MSAA (Multisample AA)

MSAA (Multisample Antialiasing) is the most standard antialiasing method supported at the hardware (GPU) level. It smoothes geometry edges by sampling boundary areas multiple times.

1. Features & Pros

• Standard Quality: A proven method that cleans up object outlines very well.
• Performance Balance: Lighter than Super Sampling (SSAA) but consumes more memory than Post-Processing (FXAA).
• Cons: Only smoothes geometry edges; it does not resolve aliasing within textures or shader artifacts.

2. Usage

Enabled via antialiasingManager.useMSAA. Enabling this automatically disables FXAA or TAA.

// Enable MSAA (Other AAs are disabled)
redGPUContext.antialiasingManager.useMSAA = true;

3. Live Example: MSAA Application

Toggle MSAA on and off to compare the changes in geometry outlines and highlights.

Key Summary

• Hardware Support: Utilizes built-in GPU features.
• Edge-Specialized: Excellent for smoothing object outlines.
• Default: Enabled by default in standard display environments.
