A walkthrough of building a browser-based 3D text engine from scratch using only math and vanilla JavaScript — no WebGL, no external libraries. The engine represents letters as extruded 3D wireframes, applies rotation via sine/cosine, renders into an ASCII character framebuffer with a Z-buffer for depth testing, uses character gradients for shading, and implements near-plane clipping to prevent projection artifacts. The full render loop uses requestAnimationFrame and fits in a few hundred lines of code.

<p>Really impressive to see 3D rendering done with just math and vanilla JS. Using a Z-buffer and ASCII shading without WebGL is a great way to understand how rendering actually works under the hood.</p>
