Hi all,
I wish there is still fervency to the valentine's day there are more hearts and more enjoy
Yes with some exceptions we can do a lot, you're seeing the section of the tiny rods dwon, there is no sameness over all the heart surface but anyway it remains reasonable :
For the general case I write:
Code: | F(x,y,z)= heart^2 + mesh(x,y,z)^2 - R^2 , so that
heart = sqrt((sqrt(x^2+(abs(y)+0.5)^2)-1.5*acos(cos(atan2((abs(y)+0.5),x))^23 ) )^2+4*(z/(0.05*x+1))^2 )-4
or
heart = (sqrt((sqrt(x^2+y^2)-acos(cos(atan2(y,x))^5 ) )^2+8*z^2 )-4 )/sqrt(2)
and "mesh" is a choosen function as you want. |
For exemple:
Code: | F(): ( (sqrt((sqrt(x^2+y^2)-acos(cos(atan2(y,x))^5 ) )^2+8*z^2 )-4 )/sqrt(2) )^2 +(cos(4*x)+cos(4*y)+cos(4*z))^2/16-0.0225
[x]: -8.5 , 6
[y]: -6 , 6
[z]: -1.5 , 1.5
|
Code: | F(): ( (sqrt((sqrt(x^2+y^2)-acos(cos(atan2(y,x))^5 ) )^2+8*z^2 )-4 )/sqrt(2) )^2 +(cos(4*x)+0.3*cos(12*x)+cos(4*y)+0.3*cos(12*y)+cos(4*z)+0.3*cos(12*z))^2/16-0.0225
[x]: -8.5 , 6
[y]: -6 , 6
[z]: -1.5 , 1.5 |

This pattern is soooo cuuuuute I couldn't resist to put it in my raytracer.
Code: |
F(x,y,z,t)=atan((cos(32*x))^3+(cos(sqrt(3)*16*y+16*x))^3+(cos(sqrt(3)*16*y-16*x))^3)+0.6+800*z^2=0
x [ -0.5, 0.5]
y [ -0.5, 0.5]
z [ -0.2, 0.2]

Hello all,
Oh yes Furan it's really so cute pattern very sorry I'm a little bit late
Code: | ( atan((cos(8*x))^3+(cos(sqrt(3)*4*y+4*x))^3+
(cos(sqrt(3)*4*y-4*x))^3)+0.8 )^2/4
+
2*( (sqrt((sqrt(x^2+y^2)-acos(cos(atan2(y,x))^5 ) )^2+8*z^2 )-4 )/sqrt(2) )^2-0.0225
x]: -8 , 6
[y]: -6 , 6
[z]: -1.6 , 1.6 |
