3D Anti-Aliasing Demo 4.2-31d1c0c Demos 4.2 Featured

Submitted by user Godot Engine; MIT; 2024-03-28

This project showcases the various 3D antialiasing techniques supported by Godot.

- Multisample antialiasing (MSAA): High quality, high performance cost. Does not blur the image.
- Fast approximate antialiasing (FXAA): Medium quality, low performance cost. Slightly blurs the image.
- Temporal antialiasing (TAA): High-quality, low performance cost. Slightly blurs the image (but less so than FXAA).
- Supersampling (SSAA): The highest-quality technique, but also the most expensive. Does not blur the image.
- Alpha antialiasing: Applied on certain materials in the demo, available in two modes (Alpha Edge Blend and Alpha Edge Clip). This is most effective when MSAA is enabled, as Godot enables alpha-to-coverage rendering on the material in this case. When MSAA is disabled, a fixed dithering pattern is applied on the edge of transparent areas on the material.

Godot allows using multiple antialiasing techniques at the same time. This can be useful to obtain the best possible quality, or to find a better performance tradeoff.

A resolution scale slider is also provided. When set below 100%, AMD FidelityFX Super Resolution 1.0 upscaling can be enabled to improve visuals compared to traditional bilinear filtering.
