Detailed Description

CoordsysNode renders A coordinate system.

TODO: Den Fall mode_ == POSITION implementieren. 25.11.08

TextNode can be used to display a string on quads in OpenGL. This string can be set with setText(std::string _text). A TextNode can be attached to a parent node by using the function BaseObjectData::addAdditionalNode. The quads can then be set to align to the parent (OBJECT_ALIGNED) via the setRenderingMode(TextMode _textMode) function. Alternatively the quads can be aligned to the screen (SCREEN_ALIGNED). The font that is used to display text on the screen can be set with the setFont(const QFont& _font) function. Finally the quads can be scaled via the setSize(double _size) function.
