[VEX for Algorithmic Design] E23 _ SDF Basics

This is a new series I've started explaining the basics of VEX for algorithmic design / procedural modeling which I'm using on daily basis. In this 23rd episode, I'm explaining the basics of SDF to show how you can deal with it together with VEX coding with several examples. I've also started a Patreon, it would be great if I could get your support to continue creating tutorial contents. 00:00:00 Intro / What is SDF? 00:06:08 Check SDF Values with Points 00:23:38 Check SDF Gradient with Points 00:27:23 Visualize SDF Value with Fog Volume 00:37:19 Basic SDF Modification with VEX 00:43:48 Animated SDF Modification 00:47:11 SDF Modification with Gradient 01:03:21 Basic Collision with SDF 01:11:46 Animated Collision with SDF 01:21:16 Basic Vector Animation with SDF Gradient 01:36:50 Extended Vector Field from SDF 01:48:12 Next Topic - Basic Forces (Basic Physics) [Project Data Downloads] https://github.com/jhorikawa/VEXForAlgorithmicDesign [Patreon page] https://www.patreon.com/junichirohorikawa [Episodes] Episode 1 - Attribute Basics: https://youtu.be/V5i6KM_-8X0 Episode 2 - Group Basics: https://youtu.be/O18pzht4uvk Episode 3 - Parameter Basics: https://youtu.be/YKpqGx3TTps Episode 4 - Variables and Operations: https://youtu.be/vLPhHCZA5kw Episode 5 - Array: https://youtu.be/hboSqXvx0tg Episode 6 - Strings: https://youtu.be/3sDxeW_UfdA Episode 7 - Loop: https://youtu.be/EMKNE-RWwfY Episode 8 - Conditional: https://youtu.be/NoLFCfYlWj4 Episode 9 - Function: https://youtu.be/sl8QgnhWmyY Episode 10 - Volume Basics: https://youtu.be/chnB7_2Kkjs Episode 11 - Dictionary Basics: https://youtu.be/6fa6TT0uZHA Episode 12 - Vector Basics: https://youtu.be/7UB2hPax7Pk Episode 13 - Trigonometry Basics: https://youtu.be/gLOd_FFL58Y Episode 14 - Quaternion Basics: https://youtu.be/MYRtwY-DQV8 Episode 15 - Matrix Basics 1: https://youtu.be/ScYtNmnyF9A Episode 16 - Geometry Functions: https://youtu.be/-tTzZZuoRco Episode 17 - Intrinsic Attribute: https://youtu.be/MDFQkoV43ao Episode 18 - Randomness Basics: https://youtu.be/wOzqFwvunrM Episode 19 - Noise Basics: https://youtu.be/Q2OUvq4BcFk Episode 20 - Solver Basics: https://youtu.be/8CrVp5CyR5s Episode 21 - Half-Edge Basics: https://youtu.be/FpfA1CkH18E Episode 22 - Remapping Basics: https://youtu.be/wKDIa6UwQTk Episode 23 - SDF Basics: https://youtu.be/tbsmQBqf-9s Episode 24 - Force Basics: https://youtu.be/EOk-ln5Ir1s Episode 25 - Force Extended: https://youtu.be/Xdd5uWw9YvI Episode 26 - Recursion Basics: https://youtu.be/2ONYhyvGwJ0 [Houdini Related Playlists] VEX for Algorithmic Design: https://www.youtube.com/playlist?list=PLzRzqTjuGIDhiXsP0hN3qBxAZ6lkVfGDI Houdini Tutorial: https://www.youtube.com/playlist?list=PLzRzqTjuGIDgtI8wIsWVkU2-AVyDH91QM Houdini Algorithmic Live: https://www.youtube.com/playlist?list=PLzRzqTjuGIDizRMLtogMjkG8XpuPcb6ZM Houdini Snippets: https://www.youtube.com/playlist?list=PLzRzqTjuGIDhRtNf_CItwK3MYZQwdi7fB Houdini Tips: https://www.youtube.com/playlist?list=PLzRzqTjuGIDgdc2UP8gYerbrmBS7RQ2ce [Portal Page] Facebook Page: https://www.facebook.com/ParametricProceduralHoudini/ [Books] Algorithmic Design Workbook with Houdini: https://gum.co/GOZFw Tiling Pattern with Houdini: https://gumroad.com/l/OVDgY Algorithmic Design with Houdini: http://www.bnn.co.jp/books/9788/ Books on BOOTH: https://orangejellies.booth.pm/ [Contact] Twitter: https://twitter.com/jhorikawa_err
