Hi everyone,

I have an output from a PointCloudCombiner with 4 components (x, y, z, _distance). The _distance attribute comes from a NeighborFinder. What I want to do with the point cloud is to replace the z component of each point by its _distance value. I tried to use the PointCloudExpressionEvaluator after the PointCloudCombiner but _distance doesn't appear in the component list. I only have access to it as an attribute (not a component) and then get the same z value for each point of the point cloud... But when I check the PointCloudCombiner output in DataInspector I can see by clicking on each point that there is a _distance component that changes with each point. How can I have access to this component for further processing ?

Thanks !

In the PointCloudExpressionEvaluator set the expression to @Component(_distance).
