MSAA (Multisample AA)

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

1. Features & Pros

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

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 Quality Check

Toggle MSAA and compare the changes in geometry edges and highlights.

Key Summary

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