ElgForward

An experimental forward renderer written with DirectX 11

Goals:

• Support Blinn-Phong and Cook-Torrance shading models
• Support normal mapping and bump mapping
• Support shadow maps
• Support for ambient occlusion (technique TBD)

Needed per-vertex data:

• Normal (for Blinn-Phong and Cook-Torrance, normal mapping, bump mapping)
• Texture coords (diffuse, specular, normal/bump, normal mapping)

Current agenda:

• Trackball camera
• FPS camera (?, http://in2gpu.com/2016/02/26/opengl-fps-camera/)
• Restructure the mesh, material, input layout architecture
  • Shader reflection
  • Move to using fcx to compile shaders
  • Move to using AssImp for loading to support wider range of mesh data
• Move to using handles for shaders, meshes, inputlayouts etc. and managers to enable caching
  • Add a drawable manager and drawable handle
• Scene loading
  • JSON Format
  • Loading of json
  • Loading of transforms for drawables
  • Loading of lights
  • Loading of textures
  • Change the camera update script to a general update script and expose buffers to it
• Shader reflection
  • Mapping of textures
  • Mapping of constant buffers and structured buffers
• General TODO:
  • Add mapping of custom shader input semantics to mesh channels
