The main purpose of the Gramods library is to simplify loading of platform dependent configurations into a pre-compiled application, while also simplifying the implementation of such applications. The aim is to be able to implement an application that employs execution and data synchronization over network and synchronized multi window rendering in a flexible and configurable way.

operator>>() [1/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		Eigen::Matrix3f &	m
	)

Stream operator reading nine values into an Eigen::Matrix3f.

This is typically used to read XML position and matrix attributes. This will read nine values from the stream.

operator>>() [2/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		Eigen::Matrix4f &	m
	)

Stream operator reading 9, 12 or 16 values into an Eigen::Matrix4f.

This is typically used to read XML position and matrix attributes. This will read 16 values from the stream.

operator>>() [3/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		Eigen::Quaternionf &	q
	)

Stream operator reading into an Eigen::Quaternionf.

This is typically used to read XML orientation and rotation attributes. Default behavior is to read four values (w x y z), but this behavior can be modified by prefixing with a keyword:

• quaternion w x y z, e.g. "quaternion 1 0 0 0": Enforce the default behaviour.
• ypr ay ap ar, e.g. "ypr 0.1 0 0": Using Euler angles for yaw-pitch-roll rotation, i.e. around axis Y, X and Z counter clockwise (right-handed), but by airplane convention with negative Y and Z, where every angle per default is expressed in radians.
• axisangle x y z a, e.g. "axisangle 0 1 0 0.1": Using axis for rotation and angle of rotation around this axis, where the angle is expressed counter clockwise (right-handed) per default in radians. The axis does not have to be normalized.
• angleaxis a x y z, e.g. "angleaxis 0.1 0 1 0": Using axis for rotation and angle of rotation around this axis, where the angle is expressed counter clockwise (right-handed) per default in radians. The axis does not have to be normalized.

operator>>() [4/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		Eigen::Vector2f &	v
	)

Stream operator reading two values into an Eigen::Vector2f.

This is typically used to read XML position and vector attributes. This will read three values (x y) from the stream.

operator>>() [5/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		Eigen::Vector3f &	v
	)

Stream operator reading three values into an Eigen::Vector3f.

This is typically used to read XML position and vector attributes. This will read three values (x y z) from the stream.

operator>>() [6/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		gmCore::angle &	v
	)

Stream operator reading into a angle.

This is typically used to read XML angle attributes. Default behavior is to read a single value in radians, but the value is interpreted as degrees if it is prepended by a 'd' (as in 'd180'). The value can also be prepended by an 'r' (as in r3.14) to suppress the warnings that degrees probably was ment for large values.

operator>>() [7/20]

std::istream & gramods::operator>>	(	std::istream &	in,
		gmGraphics::Eye &	e
	)

Stream operator reading into an Eye.

This is typically used to read XML attributes. This will recognize "MONO", "LEFT" and "RIGHT".
