Burn-grid helpers: per-vertex power UVs for a stock mesh.

Functions

compute_power_uvs()

compute_power_uvs(
    positions: numpy.NDArray[numpy.float32],
    origin_mm: tuple[float, float],
    px_per_mm: tuple[float, float],
    size_px: tuple[int, int],
) -> numpy.NDArray[numpy.float32]

Map vertex positions onto a burn power grid as UVs.

Parameter	Type	Description
positions	numpy.NDArray[numpy.float32]	Flat mesh vertex positions, shape (N, 3).
origin_mm	tuple[float, float]	World-mm coordinate of the grid's (0, 0) pixel corner.
px_per_mm	tuple[float, float]	Grid density in pixels per millimetre.
size_px	tuple[int, int]	Grid size in pixels (width, height).
Returns	numpy.NDArray[numpy.float32]	(N, 2) power UVs index-aligned with positions.
