Post-Processing Effects are image-based techniques applied after the main rendering pass to enhance the visual output. Common effects in Three.js include bloom, depth of field, motion blur, and vignette.
Use Case:
Post-processing is essential for adding cinematic flair or guiding the viewer’s focus in applications like movies, games, and interactive experiences.
Advantages:
- Improves the mood and aesthetic of scenes with effects like bloom and chromatic aberration.
- Adds a layer of realism without altering the base geometry or lighting.
- Highly customizable with the use of the
EffectComposerand shader passes.
Limitations:
- Can significantly impact performance in real-time applications, especially with multiple effects.
- Requires tuning and balancing to avoid overprocessing, which can detract from realism.
