A Houdini 9 new feature is Soho, a python API for include new render engines to Houdini. See “$HH/soho/soho.doc” for a complete introduction from SideFX.

I want to finish my little toy, a render engine from scratch, Primate©.

The image of this post was rendered in Primate©, original size 1800×1600, render time about four minutes, not bad for early tests.

In this post I show several tests of the Julia set fractals, I have used own color methods.

Julia Set 0×001x001

 

 

Julia Set 0×001x002

 

Julia Set 0×001x003

 

Julia Set 0×001x004

 

These fractals have been rendered using the GPU of my graphical card, a Quadro FX. Using the GPU, we can parallel the calculation of this beautiful monster.

Making your own solver in Houdini has several advantages, mainly you can optimize it for extreme effects, where generalist RBD Solver fail.

For example, you can make a solver that ignores torque, rotations and other calculations not important for your simulation. In this way, you can add more RDB Objects.

At this moment, I am working on Pocoyo, a pre-school animated series about a young boy who dresses in blue and who is full of curiosity. It is made by Zinkia Entertainment, and distributed by Granada International. There are 52 episodes in series 1 and each is 6 minutes long. The British actor and comedian Stephen Fry narrates the English language version which is shown in the U.K. on CITV.

• Pocoyo: Pocoyo is the main character of the series and the programmes centre around his adventures. He is a young boy who is full of curiosity and who loves to play games. He wears blue clothes and wears a big blue hat.

• Pato: Pato is a yellow duck who wears a small green hat. He is also a good friend of Pocoyo. Pato means duck in Spanish.

• Elly: A pink elephant who wears a blue back-pack; she is Pocoyo’s best friend. She usually rides around on her scooter.

• Loula: Pocoyo’s yellow spotty pet puppy and companion. She adores Pocoyo.

• Sleepy Bird: A teal-coloured bird who sleeps a lot. She only wakes up to turn off her alarm clock and to do other things, like flying, although she usually flies with her eyes closed.

The particles simulation has been created with Houdini.

Shake for compositing.

The implementation used to create that animation use the Lattice-Boltzmann Method, which is a kind of cellular automaton to simulate the macroscopic behavior of fluids. The animation only show force field vectors, not surface reconstruction.
