dissolving sphere in blender

Nikolaus Gradwohl2012-01-05T06:27:29+00:00

This is a test scene I have made to try the explode modifier from blender The explode modifier uses a particle system to define where the vertices are removed and where they should fly to. The particles themselve are not rendered in this scene

you can download the blend file here if you want to see how its made.

Camera Tracking in Blender 2.61

Nikolaus Gradwohl2012-01-04T09:20:01+00:00

today I played a bit with the new camera-tracking features in blender 2.61

I recorded a short video of my desk and added my dragon model from yesterday to the scene. I messed up the shadow a bit and the compositing would require a looot more love but its really impressive how easy the tracking can be (once you have figured out what todo, which was the harder part :-))

fire breathing dragon in blender

Nikolaus Gradwohl2012-01-03T06:19:20+00:00

After watching the awsome "flame-thrower"-tutorial from blenderguru.com I wanted to give the particle and smoke system a try. I modelled a very simple animation of a dragon instead of a flamethrower and I haven't added any fancy materials or compositing stuff yet. But I think the fire-effect is still very impressive

you can download my blender file here - but be warned - it takes a while to render.

here is a still form the animation, in case you can't watch the video


animating a growing vine in Blender 2.6

Nikolaus Gradwohl2012-01-02T05:58:10+00:00

There are some really nice video-tutorials out there in the internets that show who to animate a growing vine in blender - unfortunately all I found are for blender 2.48 and use keyboard shortcuts that aren't working in blender 2.5/2.6 anymore.

so I tried to recreate them for the current blender-version. Here is a short video to show what the final animation looks like.

blender fluid simulation test

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

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+00:00

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+00:00

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+00:00

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

3D mushrooms in processing

Nikolaus Gradwohl2011-11-16T06:06:17+00:00

My mushroom-drawing from yesterday inspired me to do some 3D coding in processing again so I made a rotating 3D version of my purple mushrooms

hiding some screws on my Chair

Nikolaus Gradwohl2011-11-12T11:48:29+00:00

I got a new chair from ikea which came with armrests. I didn't want to screw them on the chair, because I generally don't like arm-rests on my chairs and they don't fit under my desk. Not mounting the arm-rests left some blank nuts which didn't look very pretty.

3D-printer to the rescue - I printed some caps to hide the nuts

You can download the scad file or the stl file If you need an example or happen to have the same chair
