Open Scene Graph: The Basics

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 question.

The World's Most Dangerous Professions

Barack Obama is the 44th president of the USA. In the history of that country, four presidents have been murdered. This means that almost 9.1% of the USA presidents have been killed during their terms. Another 11 presidents died of natural causes during their terms. This sums up to an impressive number: more than 1⁄3 of the presidents of the USA died while presidents of the USA. Therefore, one can easily conclude that president of the USA is one of the most dangerous jobs of the world!

Cadeiras caras no TRE de São Paulo

O Jornal da Band de ontem denunciou que, no TRE de São Paulo, “os magistrados compraram cadeiras que custam 12.796 reais [mais de três anos do salário mínimo da época, que era de R$350,00] cada uma”. A repórter foi até o TRE, mas só foi atendida na rua, pelo interfone. Podiam pelo menos ter convidado a coitada para entrar e sentar.

Lua e XML

Eu sou daqueles que ainda não conseguiram entender o que existe de tão espetacular no tal XML. Até admito que ele possa ser bom para algumas aplicações, e talvez até possa ser a melhor opção para um ou outro caso, mas o fato é que se faz barulho demais sobre isso. Diz-se que “este programa usa arquivos XML” como se isso fosse um recurso do programa, uma vantagem para o usuário.
