Struct FowRender

Source

pub struct FowRender<'a> { /* private fields */ }

Expand description

FW.2 — the render-time fog-of-war classifier: wraps a FogOfWar and answers the roxlap_core::dda::FowStyler verdict per hit. The scene renderer builds one for the twin grid each frame and hands it to the CPU DDA (DdaEnv::fow).

State → verdict:

Unseen ⇒ Hide (the marcher treats the cell as air).
Visible ⇒ Show { dynamic: true }, dimmed toward the memory look at the cone edge (intensity < max) so the FOV boundary is a smooth taper, full at the cone centre.
Memory / Heard ⇒ Show { dynamic: false } (frozen baked look), dimmed by VisionConfig::memory_dim scaled by the decaying intensity and desaturated by VisionConfig::memory_desaturate.
