UvPlacement

Remarks

⚠ A transform rather than coordinates, so that a caller can pack twice and compare. A packer that rewrote the coordinates in place would make "what did this setting cost me" a question you answer by re-running the whole unwrap. It also keeps the island's own shape exactly as it arrived, which is docs/plan/42's exit criterion 7 — repacking an artist's layout must leave the island shapes untouched.

Fields and properties (5)

• public int Island

  Which island, by index into what was handed in.

• public Vector2 Offset

  Where the island's lower corner sits, in the atlas's unit square.

• public float Scale

  What the island's coordinates were multiplied by.

• public int Rotation

  Quarter turns applied, counter-clockwise, before the offset.

• public Int2 Tile

  Which UDIM tile, as integer offsets. (0, 0) for a single-atlas pack.

Methods (2)

• public UvPlacement(int Island, Vector2 Offset, float Scale, int Rotation, Int2 Tile)

  Where the packer put an island, as a transform rather than as rewritten coordinates.

• public Vector2 Apply(in UvIsland island, Vector2 coordinate)

  Where one of the island's coordinates ends up.
