Slices scrolling performance in 2d canvas

[younes200]

Hi all, I Noticed slow 2d rendering performance when scrolling in slices, here is my example : http://my.slicedrop.com/?r9

I know that WebGL can be much faster than canvas 2D but can we improve the 2d render when scrolling by caching the buffered images ?

Thank you.

Hi Younes,

The links to your demo seems broken... Scrolling should be slow only the first time then once all the slices are cached it should be fast:

Here is how it works in XTK right now:

At load time: We cache only center slices in all directions. (i.e. only 3 slices so it loads much faster)

On scroll: If the requested slice doesn't exist, create it and cache it. If the requested slice is cached, render it.

Thanks
