this. This whole exercise is a difficult version of connecting the dots.
Step 5: As you might have noticed, this drawing gets pretty complicated. All the construction lines can very easily obscure the actual boat itself, especially when you're not paying attention to line wheight :P. However, when the line drawing is finished and you didn't lose your way in the process this is the step where things become clear again. By applying shade to the boat it starts to come out of the linework of the cubes and construction again.
Step 6: To finish it off, there are several things you can do. In this case I added cast shadow on the boat itself to bring out the shape even more. Instead of adding a cast shadow on the floor though, I opted for a background. Since the lines of the cube and construction obscure the silhouette a bit and are not really needed anymore, this is a good way to get rid off them. Watch out for tangents and weird spots where the background connects with the boat. Also, if you draw the background too low it'll make you're design float :P
The assignment for now is for you to start out making the orthos as shown in the second example, then translate it to a perspective drawing like I did. The topic is to draw a boat. One warning, you might want to go all out and go wild with details and curved shapes: don't! Keep it flat surfaces, low on detail. It might not become the nicest design, but you'll find it's hard enough to translate allready.
