Detailed Description

An IFF chunk containing information about adjacent indices.

An optional chunk of adjacent indices always refers to an existing index buffer, and contains exactly the same number of individual entries, stored as an UInt32 array. Adjacency information is only supported for index buffers of type IEnums::PRIMITIVE_TYPE_TRIANGLES. Every three consecutive indices in the referenced index buffer define a single triangle, with edges 0-1, 1-2 and 2-0. The AdjacentIndicesChunk stores the position of the corresponding edge of the neighboring triangle within the index buffer, or 0xffffffff if no neighboring triangle exists.
