Struct amethyst_rendy::Camera

pub struct Camera { /* fields omitted */ }

Camera struct.

Contains a projection matrix to convert from world/eye-space into normalized device coordinates. For rendy/gfx-hal these are y-down, x-right and y-away in range [0; 1]

World Coordinate system +y | +z | / |/___+x

NDC system +z / |¯¯¯+x | +y

Methods

impl Camera

pub fn standard_2d(width: f32, height: f32) -> Self

Create a normalized camera for 2D.

Will use an orthographic projection centered around (0, 0) of size (width, height) Bottom left corner is (-width/2.0, -height/2.0) View transformation will be multiplicative identity.

pub fn standard_3d(width: f32, height: f32) -> Self

Create a standard camera for 3D.

Will use a perspective projection with aspect from the given screen dimensions and a field of view of π/3 radians (60 degrees). View transformation will be multiplicative identity.

pub fn as_matrix(&self) -> &Matrix4<f32>

Returns a reference to the inner Projection matrix of this camera.

pub fn as_matrix_mut(&mut self) -> &mut Matrix4<f32>

Returns a mutable reference to the inner Projection matrix of this camera.

pub fn projection(&self) -> &Projection

Returns a reference to the inner [Projection] of this camera.

pub fn projection_mut(&mut self) -> &mut Projection

Returns a mutable reference to the inner [Projection] of this camera.

pub fn set_projection(&mut self, new: Projection)

Sets the inner [Projection] of this camera.
