Title: Clipping problem with OpenGL ES 1.x
Post by: chetanmrane on March 20, 2013, 04:11:48 AM

Hi,

I am facing clipping issue because of OpenGL ES 1.x.
The clipping works fine with OpenGL ES 2.0

So i dig lot into the forum and found one alternative to my problem...using secondary camera i can achieve scrolling without clipping

My doubt is ...

Can i add two different scrolling bars on single NGUI Page, i mean multiple View Camera ?

What would be the best practise?

Below is basic Ngui Structure i am following:


UIRoot 1
|-   2D Camera [NGUI Layer]
|-    Anchor
   |-    Panel A
      |-   Tile Sprite (with box collider and UIDrag Camera)
         |-   TopLeft
         |-   BottomRight
      
   |-    Panel B
      |-   Tile Sprite (with box collider and UIDrag Camera)
         |-   TopLeft
         |-   BottomRight
   
UIRoot 2
|-   View Camera (with UIDraggable camera and UIViewPort) [default layer]
|-   Anchor
   |-   Offset Panel (with UITable)
      |-   item
      |-   item
      |-   item

GLES 1.1 = no shaders.

No shaders = no clipping.

It's a simple as that.

Thanks ArenMook for your reply

agreed that GL 1 is not supporting clipping

but for that, i am using alternate soultion of secondary camera as in NGUI sample example

my q's is can i used multiple View Cameras for multiple scroller one is horizontal and other is vertical?

if so, then what would be the best heirachy to use it?
