Struct VItemsBuffer 

pub struct VItemsBuffer { /* private fields */ }

Merged GPU buffers for all VItems in a frame.

Instead of one set of buffers per VItem, all data is packed into contiguous arrays with an index table (item_infos) that tells shaders where each item’s data lives.

Implementations

impl VItemsBuffer

pub fn new(ctx: &WgpuContext) -> Self

pub fn update(&mut self, ctx: &WgpuContext, vitems: &[VItem])

Pack all VItems into the merged buffers. Called once per frame.

pub fn item_count(&self) -> u32

pub fn total_points(&self) -> u32

pub fn compute_bind_group_layout(ctx: &WgpuContext) -> BindGroupLayout

pub fn render_bind_group_layout(ctx: &WgpuContext) -> BindGroupLayout
