Struct RDPosition 

pub struct RDPosition {
    pub theta_s2: f64,
    pub theta_ba: f64,
    pub bpp: f64,
    pub ssimulacra2: f64,
    pub butteraugli: f64,
}

An encode’s position in the fixed-frame corner coordinate system.

Both angles are measured from the worst corner (max bpp, zero quality). Higher angle = better (closer to the ideal of zero-cost perfect quality).

Comparing the two angles reveals artifact character:

• theta_s2 ≈ theta_ba → uniform quality tradeoff
• theta_s2 > theta_ba → better structural fidelity than local contrast
• theta_s2 < theta_ba → better local contrast than structural fidelity

Fields

theta_s2: f64

Corner angle in SSIMULACRA2 space (degrees, 0–90).

theta_ba: f64

Corner angle in Butteraugli space (degrees, 0–90).

bpp: f64

Raw bits per pixel.

ssimulacra2: f64

Raw SSIMULACRA2 score (0–100, higher is better).

butteraugli: f64

Raw Butteraugli distance (0+, lower is better).
