RE: [OpenMap Users] calling OpenGL program from Openmap bean

Kedar,

 

JOGL is simply a binding for OpenGL, which means two things: (1) it’s no
easier to use than OpenGL (which has a somewhat steep learning curve), and
(2) it does not have problems with 3D, in fact, some would argue 2D is more
difficult than 3D in OpenGL.

 

In order to take advantage of your plot being 3D, you’d most likely need to
be able to rotate the “camera” around freely, which is not something you can
do in OpenMap (though I’ve heard on this list before that there is some beta
3D work being done, but I’m not certain).

Hi Carsten,

 

               I want the plot to be 3D, both the links you gave are only
2D. when i googled about JOGL i found it supports 3D too, but i dont know
how complicated it would be?? I would appreciate if you can tell me abt
JOGL( i mean, is there any support for JOGL like mailing list or forums....
Does JOGL has problems with 3D???).

 

thanks a lot,

kedar

Hi Kedar

You can use JNI to access C code from java. We have done this. For an
example go to http://navicon.dk/AIS/aarhus.html the chart layer is done
with JNI/C/OpenGL.

You could also use JOGL to do the OpenGL stuff within Java see
http://today.java.net/pub/a/today/2003/09/11/jogl2d.html
