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.
