selectWorldPoints

Select world points from world point set

Since R2024a

Syntax

wpSetSelected = selectWorldPoints(wpSet,pointIds)

Description

wpSetSelected = selectWorldPoints(wpSet,pointIds) selects world points from wpSet using the identifiers in pointIds. Use this syntax if you added points using the addWorldPoints function by specifying unique point identifiers pointIds.

Examples

Select World Points from World Point Set Using Point IDs

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
