Properties

Name	Type	Description
`source`readonly	`FieldSource`
`albedo`readonlyoptional	`Vec3`	What colour this instance's surface is, or white where it did not say. More On the instance rather than the source, because the same baked field is placed many times and two pillars cut from one mould may be painted differently. Optional so that every caller written before the trace needed a colour is unchanged.
`transform`readonly	`ReadonlyMat4`	World from object. More Uniform scale only, and `composeGlobalField` refuses the rest rather than approximating. A distance is not preserved by a non-uniform scale: the factor to correct by depends on the direction to the nearest surface, which is exactly what a distance field does not record. An instance squashed on one axis and sampled anyway produces something that is a distance in no direction and looks like one in every slice.
