Struct Dda2LineInterpolator 

pub struct Dda2LineInterpolator { /* private fields */ }

Integer DDA line interpolator using Bresenham-style remainder tracking.

Port of C++ dda2_line_interpolator. Distributes rounding error evenly across all steps.

Implementations

impl Dda2LineInterpolator

pub fn new_forward(y1: i32, y2: i32, count: i32) -> Self

Forward-adjusted line from y1 to y2 over count steps.
