function updateViewerFrame() const frame = document.getElementById('liveViewerFrame'); const timestamp = new Date().getTime(); // Append the updated timestamp to force a true network refresh frame.src = `/live/viewerframe?mode=refresh&updated=$timestamp`; setInterval(updateViewerFrame, 40); // Refreshes approximately 25 times per second Use code with caution. 3. Inspect Network Protocols and CORS Settings
Do not allow the viewerframe to refresh on every single micro-change. Implement a debounce mechanism (e.g., waiting 300ms after the user stops typing or moving an object) before executing the refresh cycle. Use Conditional Rendering (Diffing)
To make the most of these updates, consider the following best practices: viewerframe mode refresh updated
However, the keyword has taken on a second life as a piece of . It serves as:
[Data Change] ➔ [Refresh Triggered] ➔ [Cache Cleared] ➔ [State Updated] ➔ [Frame Rendered] 1. The Trigger (Data Mutation) function updateViewerFrame() const frame = document
The newly updated refresh protocols prioritize delta-updates. Instead of destroying and rebuilding the frame canvas, the engine targets only the modified coordinates or properties. This shift lowers CPU overhead and prevents the classic "white flash" associated with older iframe refreshes. Step-by-Step Optimization Guide
Understanding is critical for building responsive, efficient viewing applications. The optimal refresh strategy depends on the active mode, user expectations, and system constraints. Separating visual refresh from data update cycles, using partial rendering where possible, and matching refresh rate to the mode’s needs will yield the best performance and user experience. Implement a debounce mechanism (e
Legacy implementations of viewport frame refreshing relied heavily on heavy polling mechanisms or rigid frame-rate caps. Recent software updates across web graphics engines (WebGL/WebGPU), CAD software packages, and real-time dashboard frameworks have fundamentally overhauled this mode. The latest updates introduce three major improvements: 1. Micro-Task Batching
