Sadly, some graphic cards driver don't properly support all OpenGL commands. And the OpenGL 'picking' command we use is kind of old and more and more deprecated... Which means that this feature simply doesn't work with some graphic cards/drivers!

Today I implemented this function in windows,

the reason is:

mouse click is difficult to point to point in 3dviewer,

if I click to point, the above function can be realized.

Is there a way to increase the sensitivity of mouse clicks?
