Rendering 3D Worlds in C#
summary
A working raycaster written in C# converts a 2D string-array map (hashes = walls) into a 3D view by casting 1024 rays (one per horizontal pixel) and measuring distance to fill vertical columns; it runs from a .NET Core 3.1 console, uses ImageSharp to write bitmaps and a WinForms PictureBox to show a 60fps interactive demo, totals about 200 lines of code, supports simple lighting and floor/ceiling cheats, and successfully reproduces Wolfenstein-style rendering.
