# func-renderer

This is OpenGl 3.3 based renderer for noise functions to experiment with terrain generation.

It uses expression templates to compose multiple height functions in compile time.



# build

* clone repo

* update submodules

* Use the CMakeLists.txt in the main folder to generate platform depend build files

* build with toolchain of your choice

tested: msvc2019, gcc 8.1.0

# usage

A variaty of useful functions can be found in functions1d.hpp, functions2d.hpp and modifiers.hpp.

Examples on how to combine and render them are located in scene.cpp.

To display a specific scene change the type in main.cpp.

If you want to display 1D functions make sure to #define MODE2D in config.hpp,

otherwise remove it.
