DunGen library - a generator for procedural 3D dungeons

[Squarefox]

Ho ho ho,

winter is coming and Santa Squarefox has a nice present for you: "DunGen" - a procedural Dungeongenerator library for Irrlicht.
DunGen is a generator for procedural 3D dungeons. Methods of procedural synthesis, such as L-system, Voxels and Hermite-Splines are used to generate these dungeons. These dungeons can be used in computer games and other applications. The generation of a complete dungeon usually takes less than a half minute (under 10 seconds on a modern Core i7 processor).

Features:

• generation of procedural voxel bases caves, which can be eroded, filtered, warped and smoothed so that they look more realistic
• generation of procedural corrdiors between cave parts and/or rooms
• computation of visibility information (can you look through a corridor - yes or no?)
• place detailobjects (e.g. torches or monsters) in the corridors
• use .irr scene files to provide roompatterns for your dungeon

The library package contains everything you'll need:

• the compiled library, including source code in C++ (provided as a Visual Studio 2010 project)
• a compiled tutorial, including source code in C++ (provided as a Visual Studio 2010 project)
• a doxygen documentation, compiled as HTML

Here are some screenshots:






The package is downloadable at http://dungen.squarefox.net . Version 1.0 is compiled for and compatible with Irrlicht 1.8.1 .

I hope you enjoy this library!

Kind regards,
Squarefox

Nice Screenshots :-)

Thank you !

Very good work, the roughness of the ground bothers me though. :)

[Squarefox]

Thanks . The roughness is achieved through a combination of voxel erosion and warping of vertex coordinates when transforming the original voxel cave into a mesh. The shown pictures use smooth warping. It's also possible to deactivate the smoothing via option, then the result is rougher. If you don't use erosion, but smooth warping, then you get smoother caves, as shown in picture 2.

Hi,

I just released version 1.1 of DunGen. The following changes were made:

• some refactorings (especially CCorridor) to make code more readable, no changes on functionality here
• added StartUp/ShutDown functionality, to make more RAM available to user
• added ClearRoomsAndCorridors function: no need for restart of DunGen, if an other dungeon shall be created
• added ReadDungeonFromFile function: dungeons can now be read from XML
• added second tutorial, which shows how to read dungeons from XML

Here is another screenshot:

Hi,

I now released version 1.2 of DunGen. The following changes were made:

• added SetMaterialCustom function, which allows you to use custom materials for the cave and corridors
• added third tutorial, which shows how to use custom materials
• added RandomCaves tool, which generates caves from random L-systems and allows you to save them for later usage

The package is downloadable at http://dungen.squarefox.net . Version 1.2 is compiled for and compatible with Irrlicht 1.8.1 .

Hi,

version 1.2.1 of DunGen is now released. The following changes were made:

• implemented a EnsureIntegrity() function in CVoxelCave to ensure a 3 voxel border, to catch some numerical problems that could lead to crashes when filtering the cave

The package is downloadable at http://dungen.squarefox.net . Version 1.2.1 is compiled for and compatible with Irrlicht 1.8.1 .

Hi,

I released version 1.2.2 of DunGen. The following changes were made:

• fixed an issue with StartUp(), where several StartUp() calls with no ShutDown() caused a memory leak
• fixed an issue where detailobjects settings where not overwritten correctly when reading a dungeon from xml

The package is downloadable at http://dungen.squarefox.net . Version 1.2.2 is compiled for and compatible with Irrlicht 1.8.1 .

Hi,

version 1.2.3 of DunGen is now released. The following changes were made:

• fixed an overlapping polygon in tutorial dungeon 1 by adding adding additional digging depth into the corridor descriptions of this dungeon

The package is downloadable at http://dungen.squarefox.net . Version 1.2.3 is compiled for and compatible with Irrlicht 1.8.1 .

Newest version (1.2.4) is downloadable here: https://github.com/thesquarefox/dungen .
The license was adapted to be fully zlib (as Irrlicht).
