| Operation | complex128 | struct |
|---|---|---|
| New vector | pixel.V(x, y) | pixel.Vec{X: x, Y: y} or pixel.V(x, y) |
| Get coord | u.X() | u.X |
| Set coord | u = u.WithX(x) | u.X = x |
| Add to coord | u += pixel.X(x) | u.X += x |
| Mul coord | u = u.ScaledXY(pixel.V(c, 1)) | u.X *= c |
| Add vectors | u + v | u.Add(v) |
| Scale vector | u = u.Scaled(c) | u = u.Scaled(c) |
| Mul vectors | u = u.ScaledXY(v) | u = u.ScaledXY(v) |
