Hi Peter and list,

Hi Husk

I finally had time to explore extended view  toolkit and it's
really working well...congratulations!
There is something still I miss: how the texture coordinates works.
What units do
they uses?

The units used for texture-coordinates are pixel.
As you can see in the example you mentioned, all 3 projection modules get their texture information via the (texture id)-outlet from the framebuffer-abstraction.
Now, the framebuffer愀 size is given in pixel, here 1024 by 1024, so if you want a projection-module dispplay the whole framebuffer, its texture-coordinates should range from 0 to 1024 to display the whole content of the framebuffer.
If you now introduce a second projection-module and you want both displaying a portion of the framebuffer, say, one should display the left half, the other the right half of the whole framebuffer,
you have to set the texture-coordinates ranging from 0 to 512(x) for the left half, and to 512 to 1024 for the right half of the framebuffer.
I hope this makes sense to you.
