Function rasterize 

Source 
pub fn rasterize<T: Trace + ?Sized>(
    scene: &T,
    camera: &Camera,
    cols: u16,
    rows: u16,
    put: impl FnMut(u16, u16, char, Color),
)
Expand description

Traces scene through camera into a cols × rows grid of braille cells with 2× supersampling.

put runs once per lit cell as (column, row, glyph, color). Cells with no dot over the coverage threshold are skipped, so whatever sits behind them shows through.
