Struct Arrow

pub struct Arrow {
    pub line: Line,
    pub mesh: Mesh,
    pub radius: f32,
    pub guid: String,
    pub name: String,
    pub xform: Xform,
}

An arrow geometry defined by a line and radius, the head is uniformly scaled.

The arrow is generated as a 10-sided cylinder body and an 8-sided cone head that is oriented along the line direction and scaled to match the line length and specified radius.

Fields

line: Line

mesh: Mesh

radius: f32

guid: String

name: String

xform: Xform

Implementations

impl Arrow

pub fn new(line: Line, radius: f32) -> Self

Creates a new Arrow from a line and radius.

Arguments

• line - The centerline of the arrow
• radius - The radius of the arrow body

Returns

A new Arrow with a cylinder body and cone head mesh
