playing with the Sierpinski Gasket in houdini, coding exereise.

float resX = 600;
float resY = 600;
int numVert = 3;
float pi = 3.1415922653;
float rotOffset = pi / 6.0;
vector pos= {0,0,0};

float cx = (resX/2.0)*cos((2*pi/numVert) + rotOffset) + (resX /2);
float cy = (resY/2.0)*sin((2*pi/numVert) + rotOffset) + (resY /2);

int iter = chf(“iteration”);

for(int i=0; i<(iter+15); i++) { int num = int(((rand(i)*32767) % numVert) +1); float xVert = (resX/2) * cos((2*pi*num / numVert) + rotOffset) + (resX/2); float yVert = (resY/2) * sin((2*pi*num / numVert) + rotOffset) + (resY/2); cx += deltaD * (xVert – cx); cy += deltaD * (yVert – cy); if(i>15) {
pos.x = cx;
pos.y = cy;
}
}

## solar flare

i am workinmg on some tests for Sun project. i am trying to figure the concept for sunflares. still Artistic driven shapes, but i am planning more get more natural simulation going.

## openCL tests in Houdini

a simple sin and PI funtion exereise.

render test with indigo render

## fractal render test with Indigo Render

48Million’s Polygons below:

## NNody simulation with openCL

120.000 stars in simulated in houdini with openCL

realtime nbody on my macbook with 40.000 stars

## 1,4 billion polygomn fractal

interactive rendering in Thea render on macbook 16GB. thats the limit of my memory:

## Keyshot 3d fractal render tests

24million polygoin test

## golden ratio hexa fractals

exploring methid to create fractals in houdini and explore spline rendering in Pixars Renderman. RIS renderings of millions of spline is quite fast. Houdini also handle huge amount spline in almost realtime.

## Renderman tests

Testing renderman 21 in Houdini.

Quite fast so far

## Fractal grid tool

I am starting wrap up fractal tools and doing some test rendering.

## retro Spaceship

i am starting a new series with models of scifi vehicles

## Trangle fractals

1.4 billion polygons. 8 reflection bounces. 30 minutes rendertime on my macbook in 4k

800 Millionen polygons

## True 3d fractalsÂ

Working on system in Houdinifor handling large datasets. Simple and easy. Almost realtime feedback and efficient rendering.

## Fractal snail

Golden Ratio rendered in cycles, blender

## Fractal spheresÂ
