Coding Challenge 145: 2D Raycasting

Daniel Shiffman implements a basic 2D raycasting engine with line segment surfaces and vector rays using p5.js.

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. thecodingtrain.com/challenges/145-ray-casting-2d 🕹️ p5.js Web Editor Sketch: editor.p5js.org/codingtrain/sketches/Nqsq3DFv- 🎥 Next video: youtube.com/watch?v=vYgIKn7iDH8&list=PLRqwX-V7Uu6ZiZxtDDRCi6… 🎥 All videos: youtube.com/playlist?list=PLRqwX-V7Uu6ZiZxtDDRCi6uhfTH4FilpH References: 🌞 SIGHT & LIGHT by Nicky Case: ncase.me/sight-and-light/ 🌞 2d Visibility from Red Blob Games: redblobgames.com/articles/visibility/ 💾 p5.collide2D: github.com/bmoren/p5.collide2D 🗄 Line-line Intersection: en.wikipedia.org/wiki/Line%E2%80%93line_intersection Videos: 🎥 Coding Adventure: Ray Marching: youtu.be/Cp5WWtMoeKg 🎥 Matrix Math: youtube.com/watch?v=uSzGdfdOoG8 🎥 Coding Challenge: Rendering Ray Casting: youtube.com/watch?v=vYgIKn7iDH8 🔴 Coding Train Live 177: youtu.be/-6iIc6-Y-kk?t=1548s Timestamps: 0:00:00 Introduction 0:03:34 Coding Starts 0:05:54 Creating a Ray Class 0:09:16 Casting Rays And Finding Intersections 0:19:56 Casting Multiple Rays 0:24:41 Adding Collision Detection For Every Ray 0:26:47 Multiple Boundaries 0:31:23 Moving With Perlin Noise 0:32:41 Suggestions For Improvements Editing by Mathieu Blanchette Animations by Jason Heglund Music from Epidemic Sound 🚂 Website: thecodingtrain.com/ 👾 Share Your Creation! thecodingtrain.com/guides/passenger-showcase-guide 🚩 Suggest Topics: github.com/CodingTrain/Suggestion-Box 💡 GitHub: github.com/CodingTrain 💬 Discord: discord.gg/hPuGy2g 💖 Membership: youtube.com/thecodingtrain/join 🛒 Store: standard.tv/codingtrain 📚 Books: amazon.com/shop/thecodingtrain 🖋️ Twitter: twitter.com/thecodingtrain 📸 Instagram: instagram.com/the.coding.train/ 🎥 Coding Challenges: youtube.com/playlist?list=PLRqwX-V7Uu6ZiZxtDDRCi6uhfTH4FilpH 🎥 Intro to Programming: youtube.com/playlist?list=PLRqwX-V7Uu6Zy51Q-x9tMWIv9cueOFTFA 🔗 p5.js: p5js.org 🔗 p5.js Web Editor: editor.p5js.org/ 🔗 Processing: processing.org 📄 Code of Conduct: github.com/CodingTrain/Code-of-Conduct This description was auto-generated.
