The pciterate VOP will either start a point iteration or advance to the next iteration point. The pciterate VOP should normally be used as input to a while loop condition, with Point Cloud Import operations inside the loop to gather iteration point information. The pciterate VOP corresponds to the pciterate VEX function.
You should usually iterate through all points in the point cloud. If you don’t iterate over all points, it is necessary to use the Point Cloud Close VOP to close the point cloud before other operations are performed in the shader.
The point cloud handle to be used for iteration.
Returns 1 when the iteration was successful, in which case point data can be queried using pcimport.
