“…Thus, a better approach is to use active pixel encoding, which classifies the pixels as either active or inactive and provides run lengths for continuous regions of any active pixels. Moreland et al [16] show that this encoding is both effective and never adds to the data size even in the worst pathological cases. Active pixel encoding improves on region boxes by tightly identifying active and inactive pixels.…”

The only proven method for performing distributed-memory parallel rendering at large scales, tens of thousands of nodes, is a class of algorithms called sort last. The fundamental operation of sort-last parallel rendering is an image composite, which combines a collection of images generated independently on each node into a single blended image. Over the years numerous image compositing algorithms have been proposed as well as several enhancements and rendering modes to these core algorithms. However, the testing of these image compositing algorithms has been with an arbitrary set of enhancements, if any are applied at all. In this paper we take a leading production-quality imagecompositing framework, IceT, and use it as a testing framework for the leading image compositing algorithms of today. As we scale IceT to ever increasing job sizes, we consider the image compositing systems holistically, incorporate numerous optimizations, and discover several improvements to the process never considered before. We conclude by demonstrating our solution on 64K cores of the Intrepid BlueGene/P at Argonne National Laboratories.

“…This scheme corresponds to the render server system, where rendering is provided as a distant shared resource. By using existing image composing tools [14,20] we can use several servers in parallel for increased performance.…”

“…Each host can render the pixels it displays, or it can render pixels to be displayed by different hosts. In this case pixels have to be communicated on the network and recomposed to form the final images [20]. This scheme is usually called a sort-last approach [18].…”

Existing parallel or remote rendering solutions rely on communicating pixels, OpenGL commands, scene-graph changes or application-specific data. We propose an intermediate solution based on a set of independent graphics primitives that use hardware shaders to specify their visual appearance. Compared to an OpenGL based approach, it reduces the complexity of the model by eliminating most fixed function parameters while giving access to the latest functionalities of graphics cards. It also suppresses the OpenGL state machine that creates data dependencies making primitive re-scheduling difficult.Using a retained-mode communication protocol transmitting changes between each frame, combined with the possibility to use shaders to implement interactive data processing operations instead of sending final colors and geometry, we are able to optimize the network load. High level information such as bounding volumes is used to setup advanced schemes where primitives are issued in parallel, routed according to their visibility, merged and re-ordered when received for rendering. Different optimization algorithms can be efficiently implemented, saving network bandwidth or reducing texture switches for instance.We present performance results based on two VTK applications, a parallel iso-surface extraction and a parallel volume renderer. We compare our approach with Chromium. Results show that our approach leads to significantly better performance and scalability, while offering easy access to hardware accelerated rendering algorithms.

iii Στο όγδοο κεφάλαιο παρουσιάζονται τα συμπεράσματα της διδακτορικής διατριβής, με μία συνολική αποτίμηση τόσο της μεθοδολογίας όσο και της υλοποίησης των επιμέρους στοιχείων. Η διατριβή καταλήγει με εκτενή παρουσίαση των δυνατοτήτων επέκτασης του συστήματος.Συμπερασματικά, η διατριβή προτείνει μια γενικευμένη μεθοδολογία μοντελοποίησης αντικειμένων που συναντώνται κατά την ανάλυση συστημάτων κατεργασιών, με έμφαση στον ρόλο του χρήστη εντός ενός εικονικού περιβάλλοντος . Η μεθοδολογία κάνει χρήση διαφορετικών εργαλείων για την δημιουργία του εικονικού κόσμου και την επίλυση προβλημάτων που προκύπτουν κατά την εικονοποίηση λειτουργικών αντικειμένων και την μεταξύ τους αλληλεπίδραση· τα σημασιολογικά μοντέλα προσφέρουν τον απαιτούμενο φορμαλισμό, οι κινηματικοί αλγόριθμοι ενισχύουν την λειτουργικότητα των αντικειμένων, η ανίχνευση συγκρούσεων υποδεικνύει στον χρήστη προβλήματα μεταξύ των αντικειμένων, τα δίκτυα Petri καλύπτουν τον τομέα συγχρονισμού των αντικειμένων. Συνολικά, η πιλοτική υλοποίηση ισορροπεί ανάμεσα στην αυτοματοποίηση διαδικασιών και στην ελευθερία επιλογών του χρήστη. Ταυτόχρονα, αποτελεί μια ικανή βάση για περαιτέρω επεκτάσεις είτε μέσω προσθήκης αντικειμένων είτε μέσω διεύρυνσης της εμβύθισης του χρήστη, αλλά και την συμμετοχή περισσοτέρων χρηστών ταυτόχρονα.
