[Plib-users] passing more than one value to psl scripts

[Gerald F. <gf...@tu...>]

Dear plib community,

I am currently evaluating several scripting engines on their 
suitability for controlling simple animations in our VR framework ( 
http://velib.kyb.mpg.de ), and psl seems to be a promising candidate 
due to its small footprint and support of massive quasi-parallelly 
running scripts. For our purposes it is necessary to pass each frame a 
   larger number of variable values (e.g., 6 float values containing 
an object's position or orientation or 16 values of a transformation 
matrix) to the scripts. I succeeded in accessing these data 
individually by writing access functions that return just one specific 
ordinate, but I could not find a mechanism to pass a complete array. 
It seems pretty cumbersome and like a lot of overhead to need 6 or 
even 16 function calls for such an initialization.
Since psl as part seems to be designed for 3D applications, I am just 
wondering whether there is a more efficient mechanism for doing that. 
Can I somehow pass an array?
If not, I've found that there is a class pslVariable which already has 
the ability to handle more than one value. If extension functions 
could return such an object, this would seem to me like a more 
flexible solution.

Thanks for any idea or comment
Gerald
