Trang 1

3. You can keep using the current tool, the Shape tool; click the guy with his hat in his hand Then choose Effects | Copy Effect | Perspective From Click over the guy at left who has perspective as shown here, and the second object adopts the perspective

of the first

4. Repeat step 3 for the guy holding the writing pad

5. Create a graph paper object that fills most of the page, and then give it a medium-gray fill and a white outline Put it to the back of the illustration layer by pressing

SHIFT+PAGE DOWN

6. Put the graph paper in perspective to make a ground plane Next, drag the top-left control handle to the right, and then drag the top-right control handle to the left until you see a vanishing point just above the graph paper object Now drag the top and right-top control nodes down until the perspective looks like that shown in the figure This object will not and should not be in the same perspective as the characters, but instead its perspective should be very distorted, suggesting a horizon

at about the chest level of the characters

7. Create a second graph paper object, fill it with medium gray, and give its outline a white property exactly like you did with the first object in step 5 Put it to the back

of the drawing (SHIFT+PAGE DOWN)

Trang 2

8. If you haven’t already read Chapter 22 on shadows, here are the simple steps to

“grounding” the characters on the graph paper below them: click one of the fellows,

and then choose the Drop Shadow tool from the Effects group of tools on the

toolbox

9. Choose Perspective Top Left from the Presets drop-down on the property bar With

your cursor, click-drag to adjust the black control marker for the shadow until it

looks correct

10. Repeat step 9 with the two other commuters: select a guy, and then choose Effects |

Copy Effect | Drop Shadow From, and click the first shadow (not the object casting

the shadow) you defined You can also add a shadow to the train and the cloud group

of objects Additionally, try moving the commuters up or down from their original

position to increase the sense of depth in the scene Your scene should look like

Figure 18-4 now

The preceding tutorial might have been a bit of a workout, but look at what you’ve

accomplished Often, the effect you seek is accomplished through the use of a combination

of CorelDRAW features Unfortunately, there is no “create a complete piece of artwork” tool

in CorelDRAW!

Any object that has the perspective effect can be quickly put into editing mode when

the Pick tool is the current tool, by double-clicking the object.

virtual diorama

Mirroring Perspective Control Handles

Occasionally in your design work, you might need to add perspective or adjust the existing perspective of an object so that the perspective is symmetrical This is accomplished by holdingCTRL+SHIFTwhile you click-drag a perspective control handle Here’s a creative example of the use of a symmetrical perspective: in a new document, import Bowling.png, and then follow these steps

Building a Bowling Alley

1. With the Rectangle tool, create a tall rectangle, about 1" wide and 5" high Fill it with a light brown color

2. Drag and drop three copies, each to the right of the preceding one; first, holdCTRL

to constrain your moves, then drag right, tap the right mouse button while holding the left, and then release both buttons to drop the copy

3. Group the four rectangles; after selecting them, pressCTRL+G, and then press

SHIFT+PAGE DOWNto put them behind the imported PNG picture

4. Choose Effects | Add Perspective

5. While holdingCTRL+SHIFT, click the bottom-right control node and then drag right Strike! In Figure 18-5 you can see that this technique is a convenient way to set up symmetrical perspective Optionally, you might want to useCTRL+SHIFTand then drag the top control nodes a little closer together to get the artistic effect, but you know the techniques now

Pre-Visualizing Designs in Perspective

Often you’ll design something such as a pattern and want to see what it will look like as a garment, gift wrap, or some other physical piece of art before you pay to have the design

printed; this is called pre-visualization (preVis), and you can do this in CorelDRAW with the

perspective effect In the following example, you’ll create a simple gift-wrap pattern; then, using perspective, you’ll virtually wrap a package The package is provided for you as an image on layers in a CorelDRAW document

The following set of steps begins with importing A present.cpt, a layered PHOTO-PAINT image You’ll move the image’s upper layer—the bow—to a new layer and then create an additional CorelDRAW layer to work below the bow but above the package to create a very effective illusion of gift wrap on the package

