Very helpful thank you

can you offer any advice using expressions to add further randomness to the movement of the circles.

I believe that the cell pattern effect is a random distributionon a frame by frame basis, wheras the circles in cc ball appear to move on a path or a walk.

many thanks

Paul

Many thanks Kalle this is very helpful.

To explain: I want to replace the standard random number generator with several PRNGs (pseudo-random number generators) including the one listed above (a Halton sequence)

My project involves using the cell pattern effect to produce animated noise fields consisting of single points.
The different PRNGs should produce different distribution of the points within the noise field. Ideally I would use the expression to replace the random seed in the effect.

do you think this sounds like it will work?

[Paul Rijkaard]

I would like to produce several PRNG’s to be used as utilities in after effects.

Would it be possible to translate the pseudo code below to work in expressions?

FUNCTION (index, base)
BEGIN
result = 0;
f = 1;
i = index;
WHILE (i > 0)
BEGIN
f = f / base;
result = result + f * (i % base);
i = FLOOR(i / base);
END
RETURN result;
END

That’s great to know, can you direct me to any resources which would help explain how to develop functions?

Brilliant, thank you very helpful

Brilliant, many thanks – I have the footage imported with alpha – looks good, but the image is still and not a video.

I have imported the video into materials: colour: texture

do I need to do anything to activate the video?

thanks in advance

ok thanks, just to make sure I have explained myself fully, I would like a spot light to pivot and move with the same coordinates as a solved camera. I think, this is not the same as a tracked object, but I am probably wrong??
