Typedef Documentation

std::vector< PcpSiteTrackerSegment > PcpSiteTracker

Represents a single path through the composition tree.

As the tree is being built, we add segments to the tracker. If we encounter a site that we've already visited, we've found a cycle.

Definition at line 130 of file types.h.

PcpVariantFallbackMap

typedef std::map<std::string, std::vector<std::string>> PcpVariantFallbackMap

A "map of lists" of fallbacks to attempt to use when evaluating variant sets that lack an authored selection.

This maps a name of a variant set (ex: "shadingComplexity") to a ordered list of variant selection names. If there is no variant selection in scene description, Pcp will check for each listed fallback in sequence, using the first one that exists.

Definition at line 188 of file types.h.

Enumeration Type Documentation

enum PcpArcType

Describes the type of arc connecting two nodes in the prim index.

Definition at line 46 of file types.h.

Function Documentation

bool PcpIsClassBasedArc ( PcpArcType  arcType )

inline

Returns true if arcType represents a class-based composition arc, false otherwise.

The key characteristic of these arcs is that they imply additional sources of opinions outside of the site where the arc is introduced.

Definition at line 111 of file types.h.

bool PcpIsInheritArc ( PcpArcType  arcType )

inline

Returns true if arcType represents an inherit arc, false otherwise.

Definition at line 91 of file types.h.

bool PcpIsSpecializeArc ( PcpArcType  arcType )

inline

Returns true if arcType represents a specialize arc, false otherwise.

Definition at line 99 of file types.h.

Variable Documentation

size_t PCP_INVALID_INDEX = unspecified

A value which indicates an invalid index.

This is simply used inplace of either -1 or numeric_limits::max() (which are equivalent for size_t). for better clarity.
