Use OffScreenCanvas and WebWorkers #19

Open johannbuscail opened 3 years ago

johannbuscail commented 3 years ago

Issue

Slowness

Solution

Instead of using just the main thread with a canvas that needs to render, It would be faster to use a WebWorker to create another thread and use an OffScreenCanvas to not render everything when it's not needed.
