Rendering depth map

[gkntonfo]

Did you try to render in using OGL? Qt doesn't provide some special rendering methods, it just provides convenient wrappers on top of standard OGL/ES.

Thank you for your reply.
I had looking for some code in OpenGL but it seems so complicated to me(I'm a newbie) and unfortunately I have no time to learn OpenGL. I hoped that Qt provided some rendering methods through Qt3D. Could you please show me how to render depth map using OPENGL? do you have some example code? thank you again.
