My own OpenGL game engine. I write the code in Java, using the LWJGL.

• PBR rendering
• terrain system
• UI
• level editor
• loading/saving

• GameObject based scene graph
• Component system, including dependency handling
• chance to store Components based on type
• orthographic and perspective camera with frustum culling (sphere and AABB)
• load various model and texture formats
• Bezier and Catmull-Rom splines
• MSAA, vSync, various texture filterings, wireframe mode
• customizable rendering pipeline and material system
• Blinn-Phong shading
  • directional, point and spotlights
  • normal mapping and POM
• shadow mapping with PCF (only for directional light)
• post processing effects like tone mapping or FXAA
• data caching mechanisms
• keyboard, mouse and joystick input handling
• logging and statistics

Schedule for new features: https://trello.com/b/Kt2S5Tz4/engine

• wrong shadows on surfaces using POM
• POM distortion using orthographic camera
• works only on Windows

The source code contains the Netbeans project files, so Netbeans can directly open it as a standard Java project. The following LWJGL components need to build the program:

• LWJGL core 3.1.2
• JOML 1.9.4
• Assimp bindings
• GLFW bindings
• OpenGL bindings
• stb bindings
