SimpleWindErosion

C++ implementation of a simple particle-based wind erosion system for terrain generation. This is an adaptation on related particle-based erosion systems, e.g. hydraulic erosion, designed to capture sediment transport, abrasion and cascading.

Rendered using my homebrew TinyEngine.

Link to a blog post about this.

Compiling

Use the makefile to compile the program.

make all

Dependencies

Erosion System:
- gcc
- glm
- libnoise

Renderer (TinyEngine):
- SDL2 (Core, Image, TTF, Mixer)
- OpenGL3
- GLEW
- Boost
- ImGUI (included already as header files)

Usage

./winderosion [SEED]

If no seed is specified, it will take a random one.
