Function push_circle

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

Pushes a discretized counterclockwise circle to a buffer.

This function generates points along a circle in the XZ plane at a given Y coordinate. Points are generated counter-clockwise when viewed from above (positive Y direction).

Arguments

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

Example

use parry3d::transformation::utils::push_circle;
use parry3d::math::Point;
use std::f32::consts::PI;

let mut points = Vec::new();
let radius = 5.0;
let nsubdiv = 8; // Octagon
let dtheta = 2.0 * PI / nsubdiv as f32;
let y_level = 10.0;

push_circle(radius, nsubdiv, dtheta, y_level, &mut points);

assert_eq!(points.len(), 8);
// All points are at Y = 10.0
assert!(points.iter().all(|p| (p.y - 10.0).abs() < 1e-6));
// First point is at (radius, y, 0)
assert!((points[0].x - radius).abs() < 1e-6);
assert!((points[0].z).abs() < 1e-6);
