[Ves] VES-kiwi for Win8

[Carlos]

Hi David,

It sounds really well.

Could you please tell us where we can find more information about this?. I
have made a quick google search with vkt + ARB_ES2_compatibility but I have
not find any relevant link, expect some headers. I have also checked the
flags in Cmake for VTK  6.1 but I can't see this flag.


regards,

Hi Jamie,

> Aplogies for my ignorance but does this mean that the new VTK rendering
code, which iirc targets open gl 2.1+, can be run on desktop or mobile
applications?

After a fashion. VTK's new rendering layer will target OpenGL 2.1 as the
minimum required, but should also work with OpenGL4.1, which exposes an
extension named ARB_ES2_compatibility. By enabling that extension and
avoiding OpenGL calls that are not part of OpenGL/ES2, VTK applications
should be able to target both desktop and mobile platforms.

I expect that some rendering techniques will use OpenGL calls not part of
GL/ES2 but the plan is for the core VTK rendering classes to stick with a
pretty minimal subset of calls. Also, some mobile devices may  come with
full OpenGL (not GL/ES) support, in which case more rendering techniques
could be supported (assuming the drivers aren't buggy... nervous laughter).
