This one's for when you need actual 3D on the web without the usual performance nightmare. Covers the full stack from React Three Fiber and vanilla Three.js to Spline for quick prototypes, plus the unglamorous but critical parts like model compression with gltf-transform and mobile fallbacks. The scroll-driven 3D patterns are especially practical since that's where most clients want to use it anyway. Honest about when 3D is overkill, which matters because too many sites add floating geometry that just murders mobile battery life. If you're building product configurators, portfolio pieces with depth, or anything where 3D actually serves the experience rather than just looking cool, this gives you the decision trees and optimization workflow you need.
