Hi all,
MathMod3.1(Win64/WIN32) is available for download from:
https://sourceforge.net/projects/mathmod/
Changelog for MathMod3.1 (11/03/2015)
1) Add Perlin/Worley Noise (NoiseP and NoiseW) functions support for parametric surfaces:
(see "FresnelNoise", "BreatherNoise" and "TorusNoise" examples)
2) Bug fixes _________________ Cheers,

hello
a message error to iso
noise duplin
error at position 0
( very nice prog a little time is well to shut down the runtime with k3D)
ps
Have you need of my iso formula of icosaedron because i post and nothing else read !,
may i post a new tread for that ?
cheers

Hi,
Code:  a message error to iso
noise duplin 
You`re right, to correct this message error, just cut from the script:
Or replate it with :
You can also start playing with the Noise functions and replace it with something like:
Code:  "Noise": "2*NoiseW(2*x,2*y,2*z,1,2,0)", 
Code:  ( very nice prog a little time is well to shut down the runtime with k3D) 
Did you mean MathMod makes your system crash? it happens occasionnaly for me when playing at very height resolution. This is most probably du to my old graphics card that can't handle big amount of graphics data.
Code:  Have you need of my iso formula of icosaedron because i post and nothing else read !,
may i post a new tread for that ? 
Of course you can create a new thread and all users experience sharing is appreciated _________________ Cheers,

hello nextstep
i was a little tired , i would just say that,
it takes some time to get rid of habits with K3D and appreciate more mathmod .
and also the new fonctions .
In the future , a save to anim in avi format will be possible?
cheers

If K3DSurf suits your needs, it's good to continue using it... In my case, I switched to MathMod because I needed a more powerul tool that can support new advanced features.

I did it for K3DSurf but it was too buggy...how about using a third party program to catch screenshots and animations directly from the display screen?
I used CamStudio to make this demo _________________ Cheers,

hello nexsteps
your convert K3Dsurf don't work for me.
For all of my tryout i am a x.js empty

i am a meesage error?

Hi denisc,
From what you said, it looks like you have problems when converting your old .k3ds files to the new MathMod's file format .js , right?
I took your two examples and saved them in a test.k3ds file :
Code: 
Name: Schwartz
/*
Author: Schwartz ...
*/
F(): cos(x) + cos(y) + cos(z)
[x]: 4 , 4
[y]: 4 , 4
[z]: 4 , 4
;
X():u
Y():sin(pi*((u)^2+(v)^2))/2
Z():v
[u]:1, 1
[v]:1, 1
;

After conversion with MathMod, I got a test.js file in the same directory as the original test.k3ds:
Code: 
{
"MathModels": [{
"Iso3D": {
"Description ": ["Author: Schwartz ..."],
"Name": ["Schwartz"],
"Component": ["Schwartz"],
"Fxyz": ["cos(x) + cos(y) + cos(z)"],
"Cnd": [""],
"Xmin": ["4 "],
"Xmax": [" 4"],
"Ymin": ["4 "],
"Ymax": [" 4"],
"Zmin": ["4 "],
"Zmax": [" 4"]
}
},
{
"Param3D": {
"Description ": [""],
"Name": ["_2"],
"Component": ["_2"],
"Fx": ["u"],
"Fy": ["sin(pi*((u)^2+(v)^2))/2"],
"Fz": ["v"],
"Cnd": [""],
"Umin": ["1"],
"Umax": [" 1"],
"Vmin": ["1"],
"Vmax": [" 1"]
}
}]
}

I don't know where the is problem...can you give more details?
You can write in French or Spanish if you want. _________________ Cheers,

hello next steps
thanks for your comment
i retry the js convert.
That work with iso formula , but not for parametric formula when you load json
script.
because you are just : { "MathModels": [ ]} write in the json script
(In the json scipt with iso, you are the good formula in
{
"MathModels": [{
"Iso3D": {
"Description ": ["Author: Schwartz ..."],
"Name": ["Schwartz"],
"Component": ["Schwartz"],
"Fxyz": ["cos(x) + cos(y) + cos(z)"],
"Cnd": [""],
"Xmin": ["4 "],
"Xmax": [" 4"],
"Ymin": ["4 "],
"Ymax": [" 4"],
"Zmin": ["4 "],
"Zmax": [" 4"]
}
and para
{ "MathModels": [ ]}
try to convert and reopen your examples in 2 separate json .
one for iso, second for parametric .
cheers
cheers
ps
i am one parametric json correctly write?
But i am a message error when i try to reopen
illegal number at position 17
the difference with other are just values.
x
ex
1/ X = sin(u)
Y= sin(u)
Z= sin(u)
not work
{ "MathModels": [ ]}
2/ X = 3*sin(u)
Y= 3*sin(u)
XZ= 3*sin(u)
work with mesage error when reopen
(all parametric formulas work in k3dsurf)
one exemple
X():1*cos(u)*(1+1*cos(1/5*u))
Y():1*sin(u)*(1+1*cos(1/5*u))
Z():0
[u]:5*pi, 5*pi
[v]:,
my formula saved in
CONCHOÏDE DE ROSACE15 .k3ds
my CONCHOÏDE DE ROSACE15 .js
{ "MathModels": [ ]}
all my parametric formula(not exemples)
had not tiles( *)

Hi,
Code: 
Name: Schwartz
/*
Author: Schwartz ...
*/
F(): cos(x) + cos(y) + cos(z)
[x]: 4 , 4
[y]: 4 , 4
[z]: 4 , 4
;
X():1*cos(u)*(1+1*cos(1/5*u))
Y():1*sin(u)*(1+1*cos(1/5*u))
Z():0
[u]:5*pi, 5*pi
[v]:,
;

