clsk	Hello, Our next lecturer is Polkan García, from Colombia.
clsk	He has collaborated with UniNET in other opportunities, and this is way we're very thankfull to him. He's a system engineer and works an a local government entity and he also gives classes in university in the system faculty
clsk	teaching with opensource. He's also a member of the researcher group Kazak.
clsk	The tittle of his lecture is: "Modeling and Designing with GNU/Blender 3D"
clsk	You can use the channel #qc for questions and commentaries.
clsk	This presentation is available in http://changux.homelinux.org/presentaciones/blender/
clsk	Thanks to the lecturer and to all of you for being here. We hope you enjoy and learn with us.
clsk	Polkan...
clsk	[Polkan speaking now]
clsk	Good night
clsk	Before anything i want to thank this organization for giving me the opportunity of participating in this new event and naturally to all of you here.
clsk	Firstable i want to clarify that i am not a design specialist, nor anything like that.
clsk	I found blender by chance when one of my students suggested me his grade thesis en graphic computation.
clsk	and even though i'm not a graphic designer i liked it alot. and today it's my hobby.
clsk	The people that use and know blender know that it is an unique tool and through this conversation i will present you some of it qualities.
clsk	Opinions about blender.
clsk	"Blender is quickly being transformed from an impressive 3D creativity tool to a full-blown games and new media design application."
clsk	- Garrick Webster, Editor Computer Arts Magazine
clsk	To start with i want to remember you that Blender is GNU.
clsk	And what does this mean?
clsk	That it's covered by the General Public License (GPL)
clsk	That respects the four liberties:
clsk	Execute the program with any purpose. Modify to sharpen the functionality (through the source code) and redistribute copies with or without renumeration.
clsk	Distribute modified versions for the community's benefit.
clsk	Even though this is evident it is a great goal for the community, which i will talk a little more about in some minutes.
clsk	Lets talk about some history
clsk	in 1988 Ton Roosendaal co-founds the german animation studio, where he was responsible for the creation of art and the development of internal software. After some time and a large study he decides to re-make "inhouse" the toolkit.
clsk	and this is how in 1995 this development starts. Development of an application called Blender
clsk	To write blender Ton founds Not a Number (NaN) in 1998
clsk	One of the principal goals of blender from its concepture:
clsk	Make of blender a free software for proffesionl modeling and animation of 3D
clsk	Naturally embedded in the world of selling of products and parallel services to it.
clsk	This is how in 1999 a formal presentation for blender is made.
clsk	In this precise moment, NaN, had secured financial aid for 4.5 million of EUR to invest in the improvement of blender and this is how in summer of 2000 blender 2 is released
clsk	incorporating new characteristics in its 3D game engine (commercial product). At the end of 2000, there are more than 250.000 registered users and in april of 2001 Nan releases the first commercial version: Blender publisher. However, the businesses even though to what they imagened, it wen well.
clsk	i'm sorry
clsk	it didn't go well
clsk	and this is how how NaN business fails and suspends development
clsk	so then, What will happen with Blender?
clsk	In 2002 Ton Roosendaal start a new organization with no benefits: Blender Foundation.
clsk	Blender Opensouirce needs to buy rights for its own for 100.000 EUR
clsk	All this rights property of NeoGeo. So the Free Blander campaign is started
clsk	It was possible that users, developers and others could get this money and this is where the users community gives us one of the biggest lections of survival:
clsk	Softwares are written by people likle us. In only seven weeks after the cooperation of the whole world, the money is raised
clsk	and this is how on sunday <Octuber 13th in 2002> Blender is released under the GNU license.
clsk	Todays development continues in giant steps. developement continued by millions of volunteers under the leadership of its original author, Ton.
clsk	It's multi-platform: Blender exists for a variety of operating systems
clsk	http://www.blender3d.org/Download/
clsk	Easy installation
clsk	Dependence directly from the keyboard + mouse.
clsk	Those of you that already know other tools for 3D development affirmate that blender has an not much useful interface and intuitive.
clsk	However, after some practice its real power is known.
