Approximate EWA Filtering • Reconstruction filter radius r 3D := √ u 2 + v 2 r 3D ≤ 1 • Screen-space filter radius r 2D := d (x, y) /σ r 2D ≤ 1 • Combined filter r := min {r 3D , r 2D } w := Gauss (r) r ≤ 1 Computer Graphics Group Mario Botsch
Approximate EWA Filtering • Restrict minimum projected splat size to 2σ × 2σ pixels • Ensure enough fragments for AA • Done in vertex shader • Combine minimum of radii • Done in fragment shader • 3 additional instructions only Computer Graphics Group Mario Botsch
