3D-Engine-OpenGL-4

3D Game Engine (made with API OpenGL 4.1) for C++

Engine features:

• Blinn-Phong lighting
• Bloom/HDR effect
• Omnidirectional shadows
• Perspective/orthogonal camera
• Multisampling
• Particles generator
• Terrain generator based on 2D heightmap and tessellation
• Terrain LOD - level of detail
• Water with reflection and refraction
• Heightmap 2D/3D generator based on Perlin noise and random noise
• Heightmap to normalmap converter based on Sobel operator
• Input/output based on GLFW
• Model loader based on Assimp
• Skeletal animations
• Font rendering based on FreeType

Engine delivers simple shaders that support features of this engine.

Engine structure:

  / - base engine class, config, include 
  base/ - shader and program compilators, texture class
  buffer/ - buffers e.g framebuffers
  camera/ - classes of cameras 
  renderable/ - everything what you can render
  scene/ - scene class
  support/ - supporting files
  texture-generator/ - noise, heightmap, normalmap generators
  window/ - window class
  shaders/ - proposed shaders
