This combination of 2D and 3D tools can be very powerlu o create awesome deawings.
For purely hand-drawn grids, the POV often doesn't come out exactly as desired, or the amount of Convergence is off ond emulates the wrong comera lens. In that cose you either carry on with the wrong POV, oF start over. The totel time to model and render this image was 30 minutes, so the production advantages of working this way to get started are immediately evident.

Having strong perspectivedrawing sil opens up the mory ways these types of renderings can be used. The second image in each pair wos rendered with 0. What the computer programs do is look at how much of ihe scene is cbove or below the Horizon Line, and then all vertical ines converge to Vanishing Point located on the side that is being shown the most.
This is a weird distortion, and the only place you'll oversee this effect i inside digital environments In life, when looking a! This is clearly not the case inthe videogame examples.

I's offen a great ideo to draw draft views of an object before cottempting to sketch it in perspective. Here Roy hos focused on sketching cerain areas ofthe ship from a variety of different perspecives. All of the stops to do these drowings ore the same. Drew an ellipse around the minor axis and estimte the degree of elipse.
Then, drow a bounding box around the loose elipse. The bounding box ess if he coreet degree ofthe elipse wos dawn, 3. The side view ofthe circle on the surface shows the conditions that need to be matte find the correct dagree of ellipse. There is only one circle that will fr between oll thes lines Here are the conditions tho he ciel ond the clipse need to ful: The circle touches the lef verical line halfway, eyan point.

However, fhe wheels are turned, the correct minor axis relative to the car body must be found before drawing the ellipses Always remember that drawing elleee properly requires only two things, in this order: 1 correct minor exis, fllowed by 2 the correct degree.
If the minor exis ig not correct no amount of adjustment to the degree will ever make the ellipse look righ. Keep your pencil and precision sharp to get the best results 1. Set up the ellipse in perspective, which is to be subdivided. Take the vertical height ofthe elipse ond extend it tothe side. Here, only quortercicle is subdivided, but feel fee 10 edd mote increments os needed, 3.
Drow horizontal, parallel lines trough the intersection points ofthe circle over tothe vertical line ofthe elipse.

Sure it requires more tine ond energy than using 3D modeling program, and eventually a 3D generated underlay con be used for the basie perspective grid, bu!
So here's o quick way to colelate the placement of tho spokes on a S-spoke wheel for example, by finding « repeating proportion. First, divide the upper half of e vertical centerline into ti cond the lower half of this line into quarters.
Next, draw o Tread subdivision cheat Anlipze was precicelydividedin the earlerconstuetion, butsomelimes all tho is required is to get the general look ofthe oreshortening ofthe spaces of they wrap around the ellipse. The perspective need not be technically correct, but it gives the basic visual result desire. This provides the endpoints for each ofthe spokes, Then, to locate the position of each spoke atthe hub, in ordar to create the offset wheel center, repeat the some steps on the smaller ellipse located there To do this, extond the minor axis with a parallel constuction ond subsivide from there instead of using the vertical lin.
This saves work, since he lines don't hove fo be turned bock into perspective. To place an ellipse on o sloped surface in perspective, the minor axis relative to the sloped surface needs to be determined To do this, fist draw an ellipse around the [oreen edge of the box. Theminoroxisline green is perpendicular to the surface.
Draw light ellipse around the minor axis taking your bes! To check the degree ofthe ellipse, draw three sides of bounding box, matching the perspective grid of the sloped surface.
IF the clliose's tangency points intersect properly, then the degree of the sketched ellipse is coreect. The some technique works forthe wheal of this iterah. The constuction ofthe axles ore the minor axes ofthe ellipses. This chapier will breok down and explain all ofthe most used cand helpful constuction techniques we know of to increase knowledge page-by-page until ct the end ofthis chapter almost any form can be caccurately drawn in perspective.
We have observed with our students ver the years that by tackling one face! All of the knowledge gained so far inthis book will be used so, if eorler steps were skipped, this chapter may quickly become frustrating. Don't despaic ond throw this book across the room! Taken sepbystep tis method con become second nature in your drawing.
Alter the ability to think up forms in o dra view is mastered, we wil work in perspective and stot to build out he form using sections, drawing on the X, Y and Z planes a defined by he perspecive gids and guidelines.
The occuracy of your curved surface volumes will be ively influenced by your ability "0 draw sreight nes ond to pot points using those sight lines XYZ section drawing is the core skill necessary to master drawing complex volumes, such as the vehicles in later chapters. Drawing diferent forms requtes 0 litle deductive reasoning aso the best place to put the sections, bute lot ofthis knowledge will come from practice.
When defining the surfaces of 0 volume in porspecive, they con all be drawn more eosily by using section lines. For this reason itis a good idea to develop plan by sketching several simpler views before jumping into elaborate perspective constuction drawings. Whatever you imagine the mos clearly, draw itn.
Doing this first will hop establish the overall proportions without having to worry about things like foreshortening. Here are few loose sketches illustrating this opproach. Create bounding rectangle that can be divided evenly into squores. The example on the left side of the page is defined by 0 rectangle measuring x 4.
The one on the right uses a rectongle that is 2 x 3. Within the reciongle, draw a simple shope in side view. Conversely, you con draw the shape and then the rectangle, bu! Add mote lines to create more intersection points.
Try extending the shore sections ofthe shape to soe where they would inersec the bounding rectangle. These con be a huge help when lightly added to the perspective plones ond hen used to sketch in the finshed sections Extrome freshortoning can be very dificult to predict, 20 creating more reference points makes i easier.
OK, it's time to transfer this simple side view into perspective. Create bounding rectangle in perspective with the some proportions as the side view. Use any of the techniques already presented to do this. Aer morking these simple clignments, add even more reference lines to both views. This makes it easier to locate even more points which facilitates drawing the draf view properly foreshortened in perspecive. Stort with Y plone to define the centerline ofthe form.
Draw the detired centerline on this constuction plane, Remember, only focus on the shouete of he side view of the form on this fis plan. This could have bbaen drawn first and then mirrored to the neorside; it makes no difference.
Usually i's drawn on whatever side of the form con be visvolized more easly. The diagonal mirroring method was used of the front ofthe form ond the rectangle method at the back. The volume is bosically being buil from the inside out 2. Define a flat plane thatthe volume will be sting on by adding some perspective guidelines going to the Loh Vanishing Point IVF.
Locote these guidelines of the intersection ofthe vertical guidelines end the bottom ofthe centerline. The lines on the Z plane going tothe LVP will be the location of he X sections 4, Sketch o line of the mirrored top view as accurately as posible through the reference points hot have been mirrored hve ine. Don't trust the accuracy of the mirored points to Faull, meaning tha if the frst half of he top view is smooth line without ony kinks in it, then the mirored line should also be nice smooth curve.
Since this is handdrawn sketch, the mirrored reference points might be slghily of, se keep that in mind when drawing he mirored line. When the top view was drawn in Step 2, the only constraint was that it had to line up and intersect the centerline atthe front ond back where the centerline sot on the Z plane.
Aside from intersecting the centerline a! Now i is ime for the lost step in the section drawing before outlining the silhouette ofthe volume. Add X sections at any of he section locations defined by the perspective guidelines crossing the Y ond Z plones blue lines. They con be sketched on either side ofthe centerline; jut sketch one half for now. Add ond mirror the remaining X sections.
The light green lines going to the LVP were used to transfer reference points from where the diagonals intersected the X section lines. This keeps the number of lines to minimum, resting ina cleaner construction drowing 6.
Just os the Z plone hod to intersect the Y plane centerline ot the front and back where ittouched the Z plane, the X sections alse have nt z : 1 cain «come ign evry htc nar, 2. The real world has no lines around objects, but lighly sketch architec forms over it To make the drawing look the human eye understand this shorhand. There are three options io oddress this: use a pen ora pencil hot cllows varying the weight of each line, go back and heavily ovine the object shovels in he foreground, or tke this drawing into Photoshop cd add cimosphere to reduce the conkas' ofthe lines forhest way.
This step can be done in Photoshop. Notice tht the line work out atthe horizon wos made much lighter to help this almospheric effect, whereas the lines inthe foreground ore much higher conta. In this program, once th lighting is set up property the value work is done avtomatically.
Th traditional media version completing the drawing and then rendering in Photoshop took about two hours; the MODO version took only sigh longer. As 3D medeling becomes easier, it wil became something 12 consider weaving into your workflow.

