Happy new year!

A year is fading, not before bringing us a lot of wonders, a lot of fantasy and art in the hands of countless magicians around the world. Everyday I feel grateful of being part of the amazing people that makes imagination meet reality.

-What do you do? …once in a while a friend ask, and all I can answer is: -where dreams come true!

The great Pixologic team is wishing you all the best for this new year and much more great things awaits for us all.

Thank you everybody.

Happy new year!

Adobe Industry Certifications

As part of my continuous learning process I have decided to take several industry certifications from Adobe here in the U.S. The knowledge is the only thing that nobody can take from you 🙂

Adobe Certified Visual Design Specialist (Photoshop, Illustrator, Indesign), Visual Communication (Photoshop), Print and Digital Media Publication (Indesign),  and Graphic Design and Illustration (Illustrator).

Installing an older version of OS X


May be you find yourself in a situation where you need to install an older version of OS X, to test a software or to provide support for older versions since not everyone need to move at the speed

that OS releases cycles dictates. In Apple case that’s a problem as they don’t make it easy. Here’s some tips that could help you to do that. Shortly after a new version is released they make it impossible to just run the older installer within a more recent version.

With OS X El Capitan, Yosemite, or Mavericks, you can use a USB flash drive or other removable media as a startup disk from which to install OS X.

1-Using the Disk Utility create the partition where you will install the older version


2-Make sure you have an installer of the old version you need, either from a backup, a disk, an image, etc

3-Mount your USB flash drive or other volume. You could also use a secondary internal partition.

4-Open the Terminal app, which is in the Utilities folder of your Applications folder.

5-Use the createinstallmedia command in Terminal to create the bootable installer.  For detailed usage instructions, make sure that the appropriate Install OS X app is in your Applications folder, then enter one of the following paths in Terminal:

The following examples assume that the OS X installer is in your Applications folder and the name of your USB flash drive or other volume is MyUSB:

Example for El Capitan:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/
createinstallmedia --volume /Volumes/MyUSB--applicationpath 
/Applications/Install\ OS\ X\ El\ Capitan.app

Example for Yosemite:

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/
createinstallmedia --volume /Volumes/MyUSB--applicationpath 
/Applications/Install\ OS\ X\ Yosemite.app

Example for Mavericks:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/
createinstallmedia --volume /Volumes/MyUSB--applicationpath 
/Applications/Install\ OS\ X\ Mavericks.app

Then restart, press the alt key during boot to select the USB source and start the installation. If you encounter this error along the process This copy of the Install OS X Yosemite application can’t be verified. It may have been corrupted or tampered with during downloading or similar usually is because the system is detecting a more recent date than the valid range for “installing” those versions, in that case you need to follow a few more steps to trick the system date into a valid one:

While at the “Install OS X” boot menu. Pull down the “Utilities” menu option and choose “Terminal” . The manual date format to use is a little weird, it looks something like mmddHHMMccyy.

In simpler terms, that is: Month Date Hour Minute Year, and it’s entered as a solid line with no breaks or spaces between the numbers. Previously go online and research the release date and the valid range of the OS you want to install and then type any date in that range. Disconnect from the internet to perform this step and type on the terminal such a date, for example for Yosemite I’ve used date 120082315 , and then you will be able to proceed with the installation, reconnect to internet and get the correct date back.

Stroking improvements

To accurately shape a stroke in QuadPaint, the user can create new pinned vertices with double click, in the future more powerful curve controls will be implemented.  Today I’ve improved the implementation by allowing the deformation to be independent from stroke density. (unlike previous algorithm) and I’ve solved a bug that prevented to simultaniously deform linked strokes.



Stroking improvements

QuadPaint control keys



This is the current main hot keys and actions to control the strokes of QuadPaint, and by changing the boundary you can control the inner quadrangulation.

Right click a vertex allows to smooth and move the stroke.

Hovering a vertex and pressing DEL , remove the vertices.

Double Click a vertex, will pin it so you basically created a new edge freely to move.

Double Click a segment, between 2 vertices will insert a new point, provided that the radius is smaller than the segment, otherwise will capture the closest vertex an pin it.

Ctrl + Click a vertex will split the stroke into 2 strokes.

Pressing +(plus) over a stroke will increase vertices count by 2. (some manual smoothing will be required to make vertices more even, will improve soon)

Pressing – (minus) will decrease by 2

Overlapping 2 vertices will merge them on mouse release.

Overlapping segments will be intersected on mouse up.

The numerical hint tells the number of vertices between 2 pinned points (inclusive), updated at mouse up.

Moving a vertices very far, after release will insert new divisions, moving them too close will merge them to maintain an average distance.

Sometimes the preview snap to surface incorrectly, but the final result will be much better because more smoothing and post process is used at execution time.


PS: seems I had some ghosts at my side because the room was completely silent and I got those eerie sounds Bouhahahaha
