Oops, I didn’t notice the update the blog post before posting my last comment. I should pay more attention…

I don’t think it matters whether the vectors are immutable or not: from what I can tell, their reason for being immutable is because they need to be explicitly written back to the VectorList with the set method (in other words, reducing the memory foot by packing x,y,z into a float[]). All operations on the vectors return a new instance. A similar solution, but perhaps slightly cleaner, is employed here: http://mechanical-sympathy.blogspot.se/2012/10/compact-off-heap-structurestuples-in.html – naturally for vectors, and other objects packing identical primitive types, it’d be easier just storing the data in an array like the VectorList does.

Personally, I do most on my gamedev for android, so I have to resort to object pooling (meh…) or manually packing the data into primitive arrays.

Thanks for the reply! I did know about this it never knew it could work this well, nice! But the thing is, we only use pooling at places where the visual vm finds a lot of allocations and we would never even considered it in the first place if it wasn’t a problem for us:)

But looking at your example the main difference is probably that those vector classes are completely immutable while ours are not. I guess I’ll experiment with this as well:) It it still works in more complicated scenarios it definitely preferred over pooling.

Thanks again!

Peter

Nice post!

As long as you’re developing for the desktop, there rarely is a need for object pooling as recent JVM:s can expand small objects on the stack (by virtue of scalar replacement) – see this post for more info: http://www.stefankrause.net/wp/?p=64

There are some forces pushing for structs in java (and operator overloading!), don’t think we can expect it anytime soon though: http://medianetwork.oracle.com/video/player/1785452137001 – structs are something I sorely miss…

I think in reality PC’s have been called dead for the last 15 years – and are doing pretty well still as gaming devices. They won’t go anywhere. We’ll definitely support PC: windows, mac and linux.

My pc is my core gaming rig, I hope the industry will keep paying attention to pc gamers even if it becomes a less popular gaming system.

Interesting idea. Nice way to add some raison d’être.
