To make a flat object look 3D in Illustrator, you primarily use the 3D & Materials effects panel, particularly the Extrude and Revolve options, which add depth and dimension to your artwork.
Essential 3D Techniques in Illustrator
Adobe Illustrator offers powerful tools to transform 2D vector graphics into realistic or stylized 3D objects. The most common methods involve applying 3D effects from the Effect menu.
Using the 3D & Materials Panel
The modern way to create 3D objects in Illustrator is through the 3D & Materials panel. You can access this panel via Window > 3D and Materials. Once the panel is open and you have an object selected, you'll see options like Object, Materials, and Lighting. Under the "Object" tab, you can choose from various 3D types:
- Plane: Lays the object flat in 3D space.
- Extrude: Adds depth by extending the shape along a third axis.
- Revolve: Spins a profile shape around an axis to create a lathed object.
- Inflate: Gives the object a puffed-up or inflated appearance.
Applying the Extrude Effect
The Extrude effect is a fundamental way to give a flat object depth. As seen in demonstrations (like the referenced video segment around 1:43), applying Extrude to an object:
- "will give you that depth."
- Allows you to "rotate" the object to view it from different angles.
- Makes the object look "amazing right so this is 3D."
Here’s a basic process to apply the Extrude effect:
- Select the 2D object you want to make 3D.
- Go to Window > 3D and Materials to open the panel.
- With the object selected, click on the Extrude option under the "Object" tab.
- Use the controls in the panel to adjust:
- Depth: Controls how far the object extends back.
- Twist: Rotates the extrusion along its depth.
- Taper: Narrows or widens the extrusion.
- Rotation: Allows you to rotate the object in 3D space (X, Y, and Z axes) to find the perfect perspective.
You can also add a Bevel under the Extrude options to give the edges a rounded or angled finish, further enhancing the 3D appearance.
Utilizing the Revolve Effect
For shapes that are essentially half of a symmetrical object (like half a vase, a ring, or a sphere), the Revolve effect is used. It spins the selected path around an axis to create a 3D form. The reference also mentions "revolve" as another method for creating 3D objects.
Other 3D Effects (Inflate)
Illustrator's 3D & Materials panel also includes the Inflate option, which gives a rounded, air-filled look to flat objects.
Adding Materials and Lighting
Beyond just the object's shape, the 3D & Materials panel allows you to apply textures (Materials) and control the lighting direction, intensity, and color (Lighting). These elements are crucial for adding realism and defining the object's form and shadows, making the 3D effect more convincing.
By combining these techniques – choosing the right 3D object type (like Extrude or Revolve), adjusting its properties, and refining with materials and lighting – you can effectively transform flat vector artwork into dynamic 3D illustrations within Adobe Illustrator.
