I have a PackedVector3Array that stores Vector3 coordinates in the shape of a sphere. I would like to load individual meshes at these points when a player is within range of them. What would be the best way to go about doing this?

I recently watched this awesome video, where they load in stars using blocks of world space. I think what I would like to accomplish is something similar to this, only my "stars" are the predefined points along my sphere, so not random.

I would like to load a mesh when the player comes into proximity of a vector3 point in the array, how could I set this up?

  • dizzy The amount of points is scalable

    Sure but you need to have a ballpark. If the limit of points is relatively low, you can get away with linear search. Otherwise you'll need to employ one of the recursive space partitioning schemes, like k-d tree, bsp tree or quad tree.

      dizzy changed the title to Proximity Loading using Array of Vector3s? .

      dizzy How many points? Are they only on surface of the sphere or anywhere in the sphere?

          xyz The amount of points is scalable, only on the surface

                  xyz Apologies, yeah there's too many points for linear search. Going to look more into recursive space partitioning, but from what I'm understanding I can use the players location to mark their 3D quadrant, and then find all the Vector3 points inside of that quadrant?
                  Either way I was able to find this video tutorial, which I can see helping me out a lot so thanks for pointing me in the right direction!
