DIY: learning English

Earlier this week I stumbled across NPR's Goats and Soda, a blog with the byline "stories of life in a changing world." In the New Stuff section there are titles like "Help Wanted: Unlikely Geniuses To Solve Public Health Problems," "A $1 Microscope Folds From Paper With A Drop Of Glue," and "Don't Pop That Bubble Wrap! Scientists Turn Trash Into Test Tubes." All of them are about innovation and well worth reading.

But the one that really caught my attention was one about learning English: Take A New Test Aimed At The World's English-Language Learners. In an increasingly global world communication is more and more important, and English, in many cases, is becoming the default language.

Why English, you may ask. This excerpt from Wikipedia's article on world language touches on the reason why English is so widely spoken and approximates how many people speak it:
A world language is a language spoken internationally and which is learned by many people as a second language. A world language is not only characterized by the number of speakers (native or second language speakers), but also by its geographical distribution, international organizations and in diplomatic relations. In this respect, major world languages are dominated by languages of European origin. The historical reason for this is the period of expansionist European imperialism and colonialism.
The world's most widely used language is English which has over 1.8 billion users world wide...

The test NPR writes about is sponsored by Education First. You can access the test is at EF Standard English Test. It's free, can be taken over and over to assess your progress, is standardized, gives you an official score on the EF scale, and you can "post your EFSET results on your online profile as proof of your English skills to school admission officers, employers and friends." There are two types of EF tests: the quick one that take about an hour and the comprehensive one that takes about 2 hours. Both are free.

Getting started with 3D modelling: O.K. which way is up?


First of all, why get started in 3D modelling?  Answer: because you can create a lot of cool things with it: 
  • 3D games
  • Avatars for virtual worlds
  • Animated 3D avatars
  • Models of real-world objects
  • Digital artwork that changes with perspective
For reference take a look at this Wikipedia article on 3D modelling.

One way to find out if you're interested in pursuing the sometimes arduous task of working with a 3D application is to give it a try.  The folks at DAZ3D are offering free versions of some of their software:
  • Bryce 7 for 3D landscapes
  • DAZ Studio 4 for "professional 3D graphics creation" including custom figures (human and non-human) and animating the figures
  • Hexagon 2.5 for creating 3D objects (that can be used in other application) 
Hexagon is the easiest to use and most versatile for creating objects for export to other programs.  For example, you can create an object in Hexagon and send it to DAZ Studio.  You can also export an object as a Second Life sculptie.
Here's a quick look at the Hexagon interface courtesy of CGDreams at YouTube:


CG Dreams' work is so professional (and I love the English accent too).  If you're interested in seeing more about Hexagon and 3D modelling CG Dreams has its own tutorial channel.

There's a lot available about 3D modelling on YouTube -- give it a look.

That's it 'til Monday.  Have a good weekend.
