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 framebufferŽs 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
