IModelJson.IndexedMeshProps Interface
Interface for an indexed mesh.
- IMPORTANT: All indices are one-based.
- i.e. vertex index given as 11 appears at index 10 in the data array.
- This is to allow a negated index to mean "don't draw the following edge"
- Although negative indices are not allowed for normalIndex, colorIndex, or paramIndex, the "one based" style is used for them so that all indices within the indexedMesh json object are handled similarly.
- In all index arrays, a ZERO indicates "end of facet".
