thanks c!

way simpler than I thought :)

Could you explain a little more how you achieve the motion blur?
i.e. what do you mean with "just render 10 primitives for every image..."?

thanks!

Hi all,

I have a 1900 x 800 gemwin. I render a few geos on a big [sphere] and a 
pmpd system on top of it.

I'd need some cpu-friendly motion blur and glow effects on everything 
rendered in the gemwin.

My strategy so far has been to split the final rendering into two 
800x800 squares. That is:

I have two [snap2tex] snapping two separate [gemwin -1] onto two 
[square]. One [snap2tex] has 0 0 offset, and the other has 800 0 offset. Then, 
by modulating the opacity of [colorRGB] for the 2 squares I can get motion blur 
effect.

This works fine, but the same splitting strategy doesn't work for 
shaders. If I apply a shader to the two [square] the coordinate of the texture 
are all mixed up.

Also, when applying the shaders the cpu go up +30%, whereas [snap2 tex] 
takes way less resources. is that normal?

What's the best way to go here?

thanks!

Hi Cyrille,

ok, I now managed to use gemframebuffer in a smaller test patch. For some
reason, in my larger patch it crashes everytime I connect it to the pmpd
system. Had to use [scaleXYZ 0.5 1 1] to fit the rectangular dimension of
the gemwin.

Could you explain a little more how you achieve the motion blur?
i.e. what do you mean with "just render 10 primitives for every image..."?

Re: [PD] strategy to apply shaders/motion blur to pmpd in a 1900x800 rectangular gemwin

[Cyrille Henry]

hello Marco,

better than snap2tex, you can use rendering in framebuffer. The framebuffer can 
directly be rendered as a texture, no snapping is needed.

i did not understand the way you make your motion blur.
I  usually have my model to run at a frequency 5 or 10 time faster than the 
rendering. then, you can just render 10 primitives for every image...
or make 10 rendering per frame, and average them in the final render.

[PD] strategy to apply shaders/motion blur to pmpd in a 1900x800 rectangular gemwin

[Marco Donnarumma]

Hi all,

I have a 1900 x 800 gemwin. I render a few geos on a big [sphere] and a
pmpd system on top of it.

I'd need some cpu-friendly motion blur and glow effects on everything
rendered in the gemwin.

My strategy so far has been to split the final rendering into two 800x800
squares. That is:

I have two [snap2tex] snapping two separate [gemwin -1] onto two [square].
One [snap2tex] has 0 0 offset, and the other has 800 0 offset. Then, by
modulating the opacity of [colorRGB] for the 2 squares I can get motion
blur effect.

This works fine, but the same splitting strategy doesn't work for shaders.
If I apply a shader to the two [square] the coordinate of the texture are
all mixed up.

Also, when applying the shaders the cpu go up +30%, whereas [snap2 tex]
takes way less resources. is that normal?

What's the best way to go here?

thanks!
best,
