Struct structural_shapes::CompositeShape

pub struct CompositeShape {
    pub shapes: Vec<(i8, StructuralShape)>,
}

A composite composed of multiple individual shapes

let x = CompositeShape::new()
    .add(StructuralShape::Rod {
        radius: 2.0,
        center_of_gravity: (2.0, 0.0)
    })
    .add(StructuralShape::Rod {
        radius: 2.0,
        center_of_gravity: (-2.0, 0.0)
    });

Fields

shapes: Vec<(i8, StructuralShape)>

Constituent shapes

Implementations

impl CompositeShape

pub fn new() -> Self

This creates a new composite shape, identical to default

pub fn add(&mut self, new_shape: StructuralShape) -> Self

This function adds a new shape to the composite

pub fn sub(&mut self, new_shape: StructuralShape) -> Self

This function subtracts a new shape to the composite

pub fn calculate_cog(&self) -> (f64, f64)

Calculate center of gravity and update COG of members

pub fn update_cog(&mut self)

Shift structure to have cog at (0.0,0.0)

pub fn moi_x(&self) -> f64

This function returns the moment of inertia of the composite shape around the x-axis

pub fn moi_y(&self) -> f64

This function returns the moment of inertia of the composite shape around the y-axis

pub fn area(&self) -> f64

This function returns the area of the composite shape
