gled

Classes are added to Gled in shared libraries, called libsets, which are loaded at run time. Each libset brings its classes together with their GUI views, their OpenGL renderers and its demo macros. The framework itself, the server and the GUI are the GledCore libset.

Each libset has a fixed LibID; together with the class IDs within the libset it identifies classes in streams and method calls.

The libsets in the gled repository.

GledCore is the implementation of the Gled system:

• the environment: libset and class catalogs, dynamic loading of libsets (Gled, GledNS, GledViewNS)
• the server, Saturn, and the executables gled and saturn
• the base classes ZGlass, ZList, ZHashList, ZNode and ZNodeLink
• the node hierarchy (SaturnInfo, EyeInfo) and the management of object spaces (ZKing, ZQueen, ZSunQueen)
• authentication and access control: identities (ZIdentity, ZGroupIdentity), method-call emitters (ZMirEmittingEntity) and filters (ZMirFilter, ZFilterAggregator, ZIdentityFilter, ZIdentityListFilter, ZMEESelfFilter, ZMethodTagPreFilter)
• threads of objects (Operator, Eventor)
• 3D scenes (Scene, Camera, Lamp, GlobalLamps, LampLink), the simplest shapes (Sphere, Box, Text, ScreenText) and GL state modifiers (ZRnrModBase, ZGlBlending, ZGlLightModel, ZGlMaterial)
• the GUI, the OpenGL rendering and the viewer (PupilInfo, ScreenDumper)

LibID = 2;
Libset_Name = "Geom1";
Libset_Deps = [ "GledCore" ];
External_Deps = [ DevIL ];

Geometric shapes, images and animation:

• images for textures, ZImage, loaded with DevIL
• GLSL programs and shaders, ZGlProgram and ZGlShader
• shapes: Rect (a grid), Board (a textured rectangle), SMorph (a textured sphere) and RectTerrain (a terrain on a rectangular grid, for any z = f(x,y))
• animation operators: Mover and Sleeper
• weaver symbols, WSSeed and WSPoint (axially symmetric tubes along a spline)
• colour gradients, RGBAPalette, with import of the POV-Ray gradients that gimp exports

LibID = 3;
Libset_Name = "Numerica";
Libset_Deps = [ "GledCore" ];
External_Deps = [ GSL ];

Numerical algorithms, and computations spread over a cluster:

• ODECrawler, a wrapper over the GSL integrator of ordinary differential equations; Moonraker uses it to shoot a shell from the Earth in the Earth-Moon system
• WarmAmoeba, simplex minimisation with simulated annealing; Spheror minimises the energy of N equal charges on a sphere, and MultiSpheror runs several of them on a Gled cluster

LibID = 4;
Libset_Name = "Audio1";
Libset_Deps = [ "GledCore" ];
External_Deps = [ OpenAL, freealut, vorbisfile ];

A wrapper over OpenAL: context, buffer, source and listener (AlContext, AlBuffer, AlSource, AlListener).

LibID = 5;
Libset_Name = "Net1";
Libset_Deps = [ "GledCore" ];
External_Deps = [ ];

UDP packet sources and listeners, their relay over TCP and their writing to ROOT trees (UdpPacketSource, UdpPacketListener, UdpPacketTcpServer, UdpPacketTcpClient, UdpPacketTreeWriter), and Ip4AddressLocator.

LibID = 16;
Libset_Name = "GledGTS";
Libset_Deps = [ "GledCore", "Numerica" ];
External_Deps = [ GTS ];

A wrapper over GTS, the GNU Triangulated Surface library: surfaces (GTSurf, GTSTorus), iso-surfaces from explicit equations (GTSIsoMaker) and retriangulation (GTSRetriangulator).

LibID = 33;
Libset_Name = "Var1";
Libset_Deps = [ "GledCore", "Geom1", "GledGTS", "Numerica", "Audio1" ];
External_Deps = [ ];

Terrains on triangle meshes, objects that crawl on them and fly over them, explosions, and a solar system: the technology demo of the Greed world. Includes the OPCODE collision library.

LibID = 64;
Libset_Name = "RootGeo";
Libset_Deps = [ "GledCore" ];
External_Deps = [ ROOT Geom, GLU ];

An interface to ROOT's geometry package (TGeo... classes): browsing and viewing of volume hierarchies (ZGeoNode), and checking for volume overlaps and viewing them (ZGeoOvlMgr, ZGeoOvl).

LibID = 128;
Libset_Name = "Tmp1";
Libset_Deps = [ "GledCore", "Geom1", "GledGTS" ];
External_Deps = [ ];

Work in progress: plants grown by L-systems (Plant, ProductionRule, ParametricSystem and the trees and herbs built on it), and drawing with a graphics tablet (TabletReader, TabletStroke).

The libsets for high-energy physics, in the gled-hep repository.

LibID = 65;
Libset_Name = "Alice";
Libset_Deps = [ "GledCore", "Geom1", "RootGeo" ];
External_Deps = [ ROOT Geom, EG, TreePlayer, Eve ];

Event display for the ALICE experiment: geometry, simulated and reconstructed tracks, V0s, kinks and hits.

LibID = 66;
Libset_Name = "AliEnViz";
Libset_Deps = [ "GledCore", "Geom1", "Var1" ];
External_Deps = [ ];

Visualisation of AliEn, the ALICE grid: sites, jobs and distributed analysis, fed from MonALISA.

LibID = 67;
Libset_Name = "XrdMon";
Libset_Deps = [ "GledCore", "Net1" ];
External_Deps = [ ];

A collector of the monitoring streams of XRootD servers: users, open files and their I/O, written to ROOT trees or reported when a file is closed.

Retired libsets, in the gled-attic repository.

LibID = 32;
Libset_Name = "TADemo";
Libset_Deps = [ "GledCore" ];
External_Deps = [ ];

Loads and renders the unit models of the game Total Annihilation. The game data is not included.
