1  Java Game APIs & Engines / Xith3D Forums / Xith3D with multiple Viewports and other questions on: 2004-03-19 06:51:49
Hi there,
I'm just a newbie with Xith tech, i've looked through the API, the forum and the source code. I've previously developped several little applications using OpenGL, and i'd like to pass to an completely Java application with high level abstraction layer just like Xith3D ! cool Grin. But this is not the subject of this post.

First, I was wondering  how i could use multiple viewports in a single Java Frame. Is there any way to do this, such as sharing the same Canvas3D with multiple View ?
This way one can use the same technology to draw the *real* scene and any other small windows such as local map, character preview, and so on.
If it's not possible, what is the right way to implement it ?

Secondly, i really think that DisplayList usage improve performance for static data or transform. I think because of the SceneGraph, their usage and maintenance may be hard, but is there any way to use them, like specific Node compilation ? What should be the right place to plug them, actually i've not really understand the RenderBin process and how they are fill, and processed.
I've read about shader, but i don't really understand what it is, does it aim to give a similar purpose that compiled stuff just like DisplayList?

Finally, i'd like to implement the multiple geometries feature on Shape3D (fo JOGL implementation). Right now, only one (the last) is taken into account, does only the Shape3D and it's peer *ShapePeer* class need to be modified.

Thanks,
(sorry for my english...)
