[openvrml-develop] Loading and displaying different models in the openvrml viewer

[Jean-Nicolas O. <jno...@gm...>]

Hi,

I am developing an application where I display a wrl model from a custom
viewpoint in opengl, similar to what is done in artoolkit. I built the
latest version of openvrml (0.18.99 for now) along with the dependency and
successfully integrated it in my application. I use a custom viewer
(myViewer: openvrml::gl::viewer ) and I can display one model without
problems. The model is loaded from the browser load_url as in the sample
sdl_viewer. I use the render function to display the vrml model.

Now I want to display more models pre-loaded from different wrl files
dependeing on the user interaction with the application. Is there a simple
and efficient method to accomplish this. Digging in openvrml source, I found
the viewer::replace_world which seems to do this but I don't understand the
documentation. An example of how to do this would be very usefull. Can
someone explain how this can be done?

Regards,
JNO
