Struct PointLight 

pub struct PointLight(/* private fields */);

A light from a point (WinUI Microsoft.UI.Composition.PointLight): a point of a visual is lit by the cosine of the angle of the light to the visual, weakened by the attenuation of the distance 1 / (constant + linear * d + quadratic * d^2) between the minimum and the maximum cutoff. Every member but CoordinateSpace is animatable.

Implementations

impl PointLight

pub fn from_light(light: &Rc<CompositionLight>) -> Option<PointLight>

The handle of light as this class, if it is one.

pub fn props(&self) -> &PointLightProps

The generated properties of the class.

impl PointLight

pub fn color(&self) -> Color

The colour of the light (default white).

pub fn set_color(&self, value: Color)

pub fn constant_attenuation(&self) -> f32

The constant term of the attenuation (default 1).

pub fn set_constant_attenuation(&self, value: f32)

pub fn linear_attenuation(&self) -> f32

The term of the attenuation proportional to the distance (default 0).

pub fn set_linear_attenuation(&self, value: f32)

pub fn quadratic_attenuation(&self) -> f32

The term of the attenuation proportional to the square of the distance (default 0).

pub fn set_quadratic_attenuation(&self, value: f32)

pub fn coordinate_space(&self) -> Option<Rc<CompositionVisual>>

The visual whose coordinates Offset is in; None for the targeted visual.

pub fn set_coordinate_space(&self, value: Option<Rc<CompositionVisual>>)

pub fn offset(&self) -> Vector3D

The position of the light in its coordinate space; Z is the height above the visuals.

pub fn set_offset(&self, value: Vector3D)

pub fn intensity(&self) -> f32

The intensity of the light (default 1).

pub fn set_intensity(&self, value: f32)

pub fn min_attenuation_cutoff(&self) -> f32

The distance up to which the light is not attenuated (default 0).

pub fn set_min_attenuation_cutoff(&self, value: f32)

pub fn max_attenuation_cutoff(&self) -> f32

The distance beyond which the light lights nothing (default f32::MAX).

pub fn set_max_attenuation_cutoff(&self, value: f32)
