can a serious 3d game be made entirely in Java?

if so, what would be the minimum specs of the development computer and would i use an applet? if i was designing the game with a console in mind, what would be the best route?

javagaming.org has much stuff, I'm not sure if it's all pure java. Java itself is optimised for your specific PC, so it runs faster than generalised C, the problems are that it takes ages to just-in-time (JIT)compile each time the program runs and when a new object is loaded.

Also if you want speed then don't use java's libraries, they are bloated for function and compatability, not stripped for speed and RAM usage

So technically, java games should be faster than C/C++ games, it's just that java isn't designed with games in mind

If you really want fast, with no JIT time, try writing an assembly program for each platform/processor combination.

Java *can* be optimised for your specific PC, its all down to the VM. It is only theoretical however, as there are no platform/processor specific optimisations I know of in Suns VM.

well written C will always be faster than Java.

yeah, but the extensivness of the Java libraries is one of the languages major strengths - without them, there is even less reason to use Java over C[++].

'Java isn't designed' :]

This topic comes up roughly once a week- take a look through the archives.Sturmovik is not entirely written in Java- the engine and much of the rest of it is C++- it just uses Java for much of the scripting, a bit like Vampire: Redemption and many others.

Existance proofs:

JAMID, J3D Grand Prix, RoboForge, GetAmped, Law and Order

The last three are all commercial releases. RoboForge and Get Amped have

received fantastic magazine reviews, Law and Order is in Beta. All but GetAmped use Java3D,

(GetAMped uses a OpenGl binding but otherwise is pure Java.)

By way of annecdotally answering your second question, We showed Java 3D Grand Prix (a game that loosk at elast as good as this year's GP game from EA) at CGDC running at 60fps on a 1.4 ghz machine with 256meg of memory (though it will work just as well in 128) and Geforce3 GTS.

The same machine ran JAMID at over 110fps.
