Good morning.I’m Gwangyoon from Company 100.Today we’re going to see CanvasGL,A true GPU-Accelerated WebKit for Android.
We have fully accelerated the GPU in two areas: HTML5 2D Canvas and CSS3 animation. We mean FULLY.
Then if we have a thousand draw calls, the CPU cost will be a Thousand times higher. And this makes the GPU acceleration to be CPU bounded.This makes the GPU Accelerated 2D Canvas extremely slow.

This structure is the problem.How do we solve this?
