Features

Language       

• C++11, does not use any STL library and standard library.
• Headers only library
• Most functions are templates, which means you compile only what is used
• Compile-time polymorphism (no runtime virtual methods)
• Support for 32 bits and 64 bits
• Self contained and modular.

Geometry       

• Tesselation in any precision, fixed point precision, float or double.
• BiQuadratic/BiCubic Bezier Patch triangle Tessellation
• Quadratic/Cubic Bezier curve divider
• Elliptic Arc Divider
• Ear Clipping Tessellation for Simple (convex or concave) polygons
• X/Y Montone Tessellation for Monotone polygons
• Fan Triangulation for Convex polygons
• Stroke Tessellation with dashes (also supported with Path object)
• Fill Tessellation for any type of multi polygons using even-odd and non-zero rule
• Path object to easily define vector graphics and tessellate them using fill or stroke

Extra       

• Packed with fixed precision numbers Q class
• Computes boundary information for quick AA.
• Packed with triangles iterator for regular, fan and strip batch triangles
• Packed with many working examples

Installing micro{tess}

micro-tess is a headers only library, which gives the following install possibilities:

1. Using cmake to invoke the install target, that will copy everything in your system via

$ mkdir cmake-build-release
$ cd cmake-build-release
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ cmake --install .

2. Copying the include/micro-tess to anywhere you want.

Consuming micro{tess}

Following options are available:

1. copy the project to a sub folder of your project. inside your CMakeLists.txt add

add_subdirectory(/path/to/micro-tess)
target_link_libraries(your_app micro-tess)

2. If you installed micro{tess} with option 1 (see above) at your system, you can instead

find_package(micro-tess CONFIG REQUIRED)
target_link_libraries(your_app micro-tess::micro-tess)

3. If you have not installed, you can add in your app's CMakeLists.txt

target_include_directories(app path/to/micro-tess/folder/include/)

4. If you manually copied the include/micro-tess to the default system include path,
   you can use cmake/Findmicro-tess.cmake to automatically create the cmake targets

list(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/path/to/Findmicro-tess/folder)
find_package(micro-tess REQUIRED)
target_link_libraries(your_app micro-tess::micro-tess)

5. Just copy the include/micro-tess into a sub folder of your project and include the header
   files you need with relative path in your source files.

Running Examples

First make sure you have

• SDL2 installed at your system.
• microgl installed at your system.
• cmake installed at your system.

There are two ways:

1. Use your favourite IDE to load the root CMakeLists.txt file, and then it
   will pick up all of the targets, including the examples
2. Using the command line:

$ mkdir cmake-build-release
$ cd cmake-build-release
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ cmake --build . --target <example_name>
$ ../examples/bin/example_name