Either way is fine. On the nex! None ofthe box forms were defined by the values, only the slhovetas ofthe structures were, Some of the undersides were darkened « bit, but otherwise the value application was done to add a touch of atmospheric perspective to make the line drawing easier to read.

Ths is oneto-one reproduction of the sketch.
The finishing touch was toadd some heavier line weight with 0 0. The thin clouds, or jet tails, were added last to provide sofer, more organic shapes to contrast with the more geometric forms of the buildings. They were intentionally placed behind the larger building to add another overlapping clement, which increases the sense of depth —— sri Thm ag mre 2. The small ick marks on the left and bottom edges were placed to divide the frame into thirds, vetically and hoszantoly.
A larger building wos edded to the mid ground. When blocking out these rough building forms the composition should be the Focus, not getting the perspective exccly corect.
That comes next. Newt, figures were added to the scene. Since the ground is relatively flot, the simple perspective transfering of scale constuction was used to make sure the figures inthe distance were the some height as the one in the foreground. The reference VPs make this 0 simple thing to do which can realy help the relative scole of the structures be more easily understood in the scene. Lc three very different environments i Je.

Take time drawing the design elements that make a real object look real. This wll quickly inereate your visual library. This isa step-by-step demo of how to draw a paper airplane from a sidewview drawing in 2-point perspective. When drawing this line, think about he type of comera lens o use. For a wideangle lens, faster convergence is needed; for a long lens, slower convergence is needed. Making sure the next line drown correciy converges to the [VP presents challange because the IVP is off the poper.
Employ the Brewer Method to define the 6. To create a constuction plane thot is perpendicular to proper convergence. Start the line athe loweright corner of the last foreshoriened square. Evend this new horizontal line to the left ntl it intersects the minor exis of the ellipse.
Then add a new vertical line where the minor axis intersects with the baseline of the second square from the lef.
Double the height of he second and the last foreshortened squares using the ovlo- foreshortening consirction method. This increases he height of the RVP arid, which will make the next slep of the construction—finding oddional properly converging guidelines going to the WP— much more accurate 8.

I you hove practiced drawing smooth lines through fixed points, it will really pay off here with goodlacking drawing in perspective. These are the reference points in 3D space to star defining the wing tips.
