All GsNode's locally owned by only one GsModel, so GsNode metafiles is also owned by GsModel. GsModel could be shared
|
between different rendering modules. But viewportId is creating from SlotManager owned by rendering device, so
|
viewportId's for different devices will lie in same range, so couldn't be used as unique view identifier inside
|
GsModel. To solve problem we create for each GsModel their own SlotManager which is used for generate unique
|
viewportId for each view referenced by GsModel. This localViewportId is stored on GsModel side, view access to it
|
and store it's own copy localViewportId for optimization purposes (this is not problem for MT because only one
|
GsModel is used per parallel vectorization.
