There is apparently no difference in OpenGL mode. I picked a point from inside but it's in fact the closest point of outside.

Thanks.
It works well with VS2013

I didn't find the OpenGL option in v2.8beta

I picked a point from inside(perspective mode and camera center inside).

But when I zoomed out, I found that the picked point was in fact a outside point

Yes, I compiled CC 2.6.3.1 32bits. Is there a lot of difference with 64bits?

I tested with open source CC(2.6.3.1 32bits) and the installer version(2.6.2 64bits). I find the problem occurs just in the opensource version.

Yes, that's it. Thank you so much.

I add a scalar field and set scalar values by a pushbutton. The values are changed but histogram is disable.

Can we set the rotation center of view by a mouse click?
can operation mode "PICKING_ROTATION_CENTER" do it? If yes, how to enable it?
