G-Force Equalizer visual?

trev_zz · Post by **trev_zz** » Thu Feb 18, 2010 3:28 pm

Hi,

I’m new to G-Force and have just downloaded the trial version.

I was looking for an ‘Equalizer’ type visual effect and so far the trial hasn’t displayed what I was after.

An example is in this link below and uses a light panel driven by DMX512
Before you click the link make sure your volume is down... or up your into clubs

http://disco-designer.com/Equalizer_panel_video.html

Does anyone know if G-Force is capable or near capable of this

I was thinking of hooking my PC up to a large panel TV for a similar effect

Any help much appreciated

Cheers, Trev

Gf is far more detailed and imaginative than a simple VU meter.

I know the one you mentioned looks pretty but its not really a visualizer in the same sense as GF.

So to answer your question, No GF does not look like that vid and never will.

Has it been done? nope.
Could it be done? Maybe.

First, you would need to TURN OFF Flowfields, Particles, & Sprites
AND run a 'lone' Waveshape.
This is a first stab without concentrating on the nuances of your specific requirements.

(Be kind

, this was unfinished work, I started a while back ... it certainly doesn't represent best and final)

did you look at the vid he posted? check it out, he wants something much different.

GF will never look like that ever! it will never have a window designed to look like a VU meter

jerohm · Post by **jerohm** » Thu Feb 18, 2010 6:14 pm

some of it ... it never seems to completely load. The wall 'sometimes' is run as a peak and hold VU meter @ different frequencies, and other times just patterns. It appears to be more of an 'orchestrated' event, possibly triggered by content. If that is the case, it would be pretty hard (read: impossible) to duplicate... even with scripting. Any given effect however, should be able to be duplicated to SOME degree...but not necessarily BY ME

thats why I suggested whitecap

Many thanks for the info guys; I’ll try Whitecap.

This is giving me syntax errors with the Y coord expressions.

jerohm · Post by **jerohm** » Fri Feb 19, 2010 2:48 pm

I copied and pasted the posted code into a new *.txt file without issue. I am running on a XPro PC (GF v3.93). I ASSUME you are on a Mac??? Can you give me any more on the errors detail? I used notepad and/or Vim for editting a standard *.txt file. My files are terminated with Both "\r\n". Get back if you see something.
thanks
j

does it complain about the 'Y0' def??

The OTHERS have a leading blank space OR
might need to be:
Y1="(float)(C0 > (A2 * 1 )) * A2 * 1 - A1"
OR
Y1="((float)(C0 > (A2 * 1 ))) * A2 * 1 - A1"
maybe??? ... but DOES WORK on XP/PC

If you figure it out, I will update my code post and accomodate for the situation in future posts.

also ...
Pen="1.5 - (C0 * .7)"
might be another variation ...

jerohm · Post by **jerohm** » Sat Feb 20, 2010 7:45 am

Can anybody [else] provide any insight to JayPro's syntax issues? I DID reference X15/Y15 and greater that was a v1.0 constraint, but I doubt THAT is the issue. The only other thing I can figure is SOME expression evaluator is having issues with the binary expression ( '>' ) result OR being type converted (float) and applied. As I said, this works fine on [ MY ] XPro/32; v3.93. I don't have access to a MAC, which is most likely the point of contention (... but don't even THINK that around Steve). I WOULD VERY MUCH LIKE TO UNDERSTAND WHAT THE ISSUE IS, SO ANY HELP WOULD BE GREATLY APPRECIATED. I would be MORE THAN HAPPY to provide the test code snippets to determine the nature of the limitation, but I need a willing volunteer with the Premium version and a MAC.
thanks,
j

I tried that script and didn't get any errors or warnings either. Jaypro, maybe there was a copy/paste issue?

Also, there's a new VectorC function called select() that will make like a little easier in GF 4:

// If expr is non-zero, then <a> is returned (if expr is 0, then <b> is returned).
// Example: select( { -1, 0, 2 }, { 4, 5, 6 }, { 7, 8, 9 } ) => { 4, 8, 6 }
float select( int expr, float a, float b );

jerohm · Post by **jerohm** » Wed Mar 10, 2010 9:22 pm

that is pretty much the SAME as the "?:"

this will work in the context of simple WaveShape configs expressions ... right? It is NOT fixed in some way only to vectors? Is there VectorC documentation/(more) examples anywhere? I remember seeing reference to the lib while rummaging through files, but can't recall any details... other than "use at your own risk" to be best of MY recollection

Hello All

Just got round to watching the video, could GF do this?, wouldn't it be just mind blowing if it could.

jerohm, is well on the way to re-creating the effects. I hope, (and, I know he will give it his best shot) that he succeeds.

If (when) jerohm cracks this config then I think he deserves a medal.

Go jerohm Go.
