Hello Everybody,
I need to implement a 3D-Geoinformationsystem-Service in a 2D-GIS.
I have already written a Mapper for Shape3DObjects in my thesis.
The problem now is, that the performance is really slow. Okay I know, by
now I didn't took much care of performance-like programming.
So I have got several questions:
- What kind of complex applications did you test with Java3D? What are
your expierences with it?
- In general, what is Java3D capable of?
How much speed do I loose with Java3D in complex
Java3D-applications versus OpenGL-Programs?
I need to implement scences with digital elevation models
with several 100 to 1000 polygons
and I want to navigate in these scenes and interact with these
scenes, can Java3D handle this for professional users?
Can I reach for example similar performace like the Arcview 3D
Analyst?
- Which kind of Graphic card is good for using Java3D with WindowsNT?
- How can I make sure that my Graphic Card in the moment is using its
hardware accelaerator (it's a Permedia 2) ?
Has anybody experience?
Is it possible to get windowed hardware acceleration for my
application, and what do I have to do to achieve that? Do I have
to reset the resolution of the monitor or do I have to reset the
size of the Canvas3D Frame?
- My impression is that my prototyp-application is using much space of my
memory, is this more likely a problem from Java3D or from my programming
style?
- When I change my way of programming in point to performance do you think
Java3D is capable of handling a real complex application with 100- 1000
points - objects with a reasoable performance?
Please, answer some of my questions I really need your expierence with
Java3D? This will be very helpful for me!
Thanks for any help in advance
Yours Desiree
