  1. introduction to omegalib and omicron Alessandro Febretti Electronic Visualization Lab – University of Illinois at Chicago

  2. omicron vsomegalib omicronConnector.h Input device Tcp / Udp omicron input server user application Input device • omicron: input management library • Can be integrated directly as library or used as input server

  3. omicronConnector example #include <connector/omicronConnectorClient.h> using namespaceomicronConnector; int main(intargc, char** argv) { OmicronConnectorClient<ConnectorListener> client; client.connect("127.0.0.1"); while(true) client.poll(); } classConnectorListener { public: static voidonEvent(constEventData& e) { printf(“Received event!\n”); } };

  4. omicron events • omicron events designed as generic input data containers • information about event source • service class (wand, gamepad, pointer, ui) • Services of same class have similar event generation semantics • event type, position, orientation, binary flags • variable length extra data • can be float array, vector3 array, generic char* • more information: http://code.google.com/p/omicron-sdk/wiki/EventReference

  5. omicron event services • event service = source of omicron events • some built-in event services: • VRPN-supported trackers • Optitrack native • XBox360, PS3, Wiimote controllers • PQLabs touch overlays • Kinect skeletons • ThinkGear • iPad app (prototype) • SAGE Pointer

  6. omicron utilities • omicron also offers utility APIs for app developers (used by omegalib) • config file support (libconfig) • xml reading/writing (tinyxml) • multithreading (tinythreads) • tcp client/server API (asio) • math library (Eigen)

  7. user application graphics frontend omegalib core omicron Equalizer VR toolkit built on top of omicron (input) and Equalizer (display)

  8. omegalib core = support backend for different graphics frontends Currently supported frontends: OpenSceneGraph Vtk Plain OpenGL

  9. some legacy applications can be ported to omegalib (https://code.google.com/p/omegadoom/)

  10. Research direction: multi-application VR • run multiple applications inside separate viewports / windows (a la SAGE) • Allow applications to switch to ‘fullscreen mode’ and take over entire display • Challenges: • Load balancing (equalizer helps a bit) • Interaction

  11. That’s all folks! • Links: • omicron: http://code.google.com/p/omicron-sdk/ • omegalib: https://code.google.com/p/omegalib/ • Equalizer: http://www.equalizergraphics.com/
