A binning architecture that allows opaque and transparent primitives to be segregated automatically into pairs of bins covering the same bin rectangle on the screen. When the frame is complete, the opaque bin will be rendered first and then the transparent bin will be rendered repeatedly using the depth peeling algorithm until all the layers have been resolved. This will happen automatically without requiring the application to isolate and store the transparent primitives until all of the opaque primitives have been rendered or submit the transparent primitives repeated until all of the transparent layers have been resolved.

Redundant changes of tracked state issued by an application are filtered out by comparing the new state value with the old value, and if they are the same, no update is made. State changes are collected in on-chip memory and added to the bin if the state vector associated with the bin is out of date. State changes within a bin are done incrementally in temporal order, and a bin is only brought up to date prior to adding in a new primitive if the state has changed since the last primitive was added to it.

Conflicts between the database-building and traversal phases are resolved by allowing the database bin size to be different from the display bin size. The database bin size is some multiple of the bin display bin size, and when there are multiple display bins in a database bin, each database bin is traversed multiple times for display, and the rasterizer discards primitives outside of the current display bin. This allows a trade off between memory bandwidth consumed for database building and bandwidth consumed for display, particularly when the display traversal is done multiple of times.
