PickId

viewport_lib::renderer

Struct PickId 

Source 
pub struct PickId(pub u64);
Expand description

Typed GPU pick identifier for a renderable surface.

The renderer includes a surface in the GPU pick pass only when its pick_id is not PickId::NONE. Helper geometry, transient previews, and any surface that should be invisible to clicks should use PickId::NONE (the default).

Application code owns pick identity: IDs do not need to come from the scene graph. Any nonzero u64 that the application can map back to a domain object is a valid PickId.

Implementations§

Source§

impl PickId

Source

pub const NONE: Self

Sentinel value meaning “not pickable”.

Surfaces with pick_id == PickId::NONE are excluded from the GPU pick pass. This is the default value for SceneRenderItem::pick_id.
