blender fluid simulation test

Nikolaus Gradwohl2011-12-30T06:50:54+01:00

Today I tested the blender fluid simulation system. Very cool stuff but if you have no idea what the parameters mean (like me for example) - it's very easy to render something that takes the whole night to bake and looks very unimpressive. This reminds me a bit on rendering fractals on the atari ST :-)

however here is the download link to the blend file

Walking-Cycle animation with blender

Nikolaus Gradwohl2011-12-29T08:35:56+01:00

today I modelled and rigged a very simple figure with blender and made an animation of a walking cycle.

faaaaaaar from perfect - but hey! It walks! ( read: guru is very proud!)

as usual here is the blend file to download if you want to play with it

playing with blender composite nodes

Nikolaus Gradwohl2011-12-28T06:23:15+01:00

Today I learned what the blender node-editor is here for and how to use it. I made a simple scene containing 2 cubes, a camera and a lamp and composed the scene on an photo I made a while ago.

the composite editor also alows to filter the composed images, adjust color values, etc ...

but in this sample image I just added the two images based on the alpha values of the 3D scene.

very powerfull tool - and I certainly only have scratched the surface yet

I also uploaded the blend file again, which can be downloaded here

Blender Test-Animation

Nikolaus Gradwohl2011-12-27T06:57:25+01:00

The next tool I want to brush up my skills a bit is blender. I already have some modeling experience in blender because of my 3D printer, but I haven't made many animations yet.

So here is a first testrender of a moving and rotating cube to verify the brand new blender 2.61 is working on my box.

I only used some keyframes on translation and rotation for the camera and the cube object. Nothing very fancy yet but if you like you can download the blend file here

This is a short animation I made with blender 2.5 to test shape key animation

Vulcano 3D model

Nikolaus Gradwohl2011-05-18T05:37:18+02:00

I wanted to play a bit with the new Blender 2.5 and made a model of a vulcano. I haven't found the time yet to print it on my makerbot - so I consider it as work in progress.

you can download the blender file here or the stl version here

3D-Printed Wizzard

wizzard

While browsing through thingiverse I noticed a huge number of draggons but a serious lack of wizzards. So I started the new blender 2.5 and moddled one.

The blender 2.5 GUI is a really huge improvement over the 2.4-Versions - absolutely thumbs up for this :-)

you can download the blend file or you can download the stl file if you want to print it yourself.

Then I tried to print something using the support material option of skeinforge for the first time. The support-material can be activated in the "Raft" Section of the skeinforge settings. Make sure you set "Support Inset over Perimeter Extrusion With (ratio)" to some negative value - I used -3 - or else your support material will stick to your model.

Generating 3D Objects from Heightfields

Nikolaus Gradwohl2010-03-28T08:39:00+02:00

Back in the old days, when I was a basic hacking teenager, the state of the art technique for getting awsome 3D Graphics on the atari-screen was rendering triangles based on a grayscale bitmap - aka heightfield.

I reanimated this knowledge to generate a 3D object from such a heightfield. so in fact this blog article shows how to take something like this

heightfield

and turn it into something like this.

using the BlenderGameEngine as OSC client

Nikolaus Gradwohl2009-03-08T15:18:00+01:00

i just managed to use the GameEngine of blender as a client for OSC events :-)

now i can change the color of a cube by sending osc events from my pd-patch or the ruby-script i wrote for my openframeworks-demo

bge-cube.png

the blend file can be downloaded here

the blend file needs OSC.py by Daniel W. Holth to be in the python searchpath, so either copy it to location you start blender form or copy it to your site-package folder (obviously i'm not the only one who had the idea of using this lib with the blender game engine :-] )
