Smooth pan jumps

Is there currently a way to script smooth pan jumps from one view to another ?

If not I`d like to request the option. With more people making hires gigapixel images showed with KrPano we need better scripting of the viewer to show various points of interest in the image.

If you have a look at the Dresden image youll see that pan jumps follow a linear motion thats less than optimal: http://www.dresden-26-gigapixels.com/dresden26GP Click some times on the various point of interests, and then have a look at this Silverlight case and youll see the difference in user friendlyness: http://blogs.msdn.com/lutzg/archive/…animations.aspx

Here's a problem: I want to pan smoothly from one area in a map to another. One way to do that is simply update Viewport Origin and ViewportWidth and let Deep Zoom handle the transition animation. Unfortunately that will lead to animations that look like you are traveling at the speed of light across the globe if you have large distances to cover.
Ideally, you'd want to zoom out a tad bit, nudge over a bit, and zoom back in. Well, thanks to Dan Cory and James Darpinian, we have such a solution. Based on this paper, we implemented this.

Heres a paper on the subject: http://www.win.tue.nl/~vanwijk/zoompan.pdf

Theres also this paper: http://www.cs.umd.edu/hcil/jazz/lear…-spacescale.pdf

Is this possible in KrPano ? If yes it will make the viewer much better suited for hires panos and zoomable images.

May there be a way to make a "pseudo" effect like the effect proposed by some smart scripting ?

Is it possible to do with movto type smooth ? If yes, are there any examples online ?

moveto(toH,toV,motiontype)
zoomto(fov,motiontyp)
lookto(toH,toV,fov,motiontype)

moves the view from current to the given position

parameters:

• toH
  destination coordinate (-360 .. 360°)
• toV
  destination coordinate (-90 .. +90°)
• fov
  destination field of view (1 .. 179°)
• motiontype (optional)
  can be:
  linear(speed) - linear movement
  - speed = moving speed in degrees/second
  

  smooth(accel,break,maxspeed) - accelerated smooth movement (=default)
  - accel = acceleration in degrees/second² (default=720)
  - break = negative acceleration in degrees/second² (default=-720)
  - maxspeed = maximum moving speed in degrees/second (default=720)

examples:
moveto(100.0,5,linear(10));
zoomto(130,smooth());
lookto(33,-22,30,smooth(100,50,20));

The very basic GigaPan zooming interface also have smooth pan jumps: http://www.gigapan.org/gigapans/7746/

Is this something that may be achievable via a plugin solution ?

I guess the best way to "jump" between two positions in multires panos would be to "zoom" out quit a bit, possibly up 60-75% of max fov, from the current position, and then have a smooth "jump" to the new position using the remaining fov and then zoom in.

How does the caching work ? Will higher levels of the pyramide be cached whan at a specific position/fov ? If you examine the GigaPan viewer youll see that it doesnt work very well cause it has black tiles while trying to do is smooth trajectory.