clsk	Reduced size of installer
clsk	And here the cluality that allowed me to work with Blender:
clsk	Easily extendable with Phyton
clsk	i'm sorry. Python
clsk	Blender is an application with major acceptation in Europe for being the first and only suite integrated for the creation of 3D graphics
clsk	Which allows:
clsk	To make modeling, animation, post-production, interactivity with 3D in real time
clsk	creation and reproduction of 3D games
clsk	Alright, lets see some of its architecture.
clsk	Its structure is strictly object oriented. Its 3D organized design characteristcs  in data blocks
clsk	the relationships between belocks allows it to have a complex development enviroment and a limited use of memory resources
clsk	Some of the principal blocks are: objects, Scene, Specific information for the render (camera, resolution of image) and the links to the objects
clsk	world
clsk	this block has sky, start, exposition and other enviromental variables
clsk	Object
clsk	Basic 3D information block
clsk	Contains position, rotation, size and matrices of transformation.
clsk	Mesh, Curve, Lattice, Lamp, etc.
clsk	Mesh
clsk	Curve
clsk	data like text, Bezier, BSplines, Nurbs 3D surfaces
clsk	Materials
clsk	Visual properties like colors, reflectivity and transparency
clsk	texture
clsk	Uses images, and procedural formulas or plugins to define textures
clsk	Lamp.
clsk	Uses data that are used for light, like color and shade values
clsk	Ipo (InterPolation Object)
clsk	This is the main curve animation system
clsk	It's worth to say that the Ipo blocks are used with Objects (for movement), but also with materials to animate colors.
clsk	Blender characteristics:
clsk	Modeling
clsk	Gives form to individual objects that will be used later on in the scene
clsk	Of all types of objects (Mesh, Curve, Lattice, Lamp, etc.) metaballs and vector sources
clsk	Modeled with NURBS, modeled with Poligonal.
clsk	Boolena functions of connections
clsk	Python scripting to increase functionability
clsk	Use of skeletons to create a central structure with the capacity of affecting the form and movement of the object
clsk	Deformation of the skeleton in an automatic manner
clsk	Support of Forward Kinematic animation and animation for Inverse Kinematic animation
clsk	Non-linear Mixer animation.
clsk	Syncronization of audio with the animation, reproduction, mixer and edition of it.
clsk	Python scripting to add effects.
clsk	Creation of games in 3D in real time.
clsk	raphic editor with interactive behavior without programming.
clsk	Graphic*
clsk	Advanced logic through Python
clsk	Complete support of OpenGL
clsk	No necessity of compilation
clsk	Creation of games in 3D in real time.
clsk	Rendering
clsk	Process at the end of generating the 2D image or animation starting from the created scene
clsk	Fast Renderization Engine
clsk	Previsualisation with effects of post-production, and fields and pixes box to box
clsk	Various superficials enviroment like Lambert, Phong, Blinn, Toon.
clsk	Export to extern renderers Renderman, Povray, Yafray, Virtualight.
clsk	Interface
clsk	Configurable and flexible disposition of the window for the user
clsk	Object oriented system for easy composition of complex images.
clsk	Anti-aliased sources.
clsk	text editor included
clsk	Interface
clsk	Clean and configurable
clsk	Files
clsk	all the data of an scene in a unique file
clsk	the format .blend supports gpg (gnu privacy guard) and uses of includes
clsk	imports and exports: TGA, JPG, PNG, Iris, SGI Movie, IFF, AVI and Quicktime GIF, TIFF, PSD, MOV (Windows and Mac OS X) DXF, Inventor and VRML.
clsk	Creation of executables stand-alone that contain the animation o part of a game
clsk	Enviroments with action fields
clsk	Application of architecture/industry.
clsk	Animation Photo-realistic
clsk	web design
clsk	3D graphics and animations
clsk	E-Learning
clsk	Redefining the experience of education thanks to 3D
clsk	Naturally, the best reference to everything, is found in www.blender3d.org
clsk	Many studios have used the word blender
clsk	To make their movies.
clsk	If not to animate then, to renderize, or just to design.
clsk	Shrek, Sinbad, Shrek 2, Stuart Little, Lord of the rings
clsk	Studios
clsk	Pixar, Sony Pictures, Imageworks e Industrial Light and Magic, Weta Digital.
clsk	Reference sites.
