Building off of the previous coding challenge (2D Ray Casting) I attempt to make my own version the original Wolfenstein 3D Raycasting engine and visualize the "field of view" of the moving particle.

Featured Challenge:
#188 — Voice Chatbot
In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

ray casting
In this video, I implement a basic ray casting engine with line segment "surfaces" and vector "rays." The result simulates a light source casting shadows in a 2D canvas.