After conversion, we have:
Code: 
{
"MathModels": [{
"Iso3D": {
"Description ": ["Author: Schwartz ..."],
"Name": ["Schwartz"],
"Component": ["Schwartz"],
"Fxyz": ["cos(x) + cos(y) + cos(z)"],
"Cnd": [""],
"Xmin": ["4 "],
"Xmax": [" 4"],
"Ymin": ["4 "],
"Ymax": [" 4"],
"Zmin": ["4 "],
"Zmax": [" 4"]
}
},
{
"Param3D": {
"Description ": [""],
"Name": ["_2"],
"Component": ["_2"],
"Fx": ["1*cos(u)*(1+1*cos(1/5*u))"],
"Fy": ["1*sin(u)*(1+1*cos(1/5*u))"],
"Fz": ["0"],
"Cnd": [""],
"Umin": ["5*pi"],
"Umax": [" 5*pi"],
"Vmin": [""],
"Vmax": [""]
}
}]
}

The problem comes from:
Code: 
"Vmin": [""],
"Vmax": [""]

Blank values are not accepted by MathMod, because MathMod doesn't support curves definitions (yet) _________________ Cheers,

hello
it's not the solution
i change my formula and save with k3dsurf
X():1*cos(u)*(1+1*cos(1/5*u))
Y():1*sin(u)*(1+1*cos(1/5*u))
Z():0
[u]:5*pi, 5*pi
[v]:0, 0
and when i convert with mathmod 3.1
{ "MathModels": [ ]}
i am not
{
"Param3D": {
"Description ": [""],
"Name": ["_2"],
"Component": ["_2"],
"Fx": ["1*cos(u)*(1+1*cos(1/5*u))"],
"Fy": ["1*sin(u)*(1+1*cos(1/5*u))"],
"Fz": ["0"],
"Cnd": [""],
"Umin": ["5*pi"],
"Umax": [" 5*pi"],
"Vmin": ["0"],
"Vmax": ["0"]
}
}]
}
why you not test all with k3dsurf in first position?

Hi,
Code:

What do you think I'm doing right now?
Code: 
and when i convert with mathmod 3.1
{ "MathModels": [ ]}
i am not

can you try convert this in the first place and see what you got ?
Code: 
Name: Schwartz
/*
Author: Schwartz ...
*/
F(): cos(x) + cos(y) + cos(z)
[x]: 4 , 4
[y]: 4 , 4
[z]: 4 , 4
;
X():1*cos(u)*(1+1*cos(1/5*u))
Y():1*sin(u)*(1+1*cos(1/5*u))
Z():0
[u]:5*pi, 5*pi
[v]:,
;

It's useless to continue this discussion if you don't help yourself a bit in finding the root of the problem... _________________ Cheers,

i not understand what you say?
I am no probleme in special way?
if you write your k3dsurf (.k3ds) , first with a wordpad or editor of text and
save with . with K3ds prog first ;in final , it's not the same result .??
i not understand what , but it is the result is very different???!!

hy
another exemple
i try with your formula of torus
In K3ds v0.6.2
you can do
edit and after save as , i save as y.k3ds (you must make the( ).k3ds )
X()1+ 0.5*cos(u))*cos(v)
Y():0.5*sin(u)
Z()1+ 0.5*cos(u))*sin(v)
[u]:0, 2*pi
[v]:0, 2*pi
i try to convert with mathmod 3.1
when i open my y.js
you can see { "MathModels": [ ]} for result
if i try all your exemples in iso formula , that work find.
i not understand, where is the probleme fondamental in all?
i am on w7 pro, not 64 bit.
I will test on W8 64?
(perhaps a little bug when K3D write the text)
' i not understand how you have
{
"Param3D": {
"Description ": [""],
"Name": ["_2"],
"Component": ["_2"],
"Fx": ["1*cos(u)*(1+1*cos(1/5*u))"],
"Fy": ["1*sin(u)*(1+1*cos(1/5*u))"],
"Fz": ["0"],
"Cnd": [""],
"Umin": ["5*pi"],
"Umax": [" 5*pi"],
"Vmin": [""],
"Vmax": [""]
}
for me , i am a empty .js
just
{ "MathModels": [ ]}
in fact the .k3ds had not be converted?)

i try with windows 8 64bit and mahmod 3.1 64 bits with K3dsurfV0.6.2
with klein
i am the same result
the file.js was not converted.?
just { "MathModels": [ ]} write on
perhaps on my last posts i was a little confused (sorry for that)
but it's a true probleme?
CA serait bien , si d'autres personnes pouvaient confirmer , ca etait fait sur 2 ordi differents.
that would be nice if others could confirm, i used 2 differents computers.

Hi denisc,
I think it's not working for you because you didn't add ";" at the end of the parametric description. Try to convert this, it should work:
Code: 
X():(1+ 0.5*cos(u))*cos(v)
Y():0.5*sin(u)
Z():(1+ 0.5*cos(u))*sin(v)
[u]:0, 2*pi
[v]:0, 2*pi
;

Je pense que la conversion des fichiers .k3ds ne marche pas pour toi car il manque le séparateur ";" a la fin de la définition paramétrique de ton model.
Essayes de sauvegarder le code en haut dans un fichier .k3ds et converties le en .js...ça devrait marcher _________________ Cheers,
Abderrahman
