[Ves] Size limit in the number of vertices

I am not seeing this extension..

GL_OES_element_index_uint

That would explain why you are having issues. We used to the code
where we would split the geometry (Pat: Did we remove that code?). If
not you can split the geometry and then load the data as usual.

Thanks

For me it is OK if generally speaking new / powerfull tablets can support > 65k vertices, but I would like to debug a little bit to understand the requirements. I will come back with some results but I will need some time as the Android world is quite new for me.

Of course, it's possible there is a bug and the runtime check is failing, even though your device supports the gl extension.  What device are you using?  Also, could you try the version of KiwiViewer that is in the Google Play store to see if that works any better?

Additionally in the Kiwiviewer example with the point cloud library (http://vimeo.com/42773717) it is stated that there are more than  200000 points (in IOS).
