hpn4/hengine

A small (unoptimized) game engine written in Java (with LWJGL)

HEngine

A simple and terribly inefficient game engine written in Java (using LWJGL) during my school years. It was a fun project to work on and I learned a lot from it. It's not really useful for anything, but I'm keeping it here for sentimental reasons.

Features

I implemented a lot of features in this engine, but most of them are not very efficient. I was still learning about 3D rendering at the time, so I didn't really care about performance. I was more interested in learning how to implement these features than making them efficient. Here are some of the features I implemented:

Lights:

• Directional lights
• Point lights
• Spot lights

Meshes:

• Support animated models
• Support most common file formats (all supported by Assimp)
• Basic support of transparency

VFX and advanced rendering techniques:

• Particle systems
• Fog
• Skybox
• SSAO
• Bloom
• Shadows
• Decals

Optimization:

• Frustum culling
• Mesh Instancing
• GBuffers (deferred rendering)

Technical details

I used LWJGL with the following libraries:

• Assimp for model loading
• STB for image loading
• JOML for math
• NanoVG for UI rendering
• OpenGL for rendering
• GLFW for window management
• OpenAL for audio

I also create a small lib on top of GLFW and NanoVG to create a swing like UI system.
