Nerox Posted June 19, 2009 Share Posted June 19, 2009 Maybe I'm just stupid but I just can't find the Point Cloud Write vex node. This is a Vop right? I would like to write a pointcloud to disk, so I'm able to use it in a Vop due to closesest points/ neighbours stuff. But it seems the pcopen needs a pointcloud file, through the forum/help I figured I need a Point Cloud Write node. But for what ever reason I'm not able to find it.

You write your points out in SOPs as either a .pc or .bgeo file and then the PC Open reads that file in. If you are doing the point cloud in anything but a shader context you can also use op:/obj/geo1/myNode which will read in the points without having to write them out to disk. If its a shader, then you do have to write your pts out to disk. Quote Link to comment Share on other sites More sharing options...

But apart from that, why is there a Vop described in the help, that it isn't there? Wile there are others (according to the point cloud stuff), that aren't mentioned at all? Any way, I'll give it a shot. Thanks SpencerL! Quote Link to comment Share on other sites More sharing options...

This is a wrapper for the pcwrite() VEX function. It lets you write point clouds from inside a shader, and is used heavily by the pyro shader, for example.
