gas field wrangle and point clouds ?

[AME]

Hi everyone.

 

I need to open a point cloud in a gasfieldwrangle - node but i need the point cloud to update for each frame as well. Any ideas how to do this. In the geometry context i would simply wire the geometry to one of the inputs in a volume wrangle node and call the pcopen- function, but I can't this as a possibility in DOPS. 

 

Any help is greatly appreciated

You can add spare parameter then reference that in wrangle.

Or can wire that geometry to DOP Network SOP then it can be access by @OpInput0 or 0 and so on.

 Thanks a lot Pradeep. I tried to implement the stuff you suggested (correct me if i'm wrong) but somehow i still can't make the wrangle node open  the point cloud. I wired a geometry copy node to the input of the gas field wrangle node and wrote:  

 

hnd = pcopen('op:`opinputpath(".", 0)`','P',pos,0.2,99999);

 

as the vex-snippet, where the position is some vector.  It still returns 0 though... I also tried with the absolute path but to no avail.

It should be written as:

hnd = pcopen(0, "P", @P, 0.2, 99999);  // where @P is position can be replaced with @pos

hnd = pcopen('op:`opinputpath(".", 0)`','P',pos,0.2,99999);

 

 

Only full path allowed inside wrangles. Since your Geometry is wired to first input so just put geoself() or 0.
