hello all Smile

thanks taha Smile

Just a cube.


Code:


0.4*
((x+3.5)*(x-3.5)-(-.4*(0*(cos(x*2) + cos(y*2) + cos(z*2)) + 12*(cos(x*2)*cos(y*2)*cos(z*2))))+(x+3.3)*(x-3.3))*

((y+3.5)*(y-3.5)-(-.4*(0*(cos(x*2) + cos(y*2) + cos(z*2)) + 12*(cos(x*2)*sin(x*2)*sin(z*2)*cos(y*2)*cos(z*2))))+(y+3.3)*(y-3.3))*

((z+3.5)*(z-3.5)-(-.4*(0*(cos(x*2) + cos(y*2) + cos(z*2)) * 12*(cos(x*2)*cos(y*2)*cos(z*2))))+(z+3.3)*(z-3.3))+3



The idea is to make the cube sides differ Wink

Hello all, hi Torolf ,

Allow me Torolf to join you in some your interests Razz

Just a cube:


Code:
(x/(0.2+ (1-abs(cos(3*pi*z) + cos(3*pi*y))/8 )))^100 +( y/(0.2+ (1-abs(cos(3*pi*x) + cos(3*pi*z))/8 )))^100 +( z/(0.2+ (1-abs(cos(3*pi*x) + cos(3*pi*y))/8 )))^100 -1

[x]: -1.2 , 1.2
[y]: -1.2 , 1.2
[z]: -1.2 , 1.2

I stumbled across this software about a year ago. But the limitation for algebraic surfaces only ultimately let me to throw it away. However on this page http://imaginary-exhibition.com/galerie.php#t1 I found http://virtualmathmuseum.org/mathart/MathematicalArt.html Be sure to check all of them. Paul Nylander is the best one ever Wink
