## Questions about this video

What are the two methods to set up vanishing points in Lazy Nezumi Pro?

You can either move the vanishing point handles directly if you know their positions, or use the VP Setup mode where you align vanishing lines to parallel lines in the scene to automatically set the vanishing point.

How does the Linear Perspective ruler differ from the Vanishing Lines ruler?

The Linear Perspective ruler does not require manual vanishing point placement; instead, it uses parameters like view center, horizon, and angles to automatically define perspective, offering more advanced control.

How can you match an existing scene's perspective using Lazy Nezumi Pro?

First, set up vanishing points using the Vanishing Lines ruler aligned to the scene, then use the 'Match current Vanishing Lines Ruler' button in the Linear Perspective ruler to transfer the setup for easier drawing.

Speaker A

So you've found a cool scene from a movie or show, and it's inspired you to draw a scene using the same perspective.

00:08

Speaker A

This video will show you how to use Lazy Nezumi to match the perspective of that scene.

00:12

Speaker A

To get the most out of this video, you first need to understand what vanishing points and vanishing lines are. If you don't know what these are, I recommend you go watch some beginner perspective drawing videos first.

00:23

Speaker A

So the first thing you'll want to do is get a screenshot of the scene you want to match, and load it up into a layer of your document. Here we'll be using a very simple artificial scene for demonstration purposes.

00:35

Speaker A

Now open up Lazy Nezumi and select a preset that uses the Vanishing Lines ruler.

00:40

Speaker A

You can have up to 6 vanishing points active with this ruler, but right now we'll only be using 3, so go ahead and uncheck VP4 through 6.

00:51

Speaker A

So there are two ways to set up a vanishing point with this ruler. The first is by simply moving its handle directly. You can bring up the handles by holding down the control key. If you know exactly where your vanishing points should be, this is fast and easy. But in this case, we're matching an existing scene, and we don't know where they are, so we'll use the second method instead.

01:05

Speaker A

Bring up the handles and click the VP1 Setup handle. We're now in VP setup mode. In this mode, you'll see two lines with two handles each.

01:11

Speaker A

These are the setup lines. Both of these are vanishing lines that connect to the same vanishing point. So in this mode, instead of moving the vanishing point, you move the vanishing lines, and the vanishing point is automatically set at their intersection point.

01:20

Speaker A

Now what you want to do is line up each of the setup lines with two lines in your scene that are parallel to each other and the ground. And when you're doing this, try to find the longest parallel lines that are as far away from each other in the image as possible.

01:34

Speaker A

This will give you a more accurate position for the vanishing point. Here we'll use the sides of the checkered quad, which we'll assume is our ground plane.

01:47

Speaker A

You'll now see that the guideline that follows your pen will line up with all the other parallel lines. This will confirm that the vanishing point has been set up correctly.

02:02

Speaker A

Now press the shift key to set up the second vanishing point. Here we'll do the same thing: we'll line up our setup lines with lines that are parallel to each other, but that are also orthogonal to the lines going to VP1. In this case, we're assuming that the checkered quad is a square, so we'll just use the opposite sides.

02:14

Speaker A

Once VP2 is looking good, press shift again to set up the 3rd vanishing point. Here we'll line up the setup lines with vertical lines in the scene that are orthogonal to the ground plane.

02:26

Speaker A

And again, for best results, try to use lines that are far away from each other in the image.

02:42

Speaker A

We'll use the sides of these cubes here. Once this is done, we can go ahead and exit out of VP setup.

02:53

Speaker A

We now have three vanishing points that match the three main axes of our scene, and the rulers can now help us draw new lines along these axes.

02:58

Speaker A

Now this is already pretty useful, but what if we wanted to draw some objects in this perspective that aren't aligned to the grid on the floor? We'd have to change the vanishing points, but without reference lines to the orientations we wanted to use, it would be very challenging with this ruler.

03:16

Speaker A

This is where Lazy Nezumi's Linear Perspective ruler comes in! As you can see from the UI, this ruler is a bit more advanced than the Vanishing Lines ruler.

03:30

Speaker A

But it's really worth diving in to, as it'll give you much greater control over the perspective of your drawing.

03:46

Speaker A

With this ruler, you don't set up the vanishing points yourself. You don't even have to think about where they should be. Instead, everything is set up for you by specifying a view center and various angles. Let's take a look at how this works.

03:57

Speaker A

The orange horizontal line is the perspective horizon, and the center point is the center of your view. You can move the center via its handle, and you can slide it horizontally or vertically by holding Ctrl+Shift while dragging it.

