Re: [JAVA3D] Why is JAVA3D sooooo slow ???? please help

[Enrique Dumas]

ola keep cool !

I never wrote that jogl or gl4java have no bugs or limitation ...

 

weekend projects ?

hum not sure...

All 3D projects do not require a high level api as J3D ;)

 

Do you know this demo ?

http://java.sun.com/products/jfc/tsc/articles/jcanyon/

 

Well J3D is great and I respect all Java3D team for their great work ;)

 

But before starting a project with a 3D engine we have to check our needs and after take

the best api do to the job !

 

So there are lots of cool demo and projects wrotten in pure opengl , so when the application is too complex it's better to use a 3D engine

 

I think that to show integrated circuits designs in 3D it can be interesting to start

with an opengl wrapper, so overlays will be easier to do

um....
sorry if i call a spade a spade.

With all due respect to the Java3D team at Sun, it is MUCH HARDER to
write an abstration layer such as Java3D, than a mere wrapper such as
jogl or gl4java. Those little guys are weekend projects compared to
Java3D. Java3D has come a long way, and is quite mature. Who knows
what it was like years ago. Basing your judgement on years ago...
well.. you deserver what ya get ;)
