2002_DOS_3D_raytracing_game

Ray tracing based game engine (similar to wolfenstein game engine), 32-bit MS-DOS

The game was written for the MS-DOS platform in TMT Pascal 32-bit. The graphics mode is SVGA with a resolution of 800x600 and 256 colors. The engine is based on ray tracing on the 2D map and then rendering the texture column like in Wolfenstein and Doom games. The inner loop is optimized in assembler for the 80486 processor, on which the engine at 800x600 resolution works with sufficient performance. Graphical assets are obtained from RAM dumps of the game Heretic.
