Sorry for unclear topic name.
I want to do somethings like the following picture.

The problem is that I don’t know how to make background transparent to see through the previous scene background and
show some model ( like the book in the picture ) which can rotate etc …
I know that I can use nifty to set Screen as transparent one , but the model will be draw behind the Screen too.
So , what should I do ??
Sorry for my English and Thank you in advance
In this case the libraly background image is rendered first, then the 3d model, and then the HUD. You’ll need 3 viewports. Look at TestMultiViews.java. Also, take a look at this topic http://hub.jmonkeyengine.org/groups/gui/forum/topic/how-to-add-a-3d-screen-in-nifty/.
thank you
but what if the background is not image, but it is the real previous scene?
Or should I take a screenshort from the previous scene and set it at background image for the new scene one ?
No you move the book to the new viewport that glauco suggested.
@glaucomardano. If I do what you tell, the viewport’s background that show 3d model still not transparent to see through to the background image, so what should I do?
thank you very much:)
separate viewports. not one other viewport where you do the same as in the first ^^
Sorry I don’t understand
suppose this is the code , assume that the library backgrond are attach to the main Camera’s viewport ( that come from Simple Application )
[java]
Camera hudCamera = app.getCamera().clone();
Camera 3DModelCamera = app.getCamera().clone();
Camera HudCamera .setViewPort(0, 1, 0, 1);
Camera 3DModelCamera .setViewPort(X1,X2 , Y1, Y2);
this.HudViewPort = renderManager.createMainView(“HudView”, HudCamera);
this.HudViewPort .setClearFlags(true, true, true);
this.HudViewPort .addProcessor(niftyDisplay); //for init Hud and suppose this line attach hud to the screen
this.3DModelCamera = renderManager.createPostView(“ModelView”, 3DModelCamera);
this.3DModelCamera.setClearFlags(true, true, true);
this.3DModelCamera.attachScene(3Dmodel);
[/java]
the background of 3D Model is Black.
So, what do you mean " separate viewports"
Thanks for quick reply
a) if you clear the buffers (clear flags) then it surely will be black, yeah
b) Why you create a post view? Create a main view.
Wow thank you very much. I can do what I want now. Anyway could you explain what Stencil and depth is, or do you have any resources relate to this ?
Thanks Again
