What are 3D icons?

3D icons are digital representations of objects or symbols that exhibit depth and volume. This visual effect, characteristic to this icon style, is created through the application of various techniques, including shading, highlights, shadows, and perspective, which together generate the illusion of three-dimensionality on a standard two-dimensional screen.

While these icons appear to possess volume, it’s important to note that the majority of 3D icons found in user interfaces employ a technique often referred to as “fake 3D.” This approach simulates a three-dimensional shape within the constraints of a 2D plane, providing a visual sense of depth without true three-dimensional geometry.

How do you create 3D icons?

Creating 3D icons: understand modeling, choose software, plan, model, detail, texture, light, camera, render, export.

You create 3D icons by following the step-by-step guide below.

Understand the basics of 3D modeling: Before you start, familiarize yourself with fundamental 3D concepts like vertices, edges, faces, and depth. This will help you grasp the tools and techniques involved.
Choose a 3D modeling software: There are various software options available for creating 3D models, including Blender (free and open-source), Cinema 4D, Autodesk Maya, 3ds Max, and SketchUp. Choose one that suits your skill level and budget.
Plan your icon design: Just like with flat icons, it’s helpful to sketch out your idea or plan the shape and form of your 3D icon before diving into the software. Consider the perspective and the level of detail you want to achieve.
Start with basic shapes: Most 3D modeling starts with primitive shapes like cubes, spheres, cylinders, and cones. Begin by adding these basic forms to your scene and then manipulate them to create the overall structure of your icon.
Model the icon: Use the tools within your chosen software to sculpt, extrude, and otherwise modify the initial shapes into the desired form. This might involve adding more geometry, refining curves, and shaping the details of your icon.
Add details and refinements: Once the basic shape is in place, you can start adding smaller details and refining the overall look. This could include adding bevels to edges, creating indentations, or adding smaller elements to enhance the icon’s visual appeal.
Apply materials and textures: To make your 3D icon visually interesting, you’ll need to apply materials and textures to its surfaces. Materials define how light interacts with the object (e.g., shiny, matte, rough), while textures add surface detail like color patterns or bumps.
Set up lighting: Lighting plays a crucial role in how your 3D icon looks. Experiment with different types of lights (e.g., point lights, spotlights, area lights) and their positions to create the desired highlights and shadows that give your icon depth and dimension.
Position the camera: The camera in your 3D software determines the viewpoint from which your icon will be rendered. Position and orient the camera to get the best angle and framing for your icon.
Render the icon: Rendering is the process of generating a 2D image from your 3D scene. Your software will calculate how light interacts with your model and produce a final image. Adjust render settings like resolution and quality as needed.
Post-processing (optional): After rendering, you can further enhance your icon using image editing software like adobe photoshop or gimp. This might involve adjusting colors, adding subtle effects, or compositing the icon onto a background.
Export your icon: Finally, export your rendered 3D icon in a suitable image format. Common formats include PNG (often used for icons due to its support for transparency) and jpeg. You might also consider exporting different angles or variations of your icon.
