Serenity

OpenGL 3d terrain engine written in Kotlin and LWJGL.

Experiment results:

• Terrain generation and rendering (with dynamic LOD on the GPU)
• Ocean rendering (based on the Fast Fourier Transform on the GPU)
• Instanced model rendering (trees and grass)
• SkyDome rendering
• Post Processing effects (Light Scattering also known as God Rays)

Requirements

• Kotlin 1.9
• JDK 17
• Maven
• OpenGL 4.6 compatible video card

Project setup

• maven build - for building in IDE
• maven package - for packaging in executable binary

For now supports only windows-x64 natives

To build and compile for other platforms add lwjgl natives in maven build section
