Function push_xy_arc

pub fn push_xy_arc(
    radius: f32,
    nsubdiv: u32,
    dtheta: f32,
    out: &mut Vec<Point<f32>>,
)

Pushes a discretized counterclockwise arc to a buffer.

This function generates points along an arc in the XY plane (2D). The arc is contained on the plane spanned by the X and Y axes. Points are generated counter-clockwise starting from angle 0 (positive X axis).

Arguments

• radius - The radius of the arc
• nsubdiv - Number of subdivisions (points to generate)
• dtheta - Angle increment between consecutive points (in radians)
• out - Output buffer where arc points will be pushed

Example

use parry2d::transformation::utils::push_xy_arc;
use parry2d::math::Point;
use std::f32::consts::PI;

let mut points = Vec::new();
let radius = 3.0;
let nsubdiv = 4; // Quarter circle
let dtheta = PI / 2.0 / (nsubdiv - 1) as f32;

push_xy_arc(radius, nsubdiv, dtheta, &mut points);

assert_eq!(points.len(), 4);
// First point is approximately at (radius, 0)
assert!((points[0].x - radius).abs() < 1e-6);
assert!((points[0].y).abs() < 1e-6);
