For details take a look to the full manual.
lltool provides several methods and algorithms for heightmap manipulation and terrain triangulation. Steering of the process is done via a batch script with a small and dedicated scripting language. The terrain triangulation is done in two steps: in a first step vertices are placed, either based on vertex placing methods, or via (a combination) of density algorithms. In second step the vertices are triangulated and the resulting mesh can be further manipulated. lltool provides multi-level LODs, break lines and polygon stencils.
- Map creation and manipulation: importers/exporters and basic terrain moddeling
- Support for cells and quads (for game LODs)
- Multiple algorithms for random Monte-Carlo vertex placement, e.g. based on first and second order, height, peak finding, and general purpose equations
- Triangle manipulation: stencils and break lines
- Output formats for meshes: obj- and VRML-files
- Texture map handling (import, export, scaling)
- Formats for textures: bmp and dds
Go to the directory "externals". lltool needs (in addition to the included packages):
- MTParser by Mathieu Jacques, download the code and put it into externals/mtparser (Windows only!!!)
Windows:
- Open lltool.sln and build the project.
Linux:
- Run "make"
The command can be followed by several flags (see batch section in the full manual) in order to propagate variables to the execution script.
The section used by the execution script is defined by a section name in squared brackets (like the section in the script).
The last option might be the filename. If no filename is given, stdin is used, in this case, reading can be stopped with @end.
