Member Function Documentation

double coding (  CodingMode  mode, const unsigned char *  data )  [static]

return the height using the given coding mode. The data pointer points to RGB data point

virtual const osg::HeightField* getHeightField (   )  const [inline, virtual]

void init (  const OsgHandle &  osgHandle, Quality  quality = Middle )  [virtual]

Initialisation of the primitive. Must in order to place the object into the scene. This function should be overloaded Implements OSGPrimitive.

HeightField * loadFromPPM (  const std::string &  filename, double  height, CodingMode  codingMode = Red )  [static]

loads an ppm image and returns the height field using the given coding and the height (maximal height of the heightfield)

void setMatrix (  const osg::Matrix &  matrix  )  [virtual]

Sets the transformation matrix of this object (position and orientation). Reimplemented from OSGPrimitive.
