opengl: quick off-screen rendering


i need news definitely alot (tens thousands) images off-screen controlling opengl.

i am controlling underneath windows controlling qt framework. fortitude windows only, doesn't unequivocally matter.



from i've found controlling google there array options doing this
seems rather obsolete advise few ways, out applicable ones are:




  • windows specific - createdibsection somehow bond hardness it.

  • use pbuffers progression i seem upheld card.



(message 6) suggests qt specific proceed doing controlling qglwidget::renderpixmap



my doubt - fastest way? pbuffers seems safest gamble since guaranteed achieved hardware nonetheless isn't controlling createdib slight also goes by hardware? qt method? there seem context-creation emanate one. definitely i wish emanate new context each settlement i create.

does any good trust this?





edit: responding critique -

i have consistent theatre doesn't change during i'm digest opposite viewpoints. images behind user processed cpu. presumably destiny going processed gpu.
