Sector Engine

A WIP project of mine to create a doom/build engine style 3D renderer.

Todo for initial demo:

• Basic rendering of colored walls
• Fix coordinate system jankiness
  • Make player and world behave in the same coordinate system.
• Rendering of colored floors/ceilings with simple geometry
• Rendering of colored floors/ceilings with holes
• Basic collision code
  • User collides with solid walls
  • User can pass through portals that have the same or lower floor height
  • User can step up to a certain height
• Rendering of textured walls
  • Textures loaded from disk
  • Textures default scale: 1px per map unit
  • Textures can be scaled
  • Textures can be rotated
  • Textures can be skewed
• Rendering of textured floors/ceilings
  • Textures loaded from disk
  • Textures default scale: 1px per map unit
  • Textures can be scaled
  • Textures can be rotated
  • Textures can be skewed
• Loading maps from Doom Wads
  • Convert to internal map format
  • They render correctly, but map functionality won't be there.
• Billboarded Sprites:
  • Single angle sprites face player 100% of the time
  • 8-angle sprites like doom monsters

Building

Building requires both CMake and Vcpkg.
