The author covers the full architecture: embedding a self-hosted WebGL bundle into Webflow via attribute-driven mounting, using the Webflow MCP (driven by Claude) to build and maintain the entire site from code, processing real SRTM elevation data through Blender into Draco-compressed glTF assets, and writing a single procedural fragment shader with fwidth()-based anti-aliasing for the survey-contour terrain look. Key engineering challenges addressed include preventing first-paint flash with synchronous head CSS, avoiding React re-renders on scroll by using refs and GSAP ScrollTrigger, eliminating a ~1-second shader compile freeze with compileAsync, and achieving 60fps by freezing shadow maps, moving particle animation to the GPU vertex shader, and removing unnecessary MSAA on post-processing passes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I avoid a first-paint flash when injecting JavaScript into a Webflow site via a loader script? Put a synchronous cover directly in Webflow's head custom code, not in the loaded JS bundle, because loader-injected scripts run after the browser has already painted raw HTML. Use inline CSS setting a dark background and hiding body children with visibility:hidden, paired with a setTimeout failsafe (around 8 seconds) that removes the guard if the JS never loads, preventing a permanently blank page. _Developers wiring custom JS into no-code platforms can find similar rendering gotchas curated on daily.dev._ ### How can I stop falling snow particles from causing frame drops in a Three.js scene? Avoid re-uploading the entire particle position buffer from the CPU every frame, which causes GPU sync stalls, especially on fast GPUs. Instead, upload static positions once and compute the fall and sway motion inside the vertex shader using a uTime uniform with modulo wrapping, which produces an identical visual effect at near-zero per-frame cost and fixed one scene's frame rate from 37fps to a locked 60fps. _Anyone chasing GPU particle performance issues can track practical Three.js optimization write-ups via daily.dev._ ### How do I prevent a visible stall when swapping 3D scenes during page transitions in Three.js? Gate the transition reveal on GPU-ready state rather than parsed state by using gl.compileAsync to compile the new mesh's shader and upload its GLB off the main thread, only firing the scene-ready event once compilation finishes (with a 1200ms fallback timeout). This moved shader compilation off the visible reveal and eliminated a roughly one-second freeze on first scene reveal. _Developers debugging WebGL transition freezes can follow rendering performance techniques like this on daily.dev._ ## Similar posts on daily.dev - [Building Seamless 3D Transitions with Webflow, GSAP, and Three.js](https://daily.dev/posts/building-seamless-3d-transitions-with-webflow-gsap-and-three-js-vkf3mp1qr) · Codrops · 3 upvotes · 0 comments - [From Flat to Spatial: Creating a 3D Product Grid with React Three Fiber](https://daily.dev/posts/from-flat-to-spatial-creating-a-3d-product-grid-with-react-three-fiber-sstsygdip) · Codrops · 1 upvotes · 0 comments - [THREE.js-PathTracing-Renderer](https://daily.dev/posts/three-js-pathtracing-renderer-f7kf7vkhm) · Hacker News · 2 upvotes · 0 comments - [Digital Craft, Wild Soul: Building San Rita’s Topographic Web Experience](https://daily.dev/posts/digital-craft-wild-soul-building-san-rita-s-topographic-web-experience-0s7oamvwc) · Codrops · 11 upvotes · 0 comments --- Tags: [#nocode](https://daily.dev/tags/nocode), [#webgl](https://daily.dev/tags/webgl), [#threejs](https://daily.dev/tags/threejs), [#react-three-fiber](https://daily.dev/tags/react-three-fiber) [View this post on daily.dev](https://daily.dev/posts/building-ridgeline-engineering-a-real-time-3d-experience-in-webflow-p6ebijkqs) ```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":"Building Ridgeline: Engineering a Real-Time 3D Experience in Webflow","url":"https://daily.dev/posts/building-ridgeline-engineering-a-real-time-3d-experience-in-webflow-p6ebijkqs","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/building-ridgeline-engineering-a-real-time-3d-experience-in-webflow-p6ebijkqs"},"datePublished":"2026-07-22T13:56:59.845Z","dateModified":"2026-09-14T08:41:51.708Z","description":"A detailed engineering case study of Ridgeline, a cinematic 3D hiking site built in Webflow using Three.js and React Three Fiber.
