Struct LightDescriptor

#[repr(C)]
pub struct LightDescriptor {
    pub light_type: LightStyle,
    pub index: u32,
    pub transform_id: Id<TransformDescriptor>,
    pub shadow_map_desc_id: Id<ShadowMapDescriptor>,
}

A generic light that is used as a slab pointer to a specific light type.

Fields

light_type: LightStyle

The type of the light

index: u32

The index of the light in the lighting slab

transform_id: Id<TransformDescriptor>

The id of a transform to apply to the position and direction of the light.

This Id points to a transform on the lighting slab.

The value of this descriptor can be synchronized with that of a node transform on the geometry slab from crate::light::AnalyticalLight::link_node_transform.

shadow_map_desc_id: Id<ShadowMapDescriptor>

The id of the shadow map in use by this light.

Implementations

impl LightDescriptor

pub fn into_directional_id(self) -> Id<DirectionalLightDescriptor>

pub fn into_spot_id(self) -> Id<SpotLightDescriptor>

pub fn into_point_id(self) -> Id<PointLightDescriptor>

Trait Implementations

impl Clone for LightDescriptor

fn clone(&self) -> LightDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LightDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LightDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl From<Id<DirectionalLightDescriptor>> for LightDescriptor

fn from(id: Id<DirectionalLightDescriptor>) -> Self

Converts to this type from the input type.

impl From<Id<PointLightDescriptor>> for LightDescriptor

fn from(id: Id<PointLightDescriptor>) -> Self

Converts to this type from the input type.

impl From<Id<SpotLightDescriptor>> for LightDescriptor

fn from(id: Id<SpotLightDescriptor>) -> Self

Converts to this type from the input type.

impl PartialEq for LightDescriptor

fn eq(&self, other: &LightDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SlabItem for LightDescriptor

where LightStyle: SlabItem, u32: SlabItem, Id<TransformDescriptor>: SlabItem, Id<ShadowMapDescriptor>: SlabItem,

const SLAB_SIZE: usize = 4usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.

impl Copy for LightDescriptor
