Overview:
Tone mapping is a technique used to convert high dynamic range (HDR) images to a lower dynamic range suitable for display. In Three.js, tone mapping enhances the realism of scenes by accurately representing light and shadow.
Use Case:
Tone mapping is essential for applications requiring realistic lighting, such as architectural visualizations or photorealistic renderings.
Advantages:
- Provides more realistic lighting effects, helping to simulate how human eyes perceive brightness and color.
- Supports various tone mapping algorithms, allowing developers to choose the best fit for their scene.
- Can significantly enhance the visual quality of 3D scenes by preserving details in both highlights and shadows.
Limitations:
- Tone mapping can add computational overhead, potentially impacting performance, especially in real-time applications.
- Requires HDR content to be effective, which may not always be available or easy to create.
Example Scenarios:
In an architectural visualization, tone mapping can be used to create lifelike lighting conditions, making the space appear more inviting and realistic by accurately portraying how light interacts with surfaces.
