VRML Server renderer for Unix

Hello,
we have a web application where a VRML model is dynamically generated
(for a visualization of abstract organizational structures).
Now we suggest that site visitors install a VRML client (like Corona)
in order to view the 3D models, but some can or will not do so - for
those we want to offer selected views from the models as automatically
rendered bitmaps (png or jpeg).

So we are looking for a commandline-driven VRML-renderer that we can
install on our Linux server. Thanks for hints !

Did you tried to install xvfb (the virtual X11 server) and run FreeWRL
in the snapshot generating mode on it ?

When off, window operations involving the right mouse button are

The snapshot mode in FreeWRL looks like a good idea - I don't
understand now why we need X11 but the wisdom might come with age -
thanx !

Hi

if a Windows versions would be applicable you could use Bitmanagement
Contact
embedded in a standalone executable with the version supporting Render to
bitmap of arbitrary size and render to Video functionality.

"Did you tried to install xvfb (the virtual X11 server) and run FreeWRL
in the snapshot generating mode on it ?" - I use:

Xvfb :1 -screen 0 1024x768x32 &
freewrl --big --keypress .vsvsvsq my.wrl

Where "my.wrl" has three predefined viewpoints at which I want to take
three 800x600 pixel snapshots with the status bar turned off and then
quit. This does not work as expected because keypresses are handled
without "pauses". (eg. code from "CFuncs/MainLoop.c")

/* handle any events provided on the command line - Robert Sim
*/
if (keypress_string && isURLLoaded() && (!isTextureParsing()))
{
char* c=keypress_string;
while (*c) {
do_keyPress(*c,KeyPress);
c++;
}
keypress_string=NULL;
}

I could add a patch to insert pauses so the command line would be:

Xvfb :1 -screen 0 1024x768x32 &
freewrl --display :1 --big --keypress .vpspvpspvpspq coreworld.wrl

Note the "p" between each keypress and also the "--display" option to
select the Xvfb display. Maybe the "--display" option can be done
without changing freewrl?

suggestions appreciated!

Thanks,
