Trang 13. 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 28. 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.
18 FIGURE 18-4 With the perspective effect and the use of a few drop shadows, you can build a
virtual diorama
Trang 3Mirroring 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 4Let’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 54. 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 69. 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
18
Trang 713. 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 8You’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!