04:03

Speaker A

The orange circle shows the extent of your field of view. You can change its radius via the parameter slider or the handle. When starting a new scene, decide how much of your document should cover this field of view, and set the view radius accordingly.

04:16

Speaker A

Changing the field of view is like changing the focal length of a camera. Setting it to a small value is like using a telephoto lens, and using a large value is like having a wide-angle lens. Human vision is around 120 degrees.

04:32

Speaker A

Note that it's OK to just leave these parameters at their default values when you're starting out.

04:47

Speaker A

You'll eventually get a better feel for what values you want to use for different scenes.

05:02

Speaker A

You can also rotate the horizon via the Horizon Tilt parameter, or by using the handle.

05:06

Speaker A

And you can tilt the view via the View Tilt parameter, or by using the handle on the blue vanishing line. This is like tilting the camera up towards the sky, or down towards the ground.

05:10

Speaker A

So the center position and these first four parameters are used to define the general perspective of your scene.

05:20

Speaker A

You'll want to adjust them before you start adding elements to the scene, and once you're happy with the perspective and are ready to start drawing, you should leave them alone.

05:34

Speaker A

This ruler has three main vanishing lines used for drawing. If you set the Line Select Mode to Auto Start, you can just start drawing and your line will snap to the closest matching vanishing line.

05:40

Speaker A

But for more control, you can set the Line Select Mode to Manual Start. In this mode, you select the line you want to draw on by first pressing shift.

05:49

Speaker A

The blue line is used for all the vertical lines in your scene, and is set up via the View Tilt parameter, as we previously saw.

06:10

Speaker A

The green and red lines, called Line 1 and Line 2, work a little differently. These lines lie on the ground plane, and their angles are measured with respect to the center line, which is the line going from the camera to the view center.

06:30

Speaker A

You can lock these two lines together by clicking the little link icon. When they're locked, their angle difference remains constant when you rotate either one.

06:40

Speaker A

Let's lock them while they're 90 degrees apart and draw some rotated squares. While drawing, you can press Control to switch lines without lifting the pen.

06:54

Speaker A

This will give you perfectly connected corners. I also have the Box Mode option enabled right now, which prevents lines from overshooting when drawing closed shapes.

07:04

Speaker A

You can also tilt line 1 and 2 vertically. In this case, the angle is measured from the ground plane.

07:19

Speaker A

This will help you draw inclined surfaces such as roofs and ramps. Note that you can rotate in 5-degree increments if you hold Ctrl and Shift while dragging the handles.

07:39

Speaker A

And you can double-click any handle or parameter slider to reset it to its default value.

07:45

Speaker A

OK. So now that we've seen what we can do with the Linear Perspective ruler, let's go back to our demo scene.

08:05

Speaker A

Because this ruler has so many parameters that control the perspective, it used to be almost impossible to match an existing scene with it.

08:12

Speaker A

You could get pretty close by carefully adjusting each parameter one by one, but this was time-consuming and pretty frustrating honestly.

08:18

Speaker A

Thankfully there's a much easier way to do this now, which is the whole point of this video!

08:25

Speaker A

So first, let's switch to the Vanishing Lines ruler and check that everything is still lined up.

08:34

Speaker A

Everything still looks good! Ok, so now go back to the Linear Perspective ruler and click the button at the bottom that says "Match current Vanishing Lines Ruler."

08:38

Speaker A

And that's it. It's now that easy. Just keep in mind that for this to work correctly, your VP3 lines must line up with vertical lines in your scene, and your VP1 and VP2 lines must lie on the ground plane and be orthogonal to each other in the scene (in other words, be 90 degrees.

08:48

Speaker A

Everything still looks good! Ok, so now go back to the Linear Perspective ruler and click the button at the bottom that says "Match current Vanishing Lines Ruler".

09:00

Speaker A

And that's it. It's now that easy. Just keep in mind that for this to work correctly, your VP3 lines must line up with vertical lines in your scene, and your VP1 and VP2 lines must lie on the ground plane

09:14

Speaker A

and be orthogonal to each other in the scene (in other words, be 90 degrees apart).

09:19

Speaker A

You can also setup a keyboard shortcut for this function, so you don't have to use the button. Go to [Settings/Edit Shortcuts], and scroll down.

09:28

Speaker A

This one is shared with various other ruler fitting algorithms. I have it set here to F4.

09:35

Speaker A

Just for fun, let's completely mess up the perspective, and watch it perform the matching again.

09:48

Speaker A

Awesome! So now that we have the perspective matched to our scene, we can use the rulers to draw perspective-correct elements in any orientation we want!

11:20
