Context
A Wolfenstein-inspired renderer that converts a 2D map into a textured first-person scene using raycasting. The project includes map validation, player movement, collision detection, wall projection, textures, and a minimap.
My responsibility
Built and validated through the 1337 / 42 project curriculum, with direct responsibility for implementation, debugging, testing, and evaluation requirements.
System scheme
Engineering scheme
2D map to raycast frame
Every screen column traces a ray through the grid, resolves the nearest wall, and samples a texture at the projected height.
- 01
Map parser
Validate scene directives, textures, colors, and enclosed geometry.
- 02
Player camera
Track position, direction vector, and camera plane.
- 03
Ray generation
Create one world-space ray for each screen column.
- 04
DDA traversal
Advance through grid cells until a wall is intersected.
- 05
Wall projection
Correct distance, calculate slice height, and select texture data.
- 06
Frame buffer
Draw walls and minimap, then present the completed image.
Implementation breakdown
- 01
System design
Digital Differential Analysis (DDA) finds wall intersections for each screen column, then projection math determines texture sampling and rendered wall height.
Technical scope
Implementation details
- ✓Fully textured wall mapping spanning distinct geographic compass orientations.
- ✓Fluid first-person camera rotational controls mitigating visual tearing.
- ✓Dynamic minimap array generation parsing real-time object coordinates.
Engineering focus
- →Linear algebra remained an explicit concern across the implementation.
- →Collision detection remained an explicit concern across the implementation.
- →Texture sampling remained an explicit concern across the implementation.
- →Frame performance remained an explicit concern across the implementation.
