I could made this part fit into a single paragraph. Serious, just watch:
Light, textures and shaders are part of the rendering state, so they are handled
just as shown in the previous post.
Sure, using them requires the use of subclasses of

but the idea is the same. So, just spend some time with the Open Scene Graph
reference documentation and you are done.
In the previous part, we talked about two very important OSG concepts: nodes and
drawables. Now, we’ll deal with a third very important concept: state sets.
These form what I consider the triad of the very fundamental OSG concepts.
Having conceived this text as a practical guide, I was tempted to jump right
into action, with an exciting example program displaying some nifty 3D graphics.
But, also having conceived this text as something useful for “very beginners”, I
resisted this temptation and decided to start with some basic concepts without
which the Open Scene Graph (OSG) would not make sense. So, before talking about
OSG per se, I’ll start spending a little time with a quite fundamental
This is the prologue for a series of posts teaching the most important concepts
for anyone learning to use the Open Scene Graph

Esse foi um minicurso que eu ministrei na Game Development School (GDS) da Unisinos, em novembro de 02007. Estão disponíveis os slides e o código fonte usado nos exemplos.
Eu sou daqueles que ainda não conseguiram entender o que existe de tão espetacular no tal XML.

Undergrad Class Assignments These are some class assignments I did when I was an undergraduate Computer Science student. If nobody find them useful, they’ll at least help me to remember some of the assignments I enjoyed most.
The majority of the stuff here (specially the older ones) are in Portuguese.

VOX is a speech recognition school project I worked in back in 1998. Here’s a
brief description of the project, and most of the artifacts we produced back
