Blender Depth of Field Animation

Nikolaus Gradwohl2012-01-12T06:11:23+01:00

Today I made a video that animates the depth of field. The particles are generated using an array modifier and a displace modifier.

The dof effekt was rendered by animating the distance value of the camera between 2 and 40 and by adding a defocus-node in the node editor. fStop was set to 8 all other values are the default

caustics with blender and cycles

Nikolaus Gradwohl2012-01-10T05:41:14+01:00

When I modeled some glass metaballs yesterday I found out that the blender-internal renderer doesn't support caustics (the light reflections on the ground, when light falls throug a sphere of glass for example).But after some googeling I noticed that this is the perferct oportunity to give the new blender renderer named cycles a try - because cycles renders them. After some experimenting with various lightsources I finally used two small planes with an light emmiting material.

It also took me a while to generate a material in the node editor that displays a gradient on the backgound, because relies on the node editor much stronger than the blender interal renderer and I haven't used material nodes so far.

Unfortunately my graphics card is too old for blender to use the GPU for rendering - so it took a while to render on my box

another compositing test with blender

Nikolaus Gradwohl2012-01-09T06:16:24+01:00

This is another compositing test I made with blender. This time I modeled the Cup as a mate object that doesn't get rendered but does hide parts of the little man who is swimming in my coffee and casts shadows on the table. This is also my first blender scene where I separated objects on differend render scenes to hide It from the final compositing.

as usual you can download the blend file here

alienhead in blender

Nikolaus Gradwohl2012-01-07T18:18:01+01:00

This weekend I tried to work on my modeling skills. I tried to model the alien-head to be animated so I think you will see it again soon :-)

you can download the alien-head here

hair particle system

Nikolaus Gradwohl2012-01-06T09:42:56+01:00

And here is one more hairy ball rendered with blender. I tried to make it a bit anemone like by removing the gravity and adding a litte self turbulence to the particles, I also modified the strand rendering and added a blend texture to make the hair grow smaller towards the top and make it look more like an anemone

dissolving sphere in blender

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

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+01:00

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+01:00

After watching the awsome "flame-thrower"-tutorial from 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+01:00

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+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
