No-plugin rendering

4d.io uses WebGL 2.0 to deliver high-fidelity 3D+time visualization directly within any modern browser. This removes dependency on external plugins or native installations, simplifying deployment and ensuring consistent access across operating systems and devices. The runtime leverages modern GPU features efficiently—such as instanced rendering and compute shaders—enabling complex scene graphs with thousands of moving entities to render at 60 frames per second on mid-tier hardware.

WebAssembly extends capabilities beyond what JavaScript alone can achieve, providing near-native speed for geometry processing, physics simulations, and time-series interpolation. This allows users to run custom animation logic, procedural generation, and large-scale spatial queries inside the browser without relying on remote servers. Scalability is built-in: the same core engine adapts rendering quality automatically based on device performance and connection characteristics.

From tablet-based design reviews to large-screen or head-mounted immersive setups, the rendering pipeline maintains spatial coherence and temporal synchronization. Users working on urban change models or infrastructure timelines can share live sessions with others using different hardware without visual or functional degradation. The architecture supports progressive enhancement, so core functionality remains usable even under constrained network or compute conditions.
