Flycam

The following instructions were graciously provided by Runitai Linden. Note that since the flycam is in the Client menu, while it's a somewhat-hidden gem, it isn't a formally-finished feature.

How do I get to the flycam?

Client menu (Ctrl-Alt-D) > Joystick Flycam.

Instructions

I've tried to write something up a couple times, but it comes out in geek-speak.

Basically, you have up to 6 axes you can bind to various actions:

  • Move camera up/down (Y-Axis)
  • Move camera left/right (X-Axis)
  • Move camera forward/backward (Z-Axis)
  • Turn left/right (yaw)
  • Look up/down (pitch)
  • Bank left/right (roll)
  • Zoom in/out

The little output graph shows you the values second life is getting from your joystick on which axis. Take the number of the axis you want and set the action you want it to go to to that axis number. Set an action axis to -1 to turn the action off.

The dead zone value tells Second Life to ignore values below a certain threshold to avoid drift. The scale value is like sensitivity.

There was a wonky device I tested against that pretended to be a 3D mouse, so it would give values as cursor positions instead of push amounts, so I made a "3D cursor" check box that interpreted that device properly. For "direct zoom," values from the joystick are mapped directly to your FOV instead of being treated as a delta.

Auto-leveling will try to keep the camera up vector sane.

Last but not least is feathering. Setting the slider all the way to the right will make the camera very rigid, giving complete control to the joystick. Setting the slider all the way to the left will make the camera very fluid, like the camera weighs a lot, good for fly by shots, not good for framing.

I tested on a logitech cordless rumblepad 2 (PS2 controller clone) and got some great shots, but with only 4 axes, I couldn't move straight up or down. The device that started this whole mess was a 3D connexion 6-axis controller, so the camera works well with it, but I'm not fond of the device.

Enjoy!

NOTE: re the Flycam and the 3D-Connexxion SpaceNavigator

I made mine work (on Windows XP) by installing, configuring, and calibrating per the factory instructions, starting SL, and selecting the Client -> Enable Flycam option. A popup appears... and my screen went wonky :) But after fiddling quite a bit I was able to operate using these settings:

First, this is a "3D cursor", so check that box. Then, check "auto-level", un-check "Direct Zoom", and set "Feathering" all the way to the left. Start here:

            x          y          z        yaw         pitch       roll     zoom
mapping     0          2          1          5           3           4        -1
scale      .05        .05        .05       .02          .05         .01        0
deadzone   .01        .01        .01       .01          .01         .01        1

After this, restart the application and re-enable Flycam. This should operate, roughly. I found it helps to slide "Feathering" right a bit and tweak the control. Keep moving it rightward until in "bounces", then back up a touch. The "Scale" velues need to be lots different for moving around a person in a room than they do for moving around a sim :( This is way not as flexible as the mouse moving the camera. That said.. search for the "RBC9" driver, which I've yet to try. It really needs to start slow and to accelerate over time...