Trang 4

Let’s use CorelDRAW’s Artistic media tool to create the gift wrap for the present in the

following steps After completing the tutorial, you can use a design of your own with this

file in the future

Pre-Visualizing a Design on a Product

1. After creating a new document (choose Landscape orientation), pressCTRL+Ito

import A present.cpt Just click at the upper left of the page to place it to size

2. Open the Object Manager from the Tools menu Expand the A present.cpt entry to

reveal the two image layers To retain your sanity dealing with these “Layer” default

names, click the “Layer 1” bitmap name to select it, click it a second time to open

the name for editing, and then type Bow, because it’s the red bow on top of the

present

3. Click the New Layer button at the bottom left of the docker Doing this creates a

new default named “Layer 2.”

FIGURE 18-5 Create symmetrical perspective by holdingCTRL+SHIFTwhile you drag a

control handle

Hold CTRL+SHIFT , and then click-drag.

The opposing control handle

moves in opposite direction.

Trang 5

4. Click-drag the “Bow” entry on the Object Manager, and place it on the Layer 2 title

to move the bow image to the new layer

5. Create a new layer, by default named “Layer 3.” Click-drag it to below Layer 2 This

is where you’ll be designing the gift wrap

6. Choose the Artistic media tool from the Pen tool group on the toolbox Then choose the Sprayer button on the property bar You can use any preset you like; one of the festive Food presets is shown in the following figures

7. Create a rectangular area by scribbling up and down, like making several Ws.

8. Choose Arrange | Break Artistic Media Apart (CTRL+Kworks, too) With the Pick tool, delete the parent black path that’s now visible See Figure 18-6

Trang 6

9. Choose Effects | Add Perspective With the Shape tool, drag, one at a time, the

control handles for the effect to match the four corners of the face of the present, as

shown here

10. Duplicate the pattern (pressCTRL+D), and then use the Shape tool to edit this

duplicate (which also has the perspective effect applied) so it matches the four

corners of the top side of the present Because the bow is on the top layer, you’re

actually adding the top pattern in perspective below the bow so it looks optically

correct

11. Repeat step 10 to create the left panel of the pattern on the present

12. The pattern shouldn’t look totally opaque, but instead should take on a little of the

shading on the blank present The quickest way to apply transparency to the scores

of objects that make up your artistic media stroke is to first turn it into a bitmap

First, let’s check out the resolution of the present image so the conversion of the gift

wrap pattern isn’t unnecessarily larger than the present or bow images Click either

the Bitmap or the Bow entry on the Object Manager list, and then look at the status

bar The correct answer is 96 dpi

Trang 7

13. Select one of the patterned sides, and then choose Bitmaps | Convert To Bitmap In the Convert To Bitmap dialog Resolution box, choose 96 Check the Transparent Background check box and then click OK

14. With the new bitmap selected, choose the Transparency tool on the toolbox On the property bar, choose Uniform Transparency type, Multiply style, and then play with the amount of transparency your eye tells you looks best and that blends the pattern into the present Repeat steps 13 and 14 with the other two sides of the gift, be sure

to include a card, and then send it to someone who deserves a gift

This finished pre-visualization provides you and your client with a view of the goods you’ve designed as they will appear from the customer’s point of view, and perhaps this is the best “perspective” effect of all, as shown next

Trang 8

You’ve seen in this chapter how to take a drawing, several objects, and even a complete

design, and put a 3D spin on it Perspective effects can help a client visualize what a design

should look like when projected into real space, and at the least the perspective effect is a

fun and quick method for embellishing a drawing that needs a “certain something” to lift it

off the page Chapter 19 takes you into a more complete visualization of 3D within a 2D

drawing, as you explore the extrude effect in CorelDRAW Bring along what you now know

about vanishing points, and bring along an object or two that you want to add another

dimension to—literally!
