c++ - Evolution of QtOpengl -


as understand, there no modules in qt versions, there separate classes different functions, including graphical. opengl support realized in qt 1.2. however, qpainter, qimage existed in versions. so, correct these classes native (in other words, classes, primordial); opengl classes - non-native (it separste branch, after all)? i`d learn further evolution of qtopengl non-native , alternative way creating 2d graphics ih qt, influence of module on evolution of native methods (for creating 2d graphics).

so, correct these classes native?

no, not.

the reason "native" mean different things different people. matter of interpretation. see other question how confused got.

by now, think mean "non-opengl" 2/3d native. means software rasterization opposed going through display driver directly. so, still on qt level, without opengl classes in qt.

now, point can come qimage , qpainter. yes, qpainter initial generation software rasterization times gpus not common , cheap these days.

they doing rendering purely software techniques. is, more limited, worked without more expensive , less common hardwares around.

(those times of quake , other software products, fun times looking @ today's perspective ...)
