Struct Lightmap

Source
pub struct Lightmap {
    pub map: FxHashMap<Handle<Node>, Vec<LightmapEntry>>,
    pub patches: FxHashMap<u64, SurfaceDataPatchWrapper>,
}
Expand description

Lightmap is a texture with precomputed lighting.

Fields§

§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§

Source§

impl Lightmap

Source

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

Source§

impl Lightmap

Source

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

Loads a light map from the given path.

Source

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.

Source

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.

Source

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

Saves lightmap textures into specified folder.
