Fields

id: u64

Unique identifier for this item.

transform: Mat4

World transform.

mesh_handle: u64

Mesh/geometry handle (opaque).

material_index: u32

Material index into the material library.

sort_key: MaterialSortKey

Material sort key for batching.

camera_distance: f32

Distance from camera (computed during sorting).

bucket: RenderBucket

Which bucket this item belongs to.

visible: bool

Whether this item is visible (frustum culling result).

bounds_center: [f32; 3]

Bounding sphere center (world space).

bounds_radius: f32

Bounding sphere radius.

instance_count: u32

Instance count (for instanced rendering, 1 = no instancing).

instance_buffer: u64

Instance data buffer handle (if instanced).

vertex_count: u32

Vertex count (for stats).

index_count: u32

Index count (for stats).

alpha_test: bool

Whether this item uses alpha testing (cutout).

two_sided: bool

Whether this item is two-sided (no backface culling).
