happy new year!
here is the question . I have many text boards to show.
1 which is better way to save memory , create a Object3D for each text or create only one Object3D for all of text?
2 if i created only one Object3D , how to hide part of this Object3D ? I have tried get polygon id and using setVertexAlpha(polygonid, alpha) to archive this effect. it seems not work verywell,
only first of call is work. (this problem only on android )
I would use several objects. Everything else just adds a lot of complexity without any actual gain. If you are worried about memory usage, you could share meshes and compiled data between these objects and/or create an object pool for these objects.
