hi. i want to create 3D aid programs. i am newbie in qt world. likely my chooses will be Qt 3D or Qt OpenGL. but in my few studies that i do on these subjects i can not choose correct choice. in Qt examples i saw any good examples. but i studied and saw opengl for qt 5 base implementation works has any different by Qt 4. i using Qt 5.8. i read Qt documentation but i think don't understand it. so i follow this series instead: link text thanks Trent. that is good but i stopped at part 1. because has error about opengl es and others .can you view erros here: link text . but Qt 3D is other choice. but my main problem is that Qt has multi way to 3d working. this multi ways confusing me for choose best way and easy and correct way. really i want to design programs that use 3d models. for example medicine programs that show body models. or body details models of course i need a property designer beside it(that is my other problem to choosing between Qt Widget or Qt Quick . because in my brain design i want to have a comprehensive IDE that have 3D viewer beside form elemetns such menus toolbars and property modifier to render 3d model and change it on time). or want to creating free 3d works in qt. really can i use Qt for these works? i remember that install and build pure opengl libraries such as (GLUT,FreeGLUT,GLFW,GLEW) in visual C++ in VS . then can create all objects easily. and i have not problem in multi ways of choosing. because i worked on pure opengl and i could read all opengl books and implement any opengl tutorials. but in Qt exist mutli ways and multi confuse classes. and this multi ways and errors is hard to learn opengl for me. since all c++ developers suggest Qt framework because it is best c++ framework .i like it too. but really it is hard to understand opengl works and 3d works on it for me. please help me... excuse me for my long topic. i wanted to describe my problem mean better. thanks for your attention

Most of the code you'll write won't be C++ but GLSL . There is no such thing as "Qt vs. pure libraries". With Qt Widgets you just create a window, get a pointer to the OpenGL functions and then use them. Doesn't get any "purer". There are only a few functions you need on the C++ side to get your OpenGL stuff running. So few, you can write them down on a single sheet of paper. All the rest has nothing to do with Qt or anything but is a different programming language (GLSL). To learn that you better borrow a few books from your local library.

but on my work pc not run.

Maybe your PC has a terribly outdated GPU or the driver has some problem.

do you tell me good tutorials ?

Actually I like Trent's tutorial for the Qt integration part. Anything else: get a book on GLSL.
