Expand description

A view in 3D space.

Fields§

§field_of_view_x: f64

The horizontal field of view in radians.

§field_of_view_y: f64

The vertical field of view in radians.

§image_height: u32

Image height.

§image_width: u32

Image width.

§view_id: u32

View ID.

§view_position: [f64; 3]

View position in world space.

§view_transform: [[f64; 4]; 4]

Affine transformation from world space to view space.

It is in column-major order, i.e., M[col][row].

§Format

[R_v   | T_v]
[...   | ...]
[0 0 0 | 1  ]

Implementations§

source §

impl View

Linear transformations.

source

pub const fn transform( rotation: &[[f64; 3]; 3], translation: &[f64; 3], ) -> [[f64; 4]; 4]

Return the affine transformation matrix.

It is in column-major order, i.e., M[col][row].

source §

impl View

Dimension operations

source

pub const fn aspect_ratio(&self) -> f32

Return the aspect ratio (width / height).

source

pub fn resize_max(&mut self, to: u32) -> &mut Self

Resize the view to the maximum side length of to.
