Each entry links to slides, source code, papers, or YouTube recordings. ## Full article daily.dev links to this article rather than hosting it.

A dedicated publications archive collects Erin Catto's GDC presentations from 2005 through 2019, including Sequential Impulses (2006), Iterative Dynamics (2005), Soft Constraints (2011), Continuous Collision (2013), Understanding Constraints (2014), Numerical Methods (2015), and Dynamic Bounding Volume Hierarchies (2019), each with downloadable slides and some with source code or paired YouTube recordings. _daily.dev surfaces resources like these for developers digging into physics engine internals._ ### What technique does Box2D use to compute distance between convex shapes? Box2D uses the GJK (Gilbert-Johnson-Keerthi) algorithm for computing distance between convex shapes, as detailed in Erin Catto's GDC 2010 talk 'Computing Distance using GJK,' which includes both slides and accompanying source code for implementing the algorithm. _Developers comparing collision detection approaches can track deep dives like this on daily.dev._ ## Similar posts on daily.dev - [Announcing Box3D :: Box2D](https://daily.dev/posts/announcing-box3d-box2d-mu8ehdvki) · Lobsters · 0 upvotes · 0 comments - [Box3D Debuts As New Open-Source 3D Physics Engine](https://daily.dev/posts/box3d-debuts-as-new-open-source-3d-physics-engine-xsk1j9ymw) · Phoronix · 0 upvotes · 0 comments - [Lightweight Box3D Physics Plug-In For Unreal Engine 5](https://daily.dev/posts/lightweight-box3d-physics-plug-in-for-unreal-engine-5-xpojprmph) · 80 LEVEL · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/publications-box2d-gzuvtb3sk) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Publications :: Box2D","url":"https://daily.dev/posts/publications-box2d-gzuvtb3sk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/publications-box2d-gzuvtb3sk"},"datePublished":"2026-08-23T12:16:48.960Z","dateModified":"2026-08-23T12:17:21.365Z","description":"An archive page collecting Erin Catto's Box2D and Box3D benchmarks along with his GDC talks spanning 2005 through 2019, covering topics like dynamic bounding...","image":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","thumbnailUrl":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","isAccessibleForFree":true,"articleSection":"\n \n Box2D \n \n ","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"\n \n Box2D \n \n ","logo":"https://media.daily.dev/image/upload/s--fmoS1AL5--/f_auto,q_auto/v1787487406/logos/box2d?_a=BAMAMicg0","url":"https://daily.dev/sources/box2d"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/publications-box2d-gzuvtb3sk","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"\n \n Box2D \n \n ","item":"https://daily.dev/sources/box2d"},{"@type":"ListItem","position":3,"name":"Publications :: Box2D"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/publications-box2d-gzuvtb3sk#faq","mainEntity":[{"@type":"Question","name":"Where can I find Erin Catto's GDC talks on Box2D physics engine internals like constraint solving and collision detection?","acceptedAnswer":{"@type":"Answer","text":"A dedicated publications archive collects Erin Catto's GDC presentations from 2005 through 2019, including Sequential Impulses (2006), Iterative Dynamics (2005), Soft Constraints (2011), Continuous Collision (2013), Understanding Constraints (2014), Numerical Methods (2015), and Dynamic Bounding Volume Hierarchies (2019), each with downloadable slides and some with source code or paired YouTube recordings. daily.dev surfaces resources like these for developers digging into physics engine internals."}},{"@type":"Question","name":"What technique does Box2D use to compute distance between convex shapes?","acceptedAnswer":{"@type":"Answer","text":"Box2D uses the GJK (Gilbert-Johnson-Keerthi) algorithm for computing distance between convex shapes, as detailed in Erin Catto's GDC 2010 talk 'Computing Distance using GJK,' which includes both slides and accompanying source code for implementing the algorithm.
