Chapter 7

Working with Distortions, Gradient Meshes, Envelopes, and Blends

Objectives

• Edit colors and distort objects

• Work with gradient meshes

• Work with envelopes

• Create blends

Edit Colors and Distort Objects

• Illustrator provides a number of effects that you can use to alter the shape of an object.

• The Pucker & Bloat effect adjusts the segments between an object’s anchor points.

Before Pucker effect

After Pucker effect; segments appear curvedinward

Original shape of object is evident by bounding box

Edit Colors and Distort Objects

• The Bloat effect is achieved by moving the segments outward and the anchor points inward.

Before Bloat effect

After Bloat effect—segments are moved outward

Edit Colors and Distort Objects

• The Twist effect rotates an object more sharply in the center than it does at the edges, creating a whirlpool effect.

After Twist effect; center is rotatedmore than edges

Edit Colors and Distort Objects

• The Edit Colors commands on the Edit menu are very useful for quickly applying color changes to objects.

• The changes are applied directly to the objects; they are not effects.

Edit Colors and Distort Objects

• You can saturate colors or desaturate colors in an illustration.

• You can also use the Convert to Grayscale and Blend Front to Back commands.

Saturate filter intensifies color

Convert to Grayscale filter removes all chromatic color

Work with Gradient Meshes

• The Mesh tool and the Create Gradient Mesh command can be used to transform a basic object into a mesh object.

• A mesh object is a single, multicolored object in which colors can flow in different directions, and colors transition gradually from point to point.

Work with Gradient Meshes

• When you create mesh objects, multiple mesh lines crisscross the object.

• Mesh points are diamond-shaped and work like anchor points.– Can be assigned a color– When assigned, color flows outward from

point

• Area between four mesh points is a mesh patch.

• Apply color to all four mesh points simultaneously by applying color to patch.

Work with Gradient Meshes

• You can apply opacity settings to a mesh point on a gradient mesh.

• Select one or more points on the mesh, then drag the slider in the Transparency panel.

Work with Gradient Meshes

• Mesh points can be added, deleted, and moved along mesh line without altering mesh shape.

• Manipulate anchor points’ direction lines to alter shape of mesh.

• The shape of the mesh is manipulated by direction lines.

• Mesh points can be moved, just like anchor points.

Work with Gradient Meshes

• You can create a mesh object from any path.

• You cannot create a mesh from compound paths or text objects.

• Use the Mesh tool or apply the Create Gradient Mesh command.

Work with Gradient Meshes

• The Create Gradient Mesh command creates a mesh object with regularly spaced mesh lines and mesh points.

Work with Gradient Meshes

• Once you create a mesh object it can’t be converted back.

• Complex mesh objects are a memory drain and may effect computer performance.– Better to create a few simple mesh objects

rather then a single complex one

Mesh points at the edge of the objects are filled with black

Three interior mesh points darkened

Work with Envelopes

• Envelopes are objects used to distort selected objects.

• Objects take on shape of envelope object.

© 2011 Delmar Cengage Learning

Work with Envelopes

• Make envelopes with: • Objects you create• Preset wrap shapes • Mesh objects

• Use envelopes with compound paths, text objects, meshes, and blends.

Top object to be used as an envelope

Resulting envelope effect

Work with Envelopes

• Create envelopes with top objects, meshes, and wraps.

• Create an envelope by using the Envelope Distort command on the Object menu.

© 2011 Delmar Cengage Learning

Work with Envelopes

• Make with Warp – 15 premade shapes

• Make with Mesh – same as gradient. meshes made with Mesh Tool.

• Make with Top Object – top most selected object.

Work with Envelopes

• Envelopes can distort objects with linear gradient fills or pattern fills.

• Click the Distort Linear Gradients or Distort Pattern Fills in Envelope Options dialog box to activate.

Create Blends

• A blend is a series of intermediate objects and colors between two or more selected objects.

© 2011 Delmar Cengage Learning

Create Blends

• Blends are created with:– Blending tool or– Make Blend command

© 2011 Delmar Cengage Learning

Create Blends

• Make blends between:– two open paths– two closed paths– objects filled with gradients– blends

© 2011 Delmar Cengage Learning

Create Blends

• The fewer the number of steps in a blend, the more distinct each object will be.

• A large number of steps creates the illusion of being continuous or “smooth.”

© 2011 Delmar Cengage Learning

Create Blends

• In Blend Options dialog box select– Specified Steps– Specified Distance– Smooth Color – default option

© 2011 Delmar Cengage Learning

Create Blends

• You can create a simple blend between open paths.

• You can create color effects with a blend and a mask.

You can apply blends to paths.

Create Blends

• Affect the appearance of a blend by manipulating its spine.

• When blend created, path is drawn between starting and ending objects – referred to as spine and manipulated like a path.

© 2011 Delmar Cengage Learning

Create Blends

• Examples:– Add anchor points to spine with Pen tool, then

move them with Direct Selection tool– Spine can be replaced by drawing a path with

Pen tool, then select it along with any blend and apply the Replace Spine command
