Also it works fast enough for interactive parameter tweaking. Thanks Syntopia!! Title: Re: Brute RotJulia Post by: matsoljare on October 01, 2012, 08:03:22 PM Wow, that's absolutely amazing! More of this formula, please! O0
Title: Re: Brute RotJulia Post by: Kali on October 02, 2012, 01:08:55 AM Wow, that's absolutely amazing! More of this formula, please! O0 Thanks... I'll try to explain: At every iteration, I take x and y coordinates as real and imaginary parts of a complex number, the same you do in 2D. I square the number as in a standard Julia, but then I apply a 3D rotation before adding julia constants. That's it. In the last version I'm testing, the julia constants are also rotated, and I added a scaling factor that helps into finding interesting shapes. |
