Design Model Language IDE

DML is an IDE for modeling, simulation, and optimizing physical structures. DML stands for Design Model Language, which is the underlying format read by the IDE software. DML is an xml-like schema that allows users to define designs and simulations.

The DML-IDE utilizes Titan as its underlying physics engine. Titan provides a GPU-parallelized simulation library for near-real-time interaction.

Requirements

• A C++11 compiler
• CMake
• At least one CUDA-compataible GPU. See here for a list.

Build

DML-IDE has the following dependencies. Download and setup them up individually from the links below OR use a package manager (for everything but Qt and Lib3MF); vcpkg is highly recommended.

• Qt
• CUDA
• GLEW
• GLFW
• glm
• args
• pugixml
• Eigen
• Spectra
• Lib3MF

For installing Lib3MF first clone the repository from Lib3MF. Download along with submodule and move into the repository.

$ git clone --recurse-submodules https://github.com/3MFConsortium/lib3mf
$ cd lib3mf

Call GenerateMake.sh (Linux, Mac) or define other targets by specifying custom CMake generators (default is best unless you know what you're doing). A new folder “build” is created and contains projects for the IDE/build target you selected. For Linux/Mac:

• navigate to the “build”-folder
• Call “make” to build the projects
• Run/debug a project and install the library in the default location

$ cmake .. -DCMAKE_INSTALL_PREFIX=$INSTALL_PREFIX
$ make
$ make tests
$ make install

Lib3MF should now be ready to go.

Download DML-IDE from the GitHub source along with its submodules. Once downloaded, move into the repository:

$ git clone --recurse-submodules https://github.com/swyetzner/dml-ide
$ cd dml-ide

We are now going to create a build directory and use CMake to build into it:

$ mkdir build
$ cmake ..

Note: You may need to append some flags onto the cmake command if it fails:

• Point CMake to your local copy of Qt with -DCMAKE_PREFIX_PATH={path to Qt}/Qt/5.12.1/{architecture}/lib/cmake where architecture would be gcc_64 on Linux, clang_64 on MacOS, etc.
• If you are using vcpkg you need to add the flag -DCMAKE_TOOLCHAIN_FILE={path to vcpkg}/vcpkg/scripts/buildsystems/vcpkg.cmake.

We should now be able to make and run DMLIDE:

$ cd ..
$ make
$ ./DMLIDE
