Abstract: A hybrid method or apparatus for processing OpenGL display list commands. A deamon intercepts display list commands issued by a client to an OpenGL stack. Responsive to a newList [list commands] endList sequence: the daemon stores a representation of a first subset of the list commands; and creates, in the stack, a display list corresponding to a second subset of the list commands. Responsive to a callList command: the daemon issues to the stack at least one immediate mode command corresponding to the first subset of the list commands and at least one callList command invoking the display list corresponding to the second subset of the list commands. The daemon may also store a representation of an expression or function. Responsive to the callList command, the daemon may evaluate the expression or function and conditionally change the step of invoking the display list based on the outcome.

Abstract: A modified display list contains a series of n nested bounding volumes. The first bounding volume in the series contains the remaining n-1 bounding volumes the series. The second bounding volume contains the remaining n-2 bounding volumes in the series, and so on. Upon invocation, the graphics display system processes the modified list sequentially and tests the bounding volumes as they are encountered. As soon as a bounding volume is encountered whose coordinates define a region that should not be rendered, further sequential processing of rendering commands in the list may be halted. If any state commands remain in the list, those commands or an equivalent set of state commands may be executed, and then processing of the list is complete. Alternatively, if push/pop state commands exist on either side of the list, then processing of the list may be halted without more.

Abstract translation: 修改的显示列表包含一系列嵌套的嵌套卷。 系列中的第一个包围卷包含剩余的n-1个界限卷。 第二个界限卷包含系列中剩余的n-2个界限卷，依此类推。 在调用时，图形显示系统按顺序处理修改的列表，并在遇到遇到的范围内测试边界卷。 一旦遇到其坐标定义不应该呈现的区域的边界体积，则可能停止列表中渲染命令的进一步顺序处理。 如果列表中有任何状态命令，则可以执行这些命令或等效的状态命令集，然后完成列表的处理。 或者，如果在列表的任一侧上存在push / pop状态命令，则可以停止列表的处理。

Abstract: A memory management system and method that quickly allocates and reuses memory for storage of data, such as display lists in a graphics system. The memory manager allocates memory without information regarding the amount of memory that is to be required while minimizing system-level memory allocation calls and maximizing the contiguity of the allocated memory which is used. The memory manager acquires from system memory a memory block that is of a predetermined size that is significantly larger than the anticipated memory size required to store a display list. The memory manager allocates to the display list that portion of the acquired memory block necessary for storing the display list, maintaining control over the unused portion of the acquired memory in a memory pool of available memory for future allocation to another display list without performing subsequent system-level calls.

Abstract: A system for buffering data received from a network comprises a network socket, a plurality of buffers, a buffer pointer pool, receive logic, and packet delivery logic. The buffer pointer pool has a plurality of entries respectively pointing to the buffers. The receive logic is configured to pull an entry from the pool and to perform a bulk read of the network socket. The entry points to one of the buffers, and the receive logic is further configured to store data from the bulk read to the one buffer based on the entry. The packet delivery logic is configured to read, based on the entry, the one buffer and to locate a missing packet sequence in response to a determination, by the packet delivery logic, that the one buffer is storing an incomplete packet sequence. The packet delivery logic is further configured to form a complete packet sequence based on the incomplete packet sequence and the missing packet sequence.

Abstract: An apparatus for transmitting to a network comprises a queue, packetization logic, interface logic, and queue logic. The packetization logic is configured to packetize data into a plurality of data packets and to store, to the queue, entries pointing to the data packets. The interface logic is configured to read the entries from the queue. The interface logic, for each of the read entries, is configured to retrieve one of the packets pointed to by the read entry and to transmit the retrieved packet to a network socket. The queue logic is configured to limit, based on a number of retransmission requests detected by the queue logic, a number of entries that the packetization logic may store to the queue during a particular time period thereby controlling a transmission rate of the apparatus.
