procedural sprial

i’ve started new project to create procedural shapes from scratch. i was playing with tan, cos and sin math, inside houdini’s VEX editor. the result: is a kind of spiral.

then i instanced it with cubes with cosine driven size, inspired by friend of mine, Gero Wortmann. also, i did some rendertest with mantra but is was really slow compare to modo. so, i’ve import everything and rendered it with modo. the rendertimes, its about a couple of seconds.

i will try to go on and pull out more complex shapes and push the result to fractal complex shapes like mandelbrot-fractals –>the picture below
the 3d fractals like the mandelbulb takes insane amount of processor power this days. i will try to keep the datasets in manageable area and fast rendertimes.

….stay tuned….

i’ve created the images below with andriod app: fractiod


houdini to modo pipline

testing different methods for houdini to modo pipeline. first try with alembic. modo have great render engine. it renders this tests in few secondes on my slow imac. (In fullHD) but modo does not support velocity in cache files.

—>i have to come up with work arounds or write same scripts / tools .

Snowtrails displacement Setup with Modo

its simple test for mud and snowtrails. i trying to recreate to old “renderman-deepopacity-displacement trick”.
instead of using a displacement shader with craps depth-information from a light. i rendering sperate passes and use nuke with timeecho node and expressions to create a animated displacement maps for the trails.

i am trying to create with python a one-renderpass workflow like with the smart rendermanshader setup in maya

the displacment map out of nuke
