Struct MeshTextureData 

pub struct MeshTextureData {
    pub texture_id: u32,
    pub rgba: Option<Arc<Vec<u8>>>,
    pub width: u32,
    pub height: u32,
    pub url: Option<String>,
    pub repeat_s: bool,
    pub repeat_t: bool,
}

A surface texture attached to a mesh (issues #961, #1781). Exactly one of rgba / url is set:

• rgba: decoded in Rust (IfcBlobTexture PNG / IfcPixelTexture raw); the browser only uploads it to a GPU texture — no image logic in TS.
• url: an IfcImageTexture reference (#1781) the HOST layer resolves — typically a sibling image file inside the .ifcZIP container. Real files share one multi-megapixel image across dozens of face sets, so the pipeline ships the reference, never per-mesh pixels.

Fields

texture_id: u32

Express id of the source IfcSurfaceTexture — the stable dedup key: every mesh sampling the same image carries the same id, so consumers create ONE GPU texture per id, not one per mesh. 0 in legacy payloads.

rgba: Option<Arc<Vec<u8>>>

width * height * 4 bytes, row-major, top-down, straight alpha. Arc-shared across meshes; None for an external image reference.

width: u32

height: u32

url: Option<String>

IfcImageTexture.URLReference verbatim (#1781); None for decoded.

repeat_s: bool

Sampler wrap from IfcSurfaceTexture.RepeatS/RepeatT.

repeat_t: bool
