Module visibility

Structs

• InheritedVisibility
  Whether or not an entity is visible in the hierarchy. This will not be accurate until VisibilityPropagate runs in the PostUpdate schedule.
• NoFrustumCulling
  Use this component to opt-out of built-in frustum culling for entities, see Frustum.
• RenderLayers
  Describes which rendering layers an entity belongs to.
• RenderVisibilityRanges
  Stores information related to VisibilityRanges in the render world.
• ViewVisibility
  Algorithmically-computed indication of whether an entity is visible and should be extracted for rendering.
• VisibilityBundle
  A Bundle of the Visibility, InheritedVisibility, and ViewVisibility Components, which describe the visibility of an entity.
• VisibilityPlugin
• VisibilityRange
  Specifies the range of distances that this entity must be from the camera in order to be rendered.
• VisibilityRangePlugin
  A plugin that enables VisibilityRanges, which allow entities to be hidden or shown based on distance to the camera.
• VisibleEntities
  Collection of entities visible from the current view.
• VisibleEntityRanges
  Stores which entities are in within the VisibilityRanges of views.

Enums

• Visibility
  User indication of whether an entity is visible. Propagates down the entity hierarchy.
• VisibilitySystems

Constants

• DEFAULT_LAYERS
• VISIBILITY_RANGES_STORAGE_BUFFER_COUNT
  We need at least 4 storage buffer bindings available to enable the visibility range buffer.

Functions

• calculate_bounds
  Computes and adds an Aabb component to entities with a Handle<Mesh> component and without a NoFrustumCulling component.
• check_visibility
  System updating the visibility of entities each frame.
• check_visibility_ranges
  Checks all entities against all views in order to determine which entities with VisibilityRanges are potentially visible.
• extract_visibility_ranges
  Extracts all VisibilityRange components from the main world to the render world and inserts them into RenderVisibilityRanges.
• update_frusta
  Updates Frustum.
• write_render_visibility_ranges
  Writes the RenderVisibilityRanges table to the GPU.

Type Aliases

• Layer
  An identifier for a rendering layer.
• WithMesh
  A convenient alias for With<Handle<Mesh>>, for use with VisibleEntities.
