Struct TileBatch 

pub struct TileBatch {
    pub vertex_buffer: Buffer,
    pub index_buffer: Buffer,
    pub index_count: u32,
}

GPU buffers for all flat tile quads that share a single atlas page.

Produced by build_tile_batches and consumed by WgpuMapRenderer::render_tile_batches. One draw call per non-None batch.

Fields

vertex_buffer: Buffer

Merged vertex buffer (4 TileVertex per tile).

index_buffer: Buffer

Merged index buffer (6 u32 indices per tile).

index_count: u32

Total number of indices to draw.
