Rescale noise...?

dandelO · April 19, 2011, 09:07:18 AM

Ahh, great. Thanks very much, Hetzen. That explains why I wasn't able to move my CAMERA with the get frame node!

I had it all mixed up in my head, thinking that you were converting the actual keyframe with the 'get frame number' into a steady movement with a constant, and not just the element of the scene that's moving, I get it now, it's really great, cheers, man!

Mogn, that's cool but it isn't quite what I was meaning I don't think. The pattern isn't actually increasing in scale from the origin outwards. I am having a look at the file you uploaded in this old post; http://forums.planetside.co.uk/index.php?topic=1414.msg14135#msg14135
This seems to be more in line with my problem but where you've altered the noise scale based on altitude, I would like to alter the scale based on distance from the origin(or even better within a 'point A' to 'point B' range).

Cheers folks!

With a look at Mogn's scale-by-altitude setup I've had quite a bit of success!
I can now rescale noise along any direction so that's great. Cheers, man!

Getting there slowly...

Cool!
Could you post a node view for the first one,please?

It really distorts away from the origin badly. In the snapshot the camera is 50m above the ground, any further and the stretching overtakes the scaling.

Or use a divide scalar with an input of 10 instead of multiplying .1.
Probably makes more sense that way.

Thankies!
At least it's a very promising starting point and it shows that
it's possible,so let's play.

Nice progress , DandelO

I wonder if, replacing the gradient with a Perlin somehow, we could use it to vary the scales of a PF.

Getting a bit sidetracked from the whole point I was asking about rescaling noise but it's good fun...

Nice work on all of these! The last one looks really cool!

dandelO · April 19, 2011, 08:04:57 PM

A big shiny one then!

dandelO · April 19, 2011, 09:03:05 PM

That one is a bit ragged round the edges ^^.

Last one for now.

There's far less noise here. It's a smaller image but took the same time as the big one to render. I'll do a bigger one another time at this setting.

Would like to touch it

Looks very nice DandelO!
And thanks for the file!

This is very interesting, Martin. You could well be doing modern church windows! Push a cave into a vertical wall, inset a vertical plane, add a light inside the cave and project your wonderful (and perhaps more colorful) pattern on the plane...

Again very nice!
Didn't find that much time yesterday,but i think i could improve the effect a little bit
by reducing the .1 to .05 or even .025 and then connecting the mixers output to an
add scalar with a constant scalar set to 6 or 9.At least it increased the area of the
effect.But as usual the further away from the 0/0/0 point the more stretching.
Gotta play some more.
