What is 3D illustration?
3D illustration is a visual style that allows you to create images that have three dimensions: height, width, and depth. Unlike flat or two-dimensional images that can only be viewed from one angle or perspective, 3D images can be viewed from different angles or perspectives, giving them a sense of depth and realism. 3D illustration can be used for various purposes, such as advertising, education, entertainment, gaming, and art.
Why use 3D illustration?
There are many benefits and advantages of using 3D illustration over traditional 2D illustration, such as:
It can create more realistic and immersive images. 3D illustration can mimic the real world by using realistic materials, textures, lighting, shadows, and reflections. It can also create images that are impossible or difficult to achieve in reality, such as fantasy creatures, futuristic scenes, or abstract shapes.
It can convey more information and emotion. 3D illustration can show more details and nuances of the subject matter by using different angles and perspectives. It can also express more emotion and mood by using color, contrast, and composition.
It can save time and money. 3D illustration can reduce the need for physical models, props, or actors by creating them digitally. It can also allow for more flexibility and creativity by allowing you to modify or edit the images easily without having to start from scratch.
Step 1: Create a vector art
The first step to create a 3D illustration in Illustrator is to create a vector art. A vector art is a type of graphic that is made of mathematical curves and shapes that can be scaled or resized without losing quality. You can create a vector art in two ways: by tracing a sketch or by drawing from scratch.
How to trace a sketch in Illustrator
If you have a hand-drawn sketch that you want to turn into a vector art, you can use the image trace feature in Illustrator. This feature allows you to automatically convert a raster image (such as a JPEG or PNG file) into a vector image. Here's how to do it:

Open your sketch in Illustrator. You can either drag and drop your sketch file into Illustrator or go to File > Open and select your sketch file.
Select your sketch and go to Window > Image Trace. This will open the Image Trace panel where you can adjust the settings for the tracing process.
Choose a preset from the Preset menu. You can choose from different presets depending on the style and complexity of your sketch. For example, you can choose High Fidelity Photo for realistic sketches, Sketched Art for rough sketches, or Black and White Logo for simple sketches.
Adjust the options as needed. You can fine-tune the tracing results by changing the options such as Mode, Threshold, Paths, Corners, Noise, and Method. You can also preview the results by checking the Preview box at the bottom of the panel.
Click on Expand to finalize the tracing. This will convert your sketch into a vector art that you can edit or modify using the selection tool or the direct selection tool.
How to draw a vector art from scratch
If you want to create a vector art from scratch, you can use the drawing tools in Illustrator. The most common drawing tools are the pen tool, the shape tool, and the pathfinder tool. Here's how to use them:
Use the pen tool to draw curves and lines. The pen tool allows you to draw any shape or path by clicking and dragging on the artboard. You can also adjust the direction and angle of the curves by using the anchor points and handles that appear when you draw with the pen tool.
Use the shape tool to draw basic shapes. The shape tool allows you to draw predefined shapes such as rectangles, circles, polygons, stars, etc. You can also modify the shape properties such as size, rotation, corner radius, etc. by using the options bar at the top of the screen.
Use the pathfinder tool to combine or subtract shapes. The pathfinder tool allows you to create complex shapes by combining or subtracting multiple shapes. You can access the pathfinder tool by going to Window > Pathfinder. You can choose from different modes such as Unite, Minus Front, Intersect, Exclude, etc. depending on how you want to merge or cut out your shapes.
Step 2: Apply 3D effects to the artwork
The next step is to apply 3D effects to your vector art. This will transform your flat artwork into a 3D object that has depth and dimension. To apply 3D effects in Illustrator, you need to use the 3D and Materials panel in Illustrator. This panel allows you to choose and apply different 3D types, adjust the depth and shape of the 3D object, and rotate, perspective, and position the 3D object. Here's how to use it:
Select your vector art and go to Window > 3D and Materials. This will open the 3D and Materials panel where you can access and use the 3D features.
Choose a 3D type from the Type menu. You can choose from four different 3D types: plane, extrude, revolve, or inflate. Each type has a different effect on how your vector art is transformed into a 3D object. For example, plane will create a flat 3D object, extrude will create a 3D object with depth, revolve will create a 3D object that rotates around an axis, and inflate will create a 3D object that expands or contracts.
Adjust the depth, twist, taper, cap, and bevel of the 3D object. You can modify the appearance and shape of the 3D object by using these options. For example, you can increase or decrease the depth of the extrusion, twist the 3D object along its axis, taper the 3D object from one end to another, cap the ends of the 3D object with a flat or rounded surface, and bevel the edges of the 3D object with a smooth or sharp angle.
