Member Function Documentation

static SurfaceType gazebo::common::SphericalCoordinates::Convert ( const std::string & _str)

static

Convert a string to a SurfaceType.

Parameters

[in] _str String to convert.

Returns: Conversion to SurfaceType.

static double gazebo::common::SphericalCoordinates::Distance	(	const math::Angle &	_latA,
