[Bf-committers] problem when expanding BGL to deal with (GLchar **)

[Dalai Felinto]

>Your patch doesn't account for machines that do not support shaders.
Why would it? bgl currently supports DisplayList but computers that don't
support it will crash blender just as well.

I do agree that will be nice to allow bgl to query the supported features
in the graphic card. But it will be up to the (py) developer to implement
it correctly.

*My problem is that I need to create a pointer of pointers as it seems. I
hope it's doable.*

(and if you are wondering what computer nowadays do not support DL try to
remote desktop in a computer and you get a system that doesn't support even
VBOs)

I want a solution easy to use in add ons, thus the idea of extending bgl.

Thanks,
