Making Graphics Like it's 1993: Building the Catlantean 3D Retro Engine
Original: Making Graphics Like it's 1993
A deep dive into building Catlantean 3D, a retro software rendering engine under 1993 hardware constraints.
This post kicks off a series on building Catlantean 3D, a retro engine replicating 1993 graphics technology. The author bypasses modern GPUs to implement pure CPU software rendering, fixed-point math, and 256-color palettes. It offers a fascinating look into early 3D algorithms like raycasting and affine texture mapping, serving as an educational resource for low-level graphics.
在現代 3D 繪圖技術中，我們習慣了 WebGPU、DirectX 12 和 Unreal Engine 5 等強大工具，GPU 幫我們處理了幾乎所有的光柵化、著色與深度測試。然而，在 1993 年（《毀滅戰士》Doom 誕生的年份），3D 繪圖是一場在極度受限的硬體上進行的極限運動。
