This is a library to simulate plate tectonics. It is written in C++ and it has Python bindings (as part of this project), as well as Haskell bindings (hplatec)
The library offers an API to generate heightmaps and some other data about the world resulting from the simulation. The example permits also to generate maps like this one:
You can see a video of simulation based on an old version of this library: http://www.youtube.com/watch?v=bi4b45tMEPE#t=0
We use CMake. Install it and then run the folowing commands
cmake . -G "Unix Makefiles"
make
cmake .
make
This should produce a library (libPlateTectonics.a).
cmake .
cmake --build .
If you want to build also the examples run:
# instead of cmake .
cmake . -DWITH_EXAMPLES=ON
Note that this command will build the library in the same directory where the source files are hosted. Some prefer to build out of tree the library (i.e., in a separate dir). For example in this scenario:
-- plate-tectonics
\- build-directory
You can enter build-directory and type:
cmake ../plate-tectonics
make
To compile on other platforms please run:
cmake --help
To run also the examples you need to install the library libpng.
From the root directory run:
cmake -DWITH_EXAMPLE=TRUE -G "Unix Makefiles"
make
cd examples
./simulation_rect
To run tests you need to install DevIL
We use googletest (which is included in the project). After building the library:
cd test
make
./PlateTectonicsTest
Currently the test coverage is still poor (but improving!_, tests are present only for new code and tiny portion of the old code that were refactored.
Supported versions:
- Python 2.6 (currently not supported on AppVeyor)
- Python 2.7
- Python 3.2 (currently not supported on AppVeyor)
- Python 3.3
- Python 3.4
python setup.py build
The library is quite simple:
p = platec.create(seed=3)
while platec.is_finished(p)==0:
platec.step(p)
hm = platec.get_heightmap(p)
platec.destroy(p)
Or if you want more control:
p = platec.create(seed=3, width=1000, height=800,
sea_level=0.65,erosion_period=60,
folding_ratio=0.02,aggr_overlap_abs=1000000,
aggr_overlap_rel=0.33,cycle_count=2,num_plates=10)
- Improve the quality of the code and add some tests
- Support Google protocol buffer
