Software rasterized raycast projected game engine with 3d editor and demo maps

---

This was a group project part of the 42 curriculum. It was built on our earlier Wolf3d-rasterizer project using its engine. My areas of focus in this project were:

Rendering

• Projection methon using rays and geometry
• Triangle processing
• Texture and normal mapping
• Triangle rasterization
• Shading and lighting

Animations

• An makeshift animation system that used multiple 3D objects in different poses as animation frames.
• Animation timers and triggers based on animation state

Physics

• Player collider and physics interaction

---

Features:

• Raycasted 3D (ray to triangle corners, screen intersection for rasterization)
• Parallel rendering with z-sorted triangles
• Depth shading + Simple Lights
• Normal mapping capability
• .obj file import and usage for world generation
  • homemade 3d models :)
• Full 3D map / scene editor
• Kd tree for raycast intersections & collision help
• AABB & ray collision
• AABB viewbox occulsion for objects & triangles
• Skybox
• A* path finding and node-based npc paths
• 3D animations
• 2D sprite effects
• Triggers
• Music & effects with SDL_mixer
• Fancy logs
• Debug lines
• Custom events
• ... lots more

Installation

Mac & Linux

Windows is not supported

1. Clone & Run :)

git clone https://github.com/hakolao/doom3d && cd doom3d
make && ./doom-nukem --default

# to create a standalone version run
./doom-nukem --convert-assets
# save first map in editor and then you can move
# the executable, levels, level_list.txt elsewhere and run standalone
./doom-nukem
