Raycasting Engine

A pseudo-3D renderer in the Wolfenstein 3D tradition, ported faithfully from my Python engine. It marches 150 rays across the field of view, finds where each one hits a wall, and draws a vertical strip scaled by that distance. The left pane shows the real 2D map with the rays fanning out; the right pane is the 3D view they produce.

• Ray marching. Each ray steps forward through the grid until it strikes a wall.
• Map + 3D, side by side. Watch the 2D rays on the left build the 3D scene on the right.
• Move & turn. W/S to move, A/D (or arrows) to turn, or click-drag to look around.
