as I have seen in the slideset of
http://www.sgi.com/software/performer/presentations/geometry/sld012.htm
there is some interpupil distance correction proposed, depending on the
scene size you are currently
observing.
So my question is: I have a big scene, and need while overflying a
stereo impression.
But as I come close, that interpupil distance is too big for proper
stereo impression.
Till now, I need to adjust the interpupil distance manually.
So is there some algorithm, which adjusts this distance automatically.
For a fast implementation, I thought, I could use the "ray-picking" with
a diameter of 0.5 or bigger.
So the closest object will determine the eye distance via some
heuristics.
Anybody experiences?
How is the performance on the useage of the closest distance obtained by
raypicking?
Or should I use some results of the cull process ?
Which interpolation function should I use for coming close - linear -
quadratic ?
Anybody sample code ?
Thanks in advance
Günter
