Dice

In this exercise we used vertices to draw a dice. After modelling the vertices we over-layed a texture, we drawed before in Photoshop.

The result can be seen in the applet beyond. Use UP and DOWN to zoom in or out and drag the dice to rotate with your mouse!

Applet demonstration here.

3D Modelling

In this exercise I imported a 3D model. I found a nice modell of a watering can on oyonale.com. To load OBJ into processing, an OBJ loader like the SAITO OBJ loader is needed.  The code is quite simple an can be seen here on my page.

You can rotate the object by dragging it with your mouse. Try it out here.

Video recorder

For this simple video recorder, I took the animation from a previous exercise (confetti) and added a record an replay function. The programm makes a mov-File of the animation. The record starts by pressing ‘R’ and stops after pressing ‘S’. After recording the file can be played/paused by pressing ‘P’.

Since the execution doesn’t work within the browser you can download the source code (pde-file) here.

Brightness tracking

The program two functions. Either recognize the brightest point in the webcam image or following a indivual definable color. This can easily be done by clicking somewhere inside the image. Then every pixel gets compared with the choosen color. If there’s a similarity, the pixel is going to be considered as a part of the object.

By pressing UP or DOWN the tolerance value changes. Pressing the right mouse button resets the picked color and the brightest point is overlayed (yellow circle).

Try it out! You can view the source file to compile (unfortunately it does not work within the browser).

Confetti

This applet generates random circles with random colors and their opacity (alpha) is determined by the vertical mouse position.

The applet can be viewed here. Move your mouse cursor up and down and watch what happens!

Digital pipette

This application is and does nothing more, what a conventional color picker does: It gets the exact color of the pixel on which it is clicked on. The upper right color box is the acutal clicked pixel color, the second one is the color of the previous pixel.

Try it out here, by clicking into the picture.

Color wheel

This displays all colors with their respective complementary color.

You can view the wheel in this applet.

Pop-Art

The typical Andy Warhol picture effect. One color is generated randomly and the second one is the respective complementary color.

The applet can be tried out here.

In our case, we altered digital photos and learned mor about how to manipulate pixels and techniques to overlay several images.

Image manipulation

I created several pixel manipulations with Processing.

You can see the result in this applet.

Pixel Image

The tasks was about creating a “pixeling” effect. This can be achieved by several ways. I created a grid and took the very first point of each box. Then I filled the rest of the box with the first pixel’s color.

The pixel-resolution can be adjusted whithin the applet by pressing UP and DOWN.

Threshold

In order to get a pure black-and-white picture, you need to set a threshold. The threshold value determines, where the border between black and white is.

You can try it on your own with my applet. Press UP or DOWN to increase or decreasae the resolution and LEFT or RIGHT to change the threshold.

Overlay Images

This applet shows how to overlay two different images. The source are two pictures with the same size. You get different results by adding, subtracting or multiplying.

Check out the applet here.

The ZFS project has been discontinued. The mailing list and repository will also be removed shortly.

Originally ZFS has been designed and developed by Sun Microsystems. ZFS is was a file system and logical volume manager with great abilities. It supported high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z and native NFSv4 ACLs. As usual of Sun, ZFS is implemented as Open Source.

So much for that. Now back to Apple’s kickout.

ZFS has been ported to Mac OS X and was released as an open source project on Apple’s Mac OS Forge collaboration site in 2007.  Many rumours were afloat that ZFS becomes the default file system for Mac OS X Leopard, but it appeared only with limited read-only capabilities.

The inclusion of the technology in its early product pages for Snow Leopard Server indicated Apple’s interest in ZFS. But the Apple removed the information on their site and the support for ZFS was not included in either Snow Leopard or Snow Leopard Server.

And the news about the cessation of Apple’s ZFS support, suggests that they have given up the hope of achieving licencing terms for the technology.

Macrumors reports, that Apple yesterday posted a new job listing for a file system engineer, which indicates that the company may be expanding its in-house team to improve or develop its own file system technologies.

Here’s a small cutout of my revised storyboard (click on thumbnails to enlarge them):

Image merge

First composing task was about merging/composing three different pictures into one. With the transformation tool, and gaussian blur filter you can achieve a picture like this:

Aurora borealis

The following picture has been realized with Adobe Illustrator. The great step-by-step tutorial on how to create a “Mac OS X (Snow) Leopard”-like Aurora borealis effect: http://vector.tutsplus.com/illustration/make-an-aurora-borealis-design-in-illustrator

To download the wallpaper (1680 x 1050 pixel) do a right-click on the preview and choose ‘Save target as …’.

I don’t know yet, how (technicial realisation) to realize it. But further details will be posted on this blog. Check back soon!
