Enum amethyst_rendy::camera::Projection

pub enum Projection {
    Orthographic(Orthographic),
    Perspective(Perspective),
}

The projection mode of a Camera.

TODO: Remove and integrate with Camera.

Variants

Orthographic(Orthographic)

Perspective(Perspective)

A realistic perspective projection.

Methods

impl Projection

pub fn orthographic(
    left: f32,
    right: f32,
    bottom: f32,
    top: f32,
    z_near: f32,
    z_far: f32
) -> Projection

Creates an orthographic projection with the given left, right, bottom, and top plane distances. The projection matrix is right-handed and has a depth range of 0 to 1

pub fn perspective(aspect: f32, fov: f32, z_near: f32, z_far: f32) -> Projection

Creates a perspective projection with the given aspect ratio and field-of-view. fov is specified in radians. The projection matrix is right-handed and has a depth range of 0 to 1

pub fn as_orthographic(&self) -> Option<&Orthographic>

Returns a reference to this Projection as [Orthographic] if it is in fact an Orthographic projection. Otherwise, None is returned.

pub fn as_orthographic_mut(&mut self) -> Option<&mut Orthographic>

Returns a mutable reference to this Projection as [Orthographic] if it is in fact an Orthographic projection. Otherwise, None is returned.

pub fn as_perspective(&self) -> Option<&Perspective>

Returns a reference to this Projection as [Perspective] if it is in fact a Perspective projection. Otherwise, None is returned.

pub fn as_perspective_mut(&mut self) -> Option<&mut Perspective>

Returns a mutable reference to this Projection as [Perspective] if it is in fact a Perspective projection. Otherwise, None is returned.

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

Returns a reference to the inner matrix represpentation of this projection.

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

Returns a mutable reference to the inner matrix represpentation of this projection.

pub fn screen_to_world(
    &self,
    screen_position: Point2<f32>,
    screen_diagonal: Vector2<f32>,
    camera_transform: &Transform
) -> Point3<f32>

Transforms position from screen space to camera space

pub fn world_to_screen(
    &self,
    world_position: Point3<f32>,
    screen_diagonal: Vector2<f32>,
    camera_transform: &Transform
) -> Point2<f32>

Translate from world coordinates to screen coordinates
