Struct pdbtbx::TransformationMatrix

pub struct TransformationMatrix { /* fields omitted */ }

A 3D affine transformation matrix

Implementations

impl TransformationMatrix

pub fn matrix(&self) -> [[f64; 4]; 3]

Get the raw matrix (row major order)

pub fn set_matrix(&mut self, new_matrix: [[f64; 4]; 3])

Set the raw matrix (row major order), the user needs to make sure the matrix is valid

pub fn identity() -> Self

Create a matrix defining identity, so no transformation

pub fn from_matrix(matrix: [[f64; 4]; 3]) -> Self

Create a matrix with the given matrix

pub fn rotation_x(deg: f64) -> Self

Create a matrix defining a rotation around the X axis

Arguments

• deg the rotation in degrees

Panics

It panics if deg is not finite (f64.is_finite())

pub fn rotation_y(deg: f64) -> Self

Create a matrix defining a rotation around the Y axis

Arguments

• deg the rotation in degrees

Panics

It panics if deg is not finite (f64.is_finite())

pub fn rotation_z(deg: f64) -> Self

Create a matrix defining a rotation around the Z axis

Arguments

• deg the rotation in degrees

Panics

It panics if deg is not finite (f64.is_finite())

pub fn translation(x: f64, y: f64, z: f64) -> Self

Create a matrix defining a translation

Panics

It panics if any of the arguments is not finite (f64.is_finite())

pub fn magnify(f: f64) -> Self

Create a matrix defining a magnification

Arguments

• f the factor where 1.0 is the original size

Panics

It panics if f is not finite (f64.is_finite())

pub fn multiply_translation(&mut self, factors: (f64, f64, f64))

This multiplies the translation with the given factors, this can be used to convert fractional units into absolute units.

pub fn apply(&self, pos: (f64, f64, f64)) -> (f64, f64, f64)

Apply this transformation to the given position. It returns the new position.

Arguments

• pos the position (x, y, z)

pub fn combine(&self, other: &Self) -> Self

Combine this transformation with another transformation to deliver a new transformation. This transformation is applied before the other transformation.

Trait Implementations

impl Clone for TransformationMatrix

pub fn clone(&self) -> TransformationMatrix

Returns a copy of the value.
