Point Cloud Filter VOP node

This node filters the points queried by pcopen.

On this page

This node filters points queried by pcopen to produce an averaged result. The pcfilter VOP invokes the underlying pcfilter VEX function.

pcfilter takes the points that were opened by the point cloud and produces a filtered value. The following equation shows how the individual points are weighted.

w_i = 1-smooth(0, maxd*1.1, d_i);

maxd is the farthest point, and w_i is the weight for a given point at distance (d_i). Points that are closer to the center will be weighted higher with that formula, rather than it being an average.

Inputs

handle

The point cloud handle to be used for filtering.

channel

The channel name to be filtered.

Outputs

value

The filtered value. The pcfilter VOP will filter using a smooth falloff with distance from the lookup point.

PointCloudLookup Example for Point Cloud Iterate VOP node

This example shows how to accomplish point cloud lookups for volumes using pcfilter and pciterate. It demonstrates how to iterate over and import values returned by a query.
