OpenGL Programming/Anti-Aliasing

- DRAFT -

Concept keywords:

• (Spatial) Anti-aliasing
• MSAA (MultiSample Anti-Aliasing)
  • Provided by OpenGL
  • According to phoronix.com, MSAA is still in progress in Mesa.
  • Full GLUT example available at OpenGL wiki, using GL_MULTISAMPLE/GLUT_MULTISAMPLE (not producing results with Mesa 8).
• Supersampling or FSAA (Full-Scene/Full-Screen Anti-Aliasing)
  • using the accumulation buffer: cf. OpenGL Programming/Supersampling

Shader-based (with acronyms feast!):

• Fast Approximate Anti-Aliasing (FXAA): based on Intel's MLAA
• Normal Filter AA (NFAA): using edge detection
• Practical Morphological Anti-Aliasing (PMAA) and Enhanced Subpixel Morphological Antialiasing (SMAA):
