Struct PbrSsboTransformRegistry 

pub struct PbrSsboTransformRegistry {
    pub entity_to_transform: HashMap<Entity, u32>,
    pub available_transform_ids: Vec<u32>,
    pub next_transform_id: u32,
    pub dirty_transforms: Vec<(u32, TransformUniform)>,
}

Resource to track the mapping between entities and their transform IDs in the SSBO, as well as the list of dirty transforms that need to be updated in the SSBO. This is used to update the PbrSsboTransform with the new transforms of the entities with a PBR material.

Fields

entity_to_transform: HashMap<Entity, u32>

available_transform_ids: Vec<u32>

next_transform_id: u32

dirty_transforms: Vec<(u32, TransformUniform)>

Implementations

impl PbrSsboTransformRegistry

pub fn add_entity(&mut self, entity: Entity, transform: GlobalTransform) -> u32

Register an entity with its transform in the registry, returning the assigned transform ID in the SSBO. If the entity is already registered, returns the existing transform ID.

pub fn get_transform_id(&self, entity: Entity) -> Option<u32>

Get the transform ID of an entity in the registry, if it exists.

pub fn update_entity(&mut self, entity: Entity, transform: GlobalTransform)

Update the transform of an entity in the registry, marking it as dirty for the next SSBO update. If the entity is not registered, it will be added to the registry.

pub fn remove_entity(&mut self, entity: Entity)

Unregister an entity from the registry, freeing its transform ID for future use.
