struct	reusex::visualize::SceneLayer
	The actors one layer added, so an interactive viewer can toggle it. More...
struct	reusex::visualize::SceneInfo
	What populate_scene() added. More...
struct	reusex::visualize::CutPlane

Functions
const LabelPalette &	reusex::visualize::default_label_palette ()
	The tokens' scale (see LabelPalette).
int	reusex::visualize::label_palette_slot (std::uint32_t label, std::size_t size)
	Palette slot of a point label: (label - 1) % size; kUnlabeledSlot for label 0 or an empty palette; kInvalidSlot for an out-of-contract label (a wrapped -1), which must not borrow a class's colour.
std::array< std::uint8_t, 3 >	reusex::visualize::label_palette_color (const LabelPalette &palette, std::uint32_t label)
	The colour of label in palette.
std::string_view	reusex::visualize::to_string (LodMethod method)
std::vector< std::uint32_t >	reusex::visualize::lod_indices (std::size_t total, std::size_t budget, std::string_view storage_order, LodMethod *method=nullptr)
	Which of total stored points to draw within a budget of budget.
SceneInfo	reusex::visualize::populate_scene (vtkRenderer *renderer, const ProjectDB &db, const SceneOptions &opts)
	Load opts' layers from db and add them to renderer.
CutPlane	reusex::visualize::resolve_cut_plane (const ProjectDB &db, const SceneBounds &bounds, std::optional< double > height)
	Decide where to cut bounds: height (or the default) above the floor detected by rux create planes, or above the bounding box's lower face.
void	reusex::visualize::apply_cut_plane (vtkRenderer *renderer, double z)
	Clip every actor of renderer to the half-space below z = z.
void	reusex::visualize::clear_cut_planes (vtkRenderer *renderer)
	Remove every clipping plane from renderer's actors.
void	reusex::visualize::place_preset_camera (vtkRenderer *renderer, const CameraFraming &framing, const SceneBounds &bounds)
	Place renderer's active camera for a preset view of bounds.
void	reusex::visualize::place_explicit_camera (vtkRenderer *renderer, const CameraSpec &spec, int width, int height, const SceneBounds &bounds)
	Place renderer's active camera at an explicit pose + pinhole camera, for an image of width x height pixels.
void	reusex::visualize::install_vtk_log_bridge ()
	Route VTK's diagnostics into ReUseX logging, once per process (see render_view()).

Variables
constexpr int	reusex::visualize::kUnlabeledSlot = -1
	Sentinel slots of label_palette_slot().
constexpr int	reusex::visualize::kInvalidSlot = -2
