B.A.G. Test (S68's) New PIC (better looking)

Hello all:

I used S68’s bag tool to do this (exactly what I dreamt to do when I first saw his tool, something I tried to do with Excel charts a few years ago duh :frowning: ). Thanks S68, you rule: It’s really great.

My computer is so slow it drives me nuts. I really would like to decrease the number of vertices. If you guys can look at the large version of the pic, and the code, and tell me where the catch is, I’d appreciate: eventually, I don’t want to see the moiré anymore…

The bag file I used (I parametrized some elements):


<BAG version="0.0.4">
<Reference>Cylindrical</Reference>
<Label>
Fading Wave (yeah, right)
</Label>
<F1>
u
</F1>
<F2>
2*pi*v
</F2>
<F3>
cos(u*a)*exp(-u/b)*h
</F3>
<ParU Min="0.0" Max="10.0">
300
</ParU>
<ParV Min="0.0" Max="10.0">
160
</ParV>
<UserPara Name="a" Value="1.0" Index="0">
No of hops
</UserPara>
<UserPara Name="h" Value="2.0" Index="0">
Ampliture
</UserPara>
<UserPara Name="b" Value="2.0" Index="0">
Exponential Amortization
</UserPara>
</BAG>

Because I’m at work (on lunch) :wink: , it may take me some time to get back to you (no offense).

Thanks.

Arnaud

Glad you apreciated it :wink:

If you are going for the exact surface there is not much you can do, but if you are only going for the general shape you can use much less U and V divisions and apply a SubSurf to the result, to go back to smooth

Thanks Stefano. I must say that you created a dream-tool here.

I played further with the parameter: I won’t show them off (it doesn’t reach what most think of as perfection). It’s the nature of the beast, but I really enjoy it.

NOW I KNOW WHAT I WAS DOING WRONG: V [0,1] should do it (I don’t need to spin, over again)… IN fact I will post something: I got it now…

IF you don’t have time to reply to the following questions, don’t worry.

Are the comments below correct ?

<ParU Min="0.0" Max="7.0">
60
</ParU>
<ParV Min="0.0" Max="5.0">
100
</ParV>
<!--- 
Here the script would compute 7x60x5x500 vertices

What’s the difference between the 0.4 and 0.5 version?

Thanks.

Arnaud

Here it is: if I have V do one turn only:

S68 RULES!

Arnaud

Yup,

I didn’t noticed in first post, but if

phi = 2piv

then vmin=0 vmax=1.0 is Ok, no need for higer v!

Last comment is wrong. The script will generate 60x100 vertices

I cannot remember the difference between 0.0.4 and 0.0.5 :slight_smile: Probably MACROS?

Stefano

Thanks Stefano, (aka S68).
