Hi if i render a scene with multiple views like FourViewsPanelTest example,
 I am not able to set different screen scale to different Views .Say in FourViewsPanelTest i want to see the cube in diffrent size.

It takes default views screenScale values for all views.
Am i missing anything?

Hi, kangaroth

I had a look at the projection matrix calculation of the View. And the screenscale is only used in parallel projection. And I think, this makes sense. Isn't, what you want to achieve, simple done by moving the View closer to the cube?

Hi Marvin  i think that in Parallel projection it does not matter from how far you are viewing.To change the size we need to change the screen scale , it was working like this till xith 8 .
On debugging i found that in set(RenderPassConfigProvider template) of View.java ,all  View's screenScale and other parameters are set what RenderPassConfigProvider params are .
I just commented out 

Code:

this.screenScale = template.getScreenScale();

from this method and now its behaving as expected.

Well, that was, what I said .

OK, I will check that. Thanks for the hint.

This issue is now fixed.

I have created a test case, that does the four views thing with only one View and one Canvas3D, but four RenderPasses (with four different Viewports and different view transforms). It is way faster, and absolutely stable.

Please have look at org.xith3d.test.ui.QuadViewportTest

Note, that the QuadDivider Widget, I used there is extreme-alpha!!!

I think, this is a lot better, than using four Canvas3Ds and Views.

Once again thanks for such a prompt response.

Will try out the org.xith3d.test.ui.QuadViewportTest.It looks tempting if we dont have
to create four different canvases and views.
But if we want four views to be totaly independent say no effect of one View shift ,rotating ,scaling etc on other views ,will four RenderPasses will cater to this need.

Yes, they're independent also in this manner.
