Struct Lightmap 

pub struct Lightmap {
    pub texture_name: String,
    pub second_tex_coord_location: u8,
    pub map: FxHashMap<Handle<Node>, Vec<LightmapEntry>>,
    pub patches: FxHashMap<u64, SurfaceDataPatchWrapper>,
}

Lightmap is a texture with precomputed lighting.

Fields

texture_name: String

Name of the property this light map is bound to in all materials across all surfaces for which the light map was generated.

second_tex_coord_location: u8

Location of the second texture coordinate attribute in the vertex buffer of all surfaces.

map: FxHashMap<Handle<Node>, Vec<LightmapEntry>>

Node handle to lightmap mapping. It is used to quickly get information about lightmaps for any node in scene.

patches: FxHashMap<u64, SurfaceDataPatchWrapper>

List of surface data patches. Each patch will be applied to corresponding surface data on resolve stage.

Implementations

impl Lightmap

pub const TEXTURE_NAME: &'static str = "texture_name"

pub const SECOND_TEX_COORD_LOCATION: &'static str = "second_tex_coord_location"

pub const MAP: &'static str = "map"

impl Lightmap

pub async fn load<P: AsRef<Path>>( path: P, resource_manager: ResourceManager, ) -> Result<Lightmap, VisitError>

Loads a light map from the given path.

pub fn save<P: AsRef<Path>>(&mut self, path: P) -> VisitResult

Saves a light map to the given file. Keep in mind, that the textures should be saved separately first, via Self::save_textures method.

pub fn new( data: LightmapInputData, texels_per_unit: u32, uv_spacing: f32, cancellation_token: CancellationToken, progress_indicator: ProgressIndicator, ) -> Result<Self, LightmapGenerationError>

Generates lightmap for given scene. This method automatically generates secondary texture coordinates! This method is blocking, however internally it uses massive parallelism to use all available CPU power efficiently.

texels_per_unit defines resolution of lightmap, the higher value is, the more quality lightmap will be generated, but also it will be slow to generate. progress_indicator allows you to get info about current progress. cancellation_token allows you to stop generation in any time.

pub fn save_textures<P: AsRef<Path>>( &self, base_path: P, resource_manager: ResourceManager, ) -> Result<(), ResourceRegistrationError>

Saves lightmap textures into specified folder.

Trait Implementations

impl Clone for Lightmap

fn clone(&self) -> Lightmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lightmap

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

Formats the value using the given formatter.

impl Default for Lightmap

fn default() -> Self

Returns the “default value” for a type.

impl Reflect for Lightmap

where Self: 'static,

fn source_path() -> &'static str

fn try_clone_box(&self) -> Option<Box<dyn Reflect>>

fn type_name(&self) -> &'static str

fn derived_types() -> &'static [TypeId]

fn query_derived_types(&self) -> &'static [TypeId]

fn doc(&self) -> &'static str

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly.
