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´s 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.
How do I relate one projection panel to another to share content
between them?
see above
Let's say I want to add a floor to your
04_ev_example_3d.PD: what coordinates I should
put (for example) to connect the floor with the left projection panel?
can you explain further, what you want to do?
Thanks in advance
husk
you are welcome.
peter
