BUG: Camera handle very very slow

Hello,
I have to say, camera blocking in 8 is really really nice. The in-viewport camera handle is really great, combined with the already great camera handle from 7.
Only problem is, I have a scene that is really large (room is 300 units across), and the track part of the in-viewport handle REALLY slow, you have to drag, release, drag some more before you see a tiny move. Tilt works fine though. Basically I can't use the Track handles, which is too bad, since they're really handing for tracking only in one direction, as opposed to locking the camera to the viewport and using the regular Space + Mouse to track.

Also, a less critical problem, the Rotate part of the handle is very hard to click. Often I have to hit Spacebar to nudge it into accepting my clicks.

Not sure it's a bug, per se - perhaps a usability issue. Not sure about the easiest way to set a permanent scaling for those handles. However, the good news is that you can MMB over, say, the vertical transform and get our beloved ladder, and it's easy to move it quickly at whatever scaling you wish.

Hi John,
Forgot to mention, MMB using the ladder causes a big, immediate “jump” and the camera flies off somewhere I don't want it ( First thing I thought of, the ladder )

Odd - doesn't do that here, running both 8.0.391 and (just this morning) 401 on SUSE 9.3, NVidia card. It behaves as expected - it will jump if I happen to hit the “100” scale, of course, but no more than expected. Try it in a virgin hip with a 1000 scale grid and see if it's something that's affecting by some other setting you've done.

This is definitely a usability problem. The problem is that, looking through the camera, you might want to make a small change (in which case it should be more or less as it is now) or a large change (as you're seeing). I don't know if there's a better way than using the ladder handle of fixing that; suggestions gratefully accepted.

I can reproduce the jumping, I think. Peter, could you look carefully and see whether what you're seeing is a double application of the first movement? (I.e., you start at 0, 0, 0, try to move up one 0.1 interval and instead of 0.1, 0, 0 you end up at 0.2, 0, 0).

Yes, I can repro. Missed that…

Hi Joe,
No, the first time I use the Ladder it jumps a long way (from 41 to 45 for example). Interestingly, if I undo, then use the Ladder handle again, I do get what you describe (.1 becomes .3) which isn't so bad. So, I do have a workaround, just undo then use the Ladder handle again and I'm OK.

Adding my 2 cents here.

If the camera's near plane is set very low, 0.001, you get the problem as Peter described. If you increase the near clip to, say, 1000, then the handle interacts better.

This is the same if you try to pan with the RMB when looking through a camera that has a very low near plane value.

This has to be fixed in addition to fixing the jump when using the ladder.

Cheers!

Yeah its weird, like Steve says if you move the near clipping plane up it responds more as you would expect, maybe if it used the far clipping plane as an indication of the scale you were working at then this “bug” could be turned into a feature?
