General software features

The MLV library is a simplified multimedia library. This library has been designed for beginner students in C, and it allows to add graphical and audio effects on the student program. The library is useful to:

  • draw figures, display text and dialog boxes,
  • display images,
  • play sounds and musics,
  • catch mouse and keyboard events,
  • get informations from dialog boxes.

These tools are simplified interfaces of the SDL librairy. If you are not a C beginner, better use the SDL librairy (SDL, SDL_gfx, SDL_sound, SDL_ttf).

The MLV library is portable, and can be compiled and executed on Linux, Macintosh and Windows.

Context in which the software is used

Theaching first university level in informatics, C iniciation.

Proland : an OpenGL/C++ library for the real-time rendering and editing of large scale natural scenes

This software was developed (or is under development) within the higher education and research community. Its stability can vary (see fields below) and its working state is not guaranteed.
  • Web site
  • System:
  • Current version: 2.1 - 20/07/2009
  • License(s): source code not public
  • Status: under development
  • Support: maintained, ongoing development
  • Designer(s): Eric Bruneton, Antoine Begault

General software features
  • real-time rendering of multi-resolution terrains (up to a whole planet)
  • real-time rendering and editing of vector data (representing for instance roads or rivers)
  • real-time rendering of planetary atmospheres and clouds (from all viewpoints from ground to space)
  • rendering of forests using billboards

Proland can render very large natural scenes, at all scales and from all viewpoints from ground to space. The landscape data is loaded on the fly based on the current viewpoint (only the data needed for the current viewpoint is stored in memory, at the appropriate resolution). The landscape data can be procedurally modified on the fly. For instance the shape and texture of a terrain can be modified based on vector data representing roads or rivers.

Proland is based on a task graph and a cache manager taking advantage of multi-processors, supporting data prefetching to reduce disk latencies, and automatically managing the dependencis betwen tasks (procedural data are automatically recomputed when their input data change).

Context in which the software is used

Proland is used internally for research work about natural scenes (rendering, modelisation, animation). It is also used externally in two industrial projects (planetarium and flight simulator).
