Hello,
I'm developing an iOS app with ARKit and SceneKit, where a point cloud is shown in AR. For this, I create a SCNGeometryElement with SCNGeometryPrimitiveType.Point as type and a SCNGeometrySource with SCNGeometrySource.FromVertices. This way, the resulting points are added into the AR as spheres, which results in holes between the elements, even if it is a dense point cloud.
Is it possible, to change the shape of those points to e.g. cubes, so that a dense cloud would close the holes? I've already looked into SCNShaderModifiers and SCNPrograms, but I could not find a simple solution to change the appearance of those points/spheres, without having to create a huge amount of nodes or geometries, which would lead to performance issues.
I hope that you can help me with this problem. Thanks!
