Function evaluate_deltas 

pub fn evaluate_deltas(
    original_nodes: &[[f64; 3]],
    deformed_nodes: &[[f64; 3]],
    theta: [f64; 3],
    centre: [f64; 3],
    scaling_factors: [f64; 3],
) -> Vec<[f64; 3]>

Evaluate the deltas between original and deformed design nodes.

Arguments

• original_nodes: A vector of original node coordinates. Each node is represented as [f64; 3].
• deformed_nodes: A vector of deformed node coordinates. Each node is represented as [f64; 3].
• theta: The rotation vector as [f64; 3].
• centre: The centre of rotation as [f64; 3].
• scaling_factors: The scaling factors as [f64; 3].

Returns

A vector of deltas. Each delta is represented as [f64; 3].
