The slow rendering of Threejs is causing the browser to become unresponsive

Utilizing ThreeJS, I successfully created a captivating 3D scene with ten thousand particles arranged in a specific layout. Rendering these particles in the 3D world was seamless thanks to ThreeJS. However, I encountered an issue where the browser would display a blank screen for approximately 30 seconds during the rendering process. This delay is quite inconvenient for users.

Could someone kindly suggest how I can address this prolonged rendering time or enhance the efficiency of the rendering process? Any assistance on this matter would be greatly valued!

Answer №1

Without actually seeing the code, it's hard to determine the exact cause of the delay. If the issue lies with JavaScript, you could try measuring it using benchmarks like console.time. However, if the problem is with your GPU, reducing the number of particles may help alleviate the issue.

Answer №2

Adding all particles at once using a for loop may result in the rendering loop being blocked. Consider adding particles in smaller batches, such as a thousand at a time, until you have reached your desired quantity.
