It is now possible to define one viewport per RenderPass . See RenderPassConfig.setViewport().

For those, who don't know, what a viewport is: A viewport defines a virtual rectangle on the Canvas3D and is handled by the renderer just as if this was the whole canvas. So everything gets translated and scaled (affine transform) to fit into this new "virtual screen".

Great work (as always). Thank you !

I suppose, if viewports are overlapping the one which is seen is the latest rendered ?

The order in which they are rendered is exactly the order of the RenderPasses. Each viewport is attached to exactly one RenderPass.

So how would I use this??  A separate scene??  For example a a user walks through my world in a FPS display, I could have an overhead camera of the entire map??

Yeah, good example .

In my own game I needed this feature because previously I have multiple Canvas3DPanels on a JFrame (not overlapping). One showed the entire solar system and one showed one planet in detail. Then a HUD is drawn over the whole canvas. So I have three RenderPasses, where the order of the first two ones is irrelevant. They are sized smaller than the canvas and don't overlap. The HUD's RenderPass'es viewport is Canvas-sized.

But I think, there are several ways, where this viewport thing could help.

Remeber, that the layered/non-layered behaviour of the RenderPasses also comes into effect for the assotiated viewports.