Rotate, perspective, and position the 3D object. You can change the angle, perspective, and position of the 3D object by using the presets and sliders in the panel. For example, you can choose from different presets such as front, back, left, right, top, bottom, isometric, etc. to quickly change the view of the 3D object. You can also use the sliders to manually adjust the rotation (x-axis, y-axis, z-axis), perspective (horizontal and vertical), and position (horizontal and vertical) of the 3D object.
Step 3: Apply materials and graphics to the artwork
The third step is to apply materials and graphics to your 3D artwork. Materials are like skins that cover the surface of your 3D object. They can give your artwork different colors, textures, patterns, reflections, etc. Graphics are like stickers that you can place on top of your materials. They can add more details or effects to your artwork. To apply materials and graphics in Illustrator, you need to use the 3D and Materials panel in Illustrator. This panel allows you to choose and apply different materials and graphics to your 3D object, and adjust their properties and mapping. Here's how to use it:
Choose a base material from the Base Material menu. You can choose from different preset materials that have different colors, textures, and reflections. For example, you can choose metal, plastic, wood, glass, etc. You can also adjust the color of the base material by using the color picker or the swatches.
Choose an Adobe Substance material from the Adobe Substance Material menu. You can choose from different Adobe Substance materials that have more realistic and dynamic textures and effects. For example, you can choose brick, concrete, fabric, leather, etc. You can also adjust the properties of the Adobe Substance material by using the sliders or the presets.
Add new materials and graphics from external sources. You can add more materials and graphics to your 3D object by using the buttons at the bottom of the panel. You can choose from different sources such as Adobe Substance assets, Adobe Substance community, or your own files. You can also drag and drop any artwork from your Illustrator document to the panel to add it as a graphic.
Adjust the material properties and mapping. You can modify the appearance and behavior of the materials and graphics by using the options in the Properties panel. You can change the color, opacity, roughness, metalness, normal, height, emission, ambient occlusion, and mapping of the materials and graphics. You can also use the blue circular widget on the 3D object to move or scale the materials and graphics on the surface.
Step 4: Apply lighting and shadows to the artwork
The fourth step is to apply lighting and shadows to your 3D artwork. Lighting and shadows are essential for creating realistic and dramatic 3D images. They can enhance the depth, contrast, and mood of your artwork. To apply lighting and shadows in Illustrator, you need to use the 3D and Materials panel in Illustrator. This panel allows you to choose and apply different lighting styles, add and adjust individual lights, and adjust the global ambient light and environment map. Here's how to use it:
Choose a lighting style from the Lighting Style menu. You can choose from different preset lighting styles that have different colors, directions, and intensities of lights. For example, you can choose soft light, hard light, warm light, cool light, etc. You can also adjust the brightness of the lighting style by using the slider.
Add new lights and adjust their properties. You can add more lights to your 3D object by using the buttons at the bottom of the panel. You can choose from three types of lights: point light, directional light, or spot light. Each type has a different effect on how the light illuminates the 3D object. For example, point light emits light in all directions from a single point, directional light emits light in a single direction from an infinite distance, and spot light emits light in a cone shape from a specific point. You can also adjust the properties of each light by using the options in the Properties panel. You can change the color, intensity, position, direction, angle, softness, attenuation, cone angle, falloff distance, hotspot angle of each light.
Adjust the global ambient light and environment map. You can adjust the overall brightness and reflection of your 3D object by using the options in the Properties panel. You can change the color and intensity of the global ambient light, which affects the shadows and dark areas of your 3D object. You can also choose an environment map, which is an image that reflects on your 3D object. You can choose from different preset environment maps such as studio, outdoor, indoor, etc. or use your own image as an environment map.
Step 5: Render the artwork
The final step is to render your 3D artwork. Rendering is the process of generating a final image from your 3D object, materials, graphics, lighting, and shadows. Rendering can take some time depending on the complexity and quality of your artwork. To render your artwork in Illustrator, you need to use the 3D and Materials panel in Illustrator. This panel allows you to choose and apply different rendering modes, such as raster image or wireframe. Here's how to use it:
Choose a rendering mode from the Render Mode menu. You can choose from two rendering modes: raster image or wireframe. Raster image will render your artwork as a pixel-based image with ray tracing, which is a technique that simulates how light interacts with your 3D object. Wireframe will render your artwork as a vector-based image with hidden lines or visible lines, which shows the outline of your 3D object.
Adjust the rendering quality and resolution. You can adjust the quality and resolution of your rendered image by using the options in the Properties panel. You can change the quality from draft to high, which affects the smoothness and accuracy of your rendered image. You can also change the resolution from 72 ppi to 300 ppi, which affects the size and sharpness of your rendered image.
Click on Render to start the rendering process. This will generate a final image from your 3D object, materials, graphics, lighting, and shadows. You can see the progress and status of the rendering process in the panel. You can also cancel or pause the rendering process at any time by clicking on the buttons at the bottom of the panel.
