TextGeometry is a native Three.js class that lets you create 3D text using a font file and display it in a scene. The text is fully rendered as a 3D object, meaning you can apply transformations (scale, rotation, position) and materials (textures, lighting, etc.) just like any other 3D mesh.
- The font needs to be loaded as a JSON object (e.g., via
THREE.FontLoader) and then passed toTHREE.TextGeometry. You can customize parameters like font size, depth (extrusion), bevel thickness, and curvature.
- Use Case: Best used for titles, labels, logos, or decorative text elements that you want to interact with lighting, shadows, and scene effects (e.g., reflections or environment mapping). This method is also great for static 3D text that doesn’t need to change dynamically during the scene’s runtime.
- Advantages:
- Full interaction with the 3D scene, meaning it can cast shadows, reflect light, and even be affected by post-processing effects like bloom or motion blur.
- Allows you to create visually striking text objects that are fully customizable with materials and shaders.
- Suitable for both VR and non-VR environments, providing a sense of depth and solidity.
- Limitations:
- Since the text is geometry, it can be performance-heavy if used for long or complex strings.
- Not ideal for dynamic or frequently changing text due to the overhead of creating new geometry each time.
- Example Scenarios:
- In a virtual showroom, 3D titles or product names might be rendered with reflective materials, creating an immersive product display.
- In a VR experience, floating 3D text could be used for game titles or user interactions, fully lit and shaded to match the surrounding environment.
