47 // FVarLevel:
48 // A "face-varying channel" includes the topology for a set of face-varying
49 // data, relative to the topology of the Level with which it is associated.
50 //
51 // Analogous to a set of vertices and face-vertices that define the topology for
52 // the geometry, a channel requires a set of "values" and "face-values". The
53 // "values" are indices of entries in a set of face-varying data, just as vertices
54 // are indices into a set of vertex data. The face-values identify a value for
55 // each vertex of the face, and so define topology for the values that may be
56 // unique to each channel.
57 //
58 // In addition to the value size and the vector of face-values (which matches the
59 // size of the geometry's face-vertices), tags are associated with each component
60 // to identify deviations of the face-varying topology from the vertex topology.
61 // And since there may be a one-to-many mapping between vertices and face-varying
62 // values, that mapping is also allocated.
63 //
64 // It turns out that the mapping used is able to completely encode the set of
65 // face-values and is more amenable to refinement. Currently the face-values
66 // take up almost half the memory of this representation, so if memory does
67 // become a concern, we do not need to store them. The only reason we do so now
68 // is that the face-value interface for specifying base topology and inspecting
69 // subsequent levels is very familiar to that of face-vertices for clients. So
70 // having them available for such access is convenient.
71 //
72 // Regarding scope and access...
73 // Unclear at this early state, but leaning towards nesting this class within
74 // Level, given the intimate dependency between the two.
75 // Everything is being declared public for now to facilitate access until it's
76 // clearer how this functionality will be provided.
