Fields

product_id: u32

geometry_item_id: u32

tex_coords: Vec<[f64; 2]>

Source IFC bottom-left texture coordinates, before mesher seam expansion.

tex_coord_index: Vec<[u32; 3]>

1-based, parallel to source CoordIndex (before winding correction).

source_indices: Vec<u32>

Actual final source topology after canonical placement and welding.

target_indices: Vec<u32>

Final canonical target topology; becomes provenance after Apply.

target_vertex_count: usize

Canonical target vertex pool size; removed degenerate triangles can leave unused vertices, so the maximum index is not bounded by corner count.

preview_corner_uvs: Vec<f32>

UV pairs in triangle-corner order, with GPU V flip. Fragment consumers remap canonical corner slots and expand seams without moving geometry.

target_corner_normals: Vec<f32>

Final canonical shading normals in triangle-corner order, converted from IFC Z-up to renderer Y-up as [nx, nz, -ny], matching MeshDataJs. UV-dependent welding may choose a different normal representative.
