A mod on wormhole flowfield

markofkane · Post by **markofkane** » Mon Jan 22, 2007 12:17 pm

I don't get it.

Round?? I try replacing rnd with round, same result.

Version?? 100 seems to work on other flowfields. I have the latest beta.

Error while compliling srcR

No. The new syntax allows for the full word round to precede the simple (rnd). My guess is that (rnd) is no longer allowed/applicable *within* parentheses? And Maybe (round) is used as a randomization booster? I'm not familiar with the new code at all; so my help here may be in vain.

A2 example:

A2= "A1 - (-2) * round(rnd(.03) + .01)"

Edit: srcR issue? Try junking (abs).

I think that worked. Geez, I wish I knew what it all meant.

So do I.....................................

You now say it worked...

Can you post a screencap and I'll tell ya if it worked?

whoops. spoke too soon, testoftests worked, but not the modified version:

Aspc=1

A0="D1/.29" // Max r, the greater the denom, the more of the first effect is visible

// First effect params
A1="rnd(20) + 20"
A2="a1 - (-2) * (round(.03) + .01) " // Flow Speed
A5=" rnd(.1)"
// Second effect params
A3="1.985" // Flow speed
A4="2.22" // Rotation speed

// Interpolation of first effect to second according to r
D0="exp(-r*A2)" // 0..1 Interpolation factor
D1="wrap(1-a4) " // 1..0

// Take an image of the current situation, inside this radius
srcR=" r * trwv(abs(1 - clip(r) * A2) + sin(theta(D1 + A2 * r) * D1) )"

// Rotate the image a bit
srcT=" theta + abs( sin(y * A2) * A5 * D1 ) + sgn( cos(r * A4 ) * D0 ) "

Vers=100

::argh::

See my above suggestion with junking abs in the R code line.

Still problems.

How bad did I muck it up?

Aspc=1

A0="D1/.29" // Max r, the greater the denom, the more of the first effect is visible

// First effect params
A1="rnd(20) + 20"
A2= "A1 - (-2) * round(rnd(.03) + .01)" // Flow Speed
A5=" rnd(.1)"
// Second effect params
A3="1.985" // Flow speed
A4="2.22" // Rotation speed

// Interpolation of first effect to second according to r
D0="exp(-r*A2)" // 0..1 Interpolation factor
D1="wrap(1-a4) " // 1..0

// Take an image of the current situation, inside this radius
srcR=" r * trwv(1 - clip(r) * A2) + sin(theta(D1 + A2 * r) * D1) )"

// Rotate the image a bit
srcT=" theta + abs ( sin(y * A2) * A5 * D1 ) + sgn( cos(r * A4 ) * D0 ) "

Vers=100

I tried removing the second abs, then I get 2 errors. So I put one back.

My kingdom for a happy medium....

I would check with Andy. I am sure a couple of years ago (when I first did GF configs) I mentioned this and I thought that he didn't want, in general, too many postings of configs on the boards as people coming to the forums would get confused. I suggest another forum then I'm sure.

Maybe I misunderstood what he meant (I ignored him anyway

)

Ah....I notice now that we have five closing parenths in your R statement as opposed to four opening ones. Chuck the one at the very end and see what gives.

Then go back *four* posts and re-write your entire srcR as shown there. We'll get to the bottom of this yet.

Unexpected token is the error after removing the extra )

Aspc=1

A0="D1/.29" // Max r, the greater the denom, the more of the first effect is visible

// First effect params
A1="rnd(20) + 20"
A2="a1 - (-2) * (round(.03) + .01) " // Flow Speed
A5=" rnd(.1)"
// Second effect params
A3="1.985" // Flow speed
A4="2.22" // Rotation speed

// Interpolation of first effect to second according to r
D0="exp(-r*A2)" // 0..1 Interpolation factor
D1="wrap(1-a4) " // 1..0

// Take an image of the current situation, inside this radius
srcR=" r * trwv(abs(1 - clip(r) * A2) + sin(theta(D1 + A2 * r) * D1) "

// Rotate the image a bit
srcT=" theta + abs( sin(y * A2) * A5 * D1 ) + sgn( cos(r * A4 ) * D0 ) "

Vers=100

I tried removing abs, and got same error as in the beginning.

It works (maybe not as intended) this way:

Aspc=1

A0="D1/.29" // Max r, the greater the denom, the more of the first effect is visible

// First effect params
A1="rnd(20) + 20"
A2="a1 - (-2) * (rnd(.03) + .01) " // Flow Speed
A5=" rnd(.1)"
// Second effect params
A3="1.985" // Flow speed
A4="2.22" // Rotation speed

// Interpolation of first effect to second according to r
D0="exp(-r*A2)" // 0..1 Interpolation factor
D1="wrap(1-a4) " // 1..0

// Take an image of the current situation, inside this radius
srcR=" r * trwv(1 - clip(r) * A2 + sin(D1 + A2 * r) * D1) "

// Rotate the image a bit
srcT=" abs( sin(y * A2) * A5 * D1 ) + sgn( cos(r * A4 ) * D0 )"

Vers=100

'MKay...big own-up coming...

My original countertweak for Test of Tests had a problem on my part with a misuse of theta. I'm gonna start fresh and work from there.
