The following are current news about the Gled project. Older news ...

Version 1.3.1 is available for download.

Release highlights:

• Added support for:
  • OSX
  • GLSL
  • stereo rendering
  • Ogg Vorbis audio
• Many additions and improvements in GledCore and Var1 needed for greed-prototype demo:
  • General infrastructure for attachment of controller objects (Spiritios) to Extendios. This includes key and overlay handling.
  • Basic inrastructure for sound effects -- explosions, weapon and engine sounds.
  • It is now possible to take first-person control over a Crawler, drive it around, control turret orientation and shoot other Extendios (buildings, crawlers and flyers). They explode when destroyed.
  • Added land-marks.
• Libset GTS renamed to GledGTS -- needed for library separation on OSX where filesystem is case-insensitive by default.

Version 1.3.0 is available for download.

The main motivation for this release is semi-public announcement of the Greed project. Most of the development over the last few years was devoted to prepartion of basic elements for Greed-world prototype demo.

Release highlights:

• New high-level build environment for building of external software and gled - gled-builder.
• Migration to SVN.
• Build system:
  • Added support for 64-bit compilation.
  • Added support for precompiled headers.
  • Proper install and blob_install targets.
  • Beautified output, control output level via GLED_ECHO_CMDS and GLED_QUIET environment variables.
• GledCore
  • Improved transparency of thread handling. Additional threads parameters are 'nice' value and name.
  • Complete rewrite of internal represesentation of container classes to support different internal tags for contained lenses (as lens pointers, as ints, or as strings). This allowed optimal implementation of new containers glasses ZVector, ZDeque, ZNameMap and ZStringMap.
    The main issue here was to allow all this to work correctly from the Eyes and within the GUI.
  • Separate the Eye and RenderDriver from GUI and OpenGL. Now they can be used in independent threads to: a) observe selected objects and to traverse selected object-graphs; b) send MIRs back into the Gled cluster.
  • Add time support to Eventor class - can feed on system time or use internal time-step.
  • Add overlay and overlay event-hadnling support. This allows for construction of GL-GUI elements, like buttons, pagers etc.
  • Support global scaling of color brightness, point-sizes and line-widths.
  • Introduce usage of frame-buffer objects (used for screen capture).
  • Use GLEW - The OpenGL Extension Wrangler Library.
• Geom1
  • New operator class TimeMaker that applies various transformations to Eventor>'s internal time and possibly delivers it to registered clients (that must implement the TimeMakerClient interface).
  • Improved implementation and functionality of weaver-symbol classes: connect arbitrary nodes, texture animation, some optimizations.
  • Many improvements to triangle-mesh class TringTvor needed for Greed-demo.
• Numerica
  • ODECrawler - add support for external storage of chunked integration results.
• New libset Var1 - it contains classes for Greed-world simulations of planetoids and solar-systems.
OPCODE library is used for collision detection.
