double Util::atod ( QString s )

Convert a QString to double.

makes a double precision value from a QString implemented because I called a function atod () ages ago, for convenience

Parameters:

s	string to be converted

Returns:: its numerical value; The double precision value of the argument

Referenced by Script::ParmStmt< T >::execute().

double Util::atod ( const std::string & )

Convert a string to unsigned.

Returns:: The double precision value of the argument

int Util::atoi ( const std::string & )

Convert a string to signed int.

Returns:: The integer value of the argument

void Util::CheckGLErrors ( const char * )

debug function for OpenGL commands; outputs all current GL errors on cerr

Parameters:

op	optional repetition of last GL command

std::vector< std::string > Util::explode	(	const std::string &	delimiter,
		const std::string &	str
	)

Splits a string on each occurrence of delimiter.

Parameters:

delimiter	The string at which `str` is split.
str	The string which is split into its part

Returns:: The list of parts of str. delimiter is not included in any of the parts.

template<typename T >

std::vector<T>::iterator Util::find	(	T	find_me,
		std::vector< T > &	v
	)

Find an element in a vector.

Parameters:

find_me	The element to find in the vector `v`
v	The vector to search for element `find_me`

Returns:: The vector<T>::iterator pointing to the element or v.end() if it is not in v

Here is the call graph for this function:

std::string Util::ftoa ( double x )

makes a string from a double value implemented because I called a function ftoa () ages ago, for convenience

Parameters:

x	number to be converted

Returns:: its string representation

Referenced by VecMath::RotationAxes< D >::axis(), and C4DView::RenderScene().

Here is the caller graph for this function:

std::string Util::trim ( const std::string & str )

Strips leading and trailing whitespace from a string.

Parameters:

str	A string to trim.

Returns:: str without leading and trailing whitespace.

VecMath::Vector< 3, double > Util::vnormalize	(	double	xx,
		double	yy,
		double	zz
	)

normalizes a Vector made from 3 doubles out-of-place

Parameters:

xx	x component of Vector to be normalized
