Function Documentation

template<typename Scalar >

Scalar ACG::bsplineBasisDerivative	(	int	_i,
		int	_degree,
		Scalar	_t,
		int	_der,
		const std::vector< Scalar > &	_knots
	)

Compute derivative of a single basis function.

Uses the recursive definition of the basis function. This is slower than using bsplineBasisDerivatives() for all values in a span.

Parameters

_i	index of basis function
_degree	spline degree
_t	parameter value
_der	order of derivative
_knots	knotvector

Returns: derivative of basis function value

Definition at line 334 of file BSplineBasis.cc.

template<typename Scalar >

void ACG::bsplineBasisDerivatives	(	std::vector< Scalar > &	_ders,
		const Vec2i &	_span,
		Scalar	_t,
		int	_der,
		const std::vector< Scalar > &	_knots,
		std::vector< Scalar > *	_functionVals
	)

Compute derivatives of basis functions in a span.

Uses a fast algorithm to compute all derivatives of basis functions in a span. The output vector _ders must have enough space to hold _span[1] - _span[0] values.

Parameters

_ders	output derivative values of all basis functions in the span
_span	span of the parameter _t
_t	parameter value
_der	order of derivative (ie. first, second, third order...)
_knots	knotvector
_functionVals	output basis function values, null is accepted (optional)

Definition at line 173 of file BSplineBasis.cc.

template<typename Scalar >

Scalar ACG::bsplineBasisFunction	(	int	_i,
		int	_degree,
		Scalar	_t,
		const std::vector< Scalar > &	_knots
	)

Evaluate a single basis function.

Uses the recursive definition of the basis function. This is slower than using bsplineBasisFunctions() for all values in a span.

Parameters

_i	index of basis function
_degree	spline degree
_t	parameter value
_knots	knotvector

Returns: basis function value

Definition at line 295 of file BSplineBasis.cc.

template<typename Scalar >

void ACG::bsplineBasisFunctions	(	std::vector< Scalar > &	_N,
		const Vec2i &	_span,
		Scalar	_t,
		const std::vector< Scalar > &	_knots
	)

Evaluate basis functions in a span.

Uses a fast algorithm to compute all basis functions in a span. The output vector _N must have enough space to hold _span[1] - _span[0] values.

Parameters

_N	output basis function values
_span	span of the parameter _t
_t	parameter value
_knots	knotvector

Definition at line 125 of file BSplineBasis.cc.

template<typename Scalar >

Vec2i ACG::bsplineSpan	(	Scalar	_t,
		int	_degree,
		const std::vector< Scalar > &	_knots
	)

Find the span of a parameter value.

Parameters

_t	parameter value
_degree	spline degree
_knots	knotvector

Definition at line 77 of file BSplineBasis.cc.

bool ACGDLLEXPORT ACG::checkExtensionSupported ( const std::string & _extension )

Check if the extension given by a std::string is supported by the current OpenGL extension

Cache glGetString(...) output because depending on the graphics driver it might return 0 the second time we call it.

Definition at line 73 of file gl.cc.

void ACG::glCheckErrors ( )

inline

Nice wrapper that outputs all current OpenGL errors to std::cerr. If no error is present nothing is printed.

Definition at line 105 of file GLError.hh.

std::string ACGDLLEXPORT ACG::glErrorToString ( GLenum _error )

replaces the gluErrorToString function at least for the standard OpenGL Headers

Definition at line 69 of file GLError.cc.

bool ACGDLLEXPORT ACG::openGLVersion	(	const int	_major,
		const int	_minor
	)

Check if OpenGL Version is greater or equal than the given values

Definition at line 95 of file gl.cc.
