Generate 3-D world points.

worldPoints = rand(100,3);

Generate point IDs.

pointIds = randperm(100);

Create a worldpointset object.

wpSet = worldpointset
wpSet = 
  worldpointset with properties:

                   WorldPoints: [0×3 single]
                       ViewIds: [1×0 uint32]
                      PointIds: [1×0 uint32]
              ViewingDirection: [0×3 single]
                DistanceLimits: [0×2 single]
          RepresentativeViewId: [0×1 double]
    RepresentativeFeatureIndex: [0×1 double]
                         Count: 0
               Correspondences: [0×3 table]

Add the world points to the world point set.

wpSet = addWorldPoints(wpSet,worldPoints,pointIds);

Select the first 50 points in the point set.

points = selectWorldPoints(wpSet,pointIds(1:50))
points = 50×3 single matrix
