inline void setType(Type type)

Set the Transform Type, which can be DYNAMIC - the Marix value is updated duing the main loop, or STATIC - the Matrix is constant throughut the life of the main loop.

Documentation

Transform - is group which all children are transformed by the the Transform's osg::Matrix. Typical uses of the Transform is for positioning objects within a scene or producing trakerball functionality or for animation.

Transform()

Transform(const Matrix& matix)

META_Node(Transform)

enum Type

Range of type that the Transform can be

DYNAMIC

STATIC

inline void setType(Type type)

Set the Transform Type, which can be DYNAMIC - the Marix value is updated duing the main loop, or STATIC - the Matrix is constant throughut the life of the main loop. STATIC Transforms can be optimized away is some instances, which can improve performanc so unless you plan to modify the Matrix explicity set the Matrix to STATIC. The default value is DYNAMIC.

inline const Type getType() const

inline const Matrix& getMatrix() const

inline void setMatrix(const Matrix& mat )

inline void preMult( const Matrix& mat )

preMult trasforms relative to the childrens coordinate system

inline void postMult( const Matrix& mat )
