INVRS_SYSTEMCORE_API void addTransformationToBinaryMsg	(	TransformationData *	data,
		NetMessage *	dst
	)

INVRS_SYSTEMCORE_API TransformationData& convert	(	const SensorData &	src,
		TransformationData &	dst
	)

Converts SensorData into TransformationData (simply by setting scale to 1 and scaleOrientation to the identity quaternion)

Parameters:

	src	SensorData which should be converted
	dst	TransformationData where the result is written to

Returns:

reference to dst

INVRS_SYSTEMCORE_API TransformationData& invert	(	TransformationData &	dst,
		const TransformationData &	src
	)

Inverts a TransformationData. Multiplying a TransformationData with its inverse results in an identity TransformationData.

Parameters:

	dst	TransformationData which will hold the inverse of src after call
	src	TransformationData which should be inverted

Returns:

returns dst

INVRS_SYSTEMCORE_API bool isIdentityTransformation

(

TransformationData &

toCmp

)

INVRS_SYSTEMCORE_API bool isInside	(	gmtl::Vec3f	pos,
		Entity *	entity
	)

This method returns if the passed Position is inside the BoundingBox of the passed Entity.

Parameters:

	pos	Position in world coordinates
	entity	Entity to check

Returns:

true, if the position is inside

INVRS_SYSTEMCORE_API TransformationData& matrixToTransformationData	(	const gmtl::Matrix44f &	src,
		TransformationData &	dst
	)

Converts a matrix into a TransformationData. In general it cannot be expected that transformationDataToMatrix() and matrixToTransformationData() are inverse to each other. This method might be time consuming.

Parameters:

	src	matrix which should be converted
	dst	TransformationData where the result is written to

Returns:

returns dst

INVRS_SYSTEMCORE_API TransformationData& multiply	(	TransformationData &	dst,
		const TransformationData &	second,
		const TransformationData &	first
	)

Performs a matrix, matrix multiplication: C = A * B

Parameters:

	first	TransformationData describing matrix B
	second	TransformationData describing matrix A
	dst	TransformationData where the resulting TransformationData is written to

Returns:

returns dst for conveniece

INVRS_SYSTEMCORE_API gmtl::Quatf& setQuatfAsAxisAngleDeg	(	gmtl::Quatf &	dst,
		float	x,
		float	y,
		float	z,
		float	deg
	)

INVRS_SYSTEMCORE_API void singularValueDecomposition	(	const gmtl::Matrix44f &	src,
		gmtl::Matrix44f &	q,
		gmtl::Matrix44f &	s,
		gmtl::Matrix44f &	p
	)

src = q * s * p where p, q orthogonal and s a diagonal matrix only the 3x3 part is considered

INVRS_SYSTEMCORE_API Entity* smallerBBox	(	Entity *	e1,
		Entity *	e2
	)

This method simply compares the size of the BoundingBoxes of 2 Entities and returns the Entity with the smaller box.

Parameters:

	e1	Entity to compare
	e2	Entity to compare with

Returns:

Entity with the smaller BoundingBox

INVRS_SYSTEMCORE_API gmtl::Matrix44f& transformationDataToMatrix	(	TransformationData	src,
		gmtl::Matrix44f &	dst
	)

Converts a TransformationData into a matrix

Parameters:

	src	TransformationData which should be converted
	dst	matrix

Returns:

returns reference to dst

INVRS_SYSTEMCORE_API void transformVector	(	gmtl::Vec4f &	dst,
		TransformationData &	transf,
		gmtl::Vec4f &	src
	)

Transforms a vector by a TransformationData transf. See TransformationData struct for a more detailed description of how a vector is transformed by a TransformationData.

Parameters:

	dst	transformed vector
	transf	TransformationData describing the transformation
	src	vector which should be transformed
