Using spatial hash to determine view distance
I am creating a client/server that is 2D and based on a map. Characters on the server are then separated into a spatial hash. I am using this to determine who to send data to, essentially, people in ...

Can inserting/removing one point in a quadtree or octree cause multiple splits/collapses?
I was reading Robert Nystrom's Game Programming Patterns website and, in the section about spatial partitioning, particularly in the section on quadtrees, he mentions:
Objects can be added ...

3D Binary Space Partitioning with solid/empty leaves
I've recently started looking into BSPs for real-time collision detection, and I'm now looking into improving the performance of my solution.
The system that I've implemented is rather similar to the ...

2D Spatial Hashing in C++ Causing Game to run more Slowly
I'm trying to use spatial hashing to speed up collision detection in my game. I believe spatial hashing is better suited for my game than quadtrees, because I have lots of fast-moving objects in my ...

Does collision detection data structures require a manifold mesh
Is it possible to apply spatial split techniques (oct-trees bsp-trees, etc) when meshes are not necessary manifolds?
The mesh in question represents the "map". This means that it is static so spatial ...

How do I efficiently choose the terrain chunks to render based on the player position?
Well, I have an array with all the terrains. How do I render them? I just add them to a List of terrains that are sent to the Renderer. There, every terrain of the list is rendered.
The problem is ...
