DSO-Refractor

OpenGL terrain + static objects renderer for Battlefield 1942 (Demo — Tobruk/Tunisia).

Loads the original .rfa archives from the BF1942 Demo — heightmap terrain, 415 static objects (buildings, bunkers, walls, sandbags), all textured from the original DDS files.

Build & Run

# Requires: SDL2, GLEW, OpenGL 3.3+, X11
make bin
LD_LIBRARY_PATH=/home/lain/dsa ./dsr-bin

Data files (data/*.rfa, bf1942_data/) from the BF1942 Demo must be present.

Controls

Key	Action
WASD	Move camera (XZ plane)
Q / E	Move camera up / down
RMB (drag)	Mouse look
F2	Toggle wireframe
R	Cycle rotation mode
M	Toggle mirror
Esc	Quit

Features

• BF1942 .sm mesh loader (v9 format, Z-up → Y-up conversion)
• .rs shader parser (material→texture mapping)
• DDS texture loader (DXT1/3/5) from texture.rfa
• Terrain heightmap sampling (Heightmap.raw)
• Per-object .con positioning, rotation, scale (415 objects)
• Multi-material mesh merging (all geometry visible)
• 136 unique DDS textures loaded

Architecture

dsr/        — core library (mesh, render, terrain, rfa, etc.)
main.c      — game loop, object loading, camera
data/       — BF1942 Demo archives (standardMesh.rfa, texture.rfa, etc.)
bf1942_data/ — level configuration files
