Properties

Name	Type	Description
`source`	`FieldSource`	The baked field. Shared by reference: it does not move and it is the large thing.
`transform`readonly	`Float32Array`	World from object, copied at the moment it was declared. Uniform scale only.
`albedo`readonly	`Float32Array`	What colour this placement's surface is, copied like the transform. White where none was given. More A ray that lands on a wall needs to know what colour it is, because what leaves a surface is the light arriving times its albedo — and a composed distance field is a union that has already forgotten which instance won. `demo/dev/bounce.html` is what made it necessary: a trace without it returned the same answer for a red wall and a white one. On the placement rather than the field, because the same baked shape is placed many times and two pillars cut from one mould may be painted differently.
